Because dwarfing rootstocks send out only shallow root systems, they need to be staked, so the trees don't collapse under their own weight.
|
|
Modern orchards, with their reliance on dwarf trees, varietal selections, clonal rootstocks and chemically supported monocultures, are weak and practically require industrial crutches.
|
|
Undaunted, they went ahead with their plans, planting neat rows of the commonly used dwarfing rootstocks that keep orchard trees short and easy to pick.

In 1912, Ronald Hatton initiated the work of classification, testing and standardisation of apple tree rootstocks. With the help of Dr Wellington, Hatton sorted out the incorrect naming and mixtures then widespread in apple rootstocks distributed throughout Europe. These verified and distinct apple rootstocks are called the "Malling series". The most widespread used was the M9 rootstock.

Dwarf rootstocks for apple trees can be traced as far back as 300 BCE, to the area of Persia and Asia Minor. Alexander the Great sent samples of dwarf apple trees to Aristotle's Lyceum. Dwarf rootstocks became common by the 15th century and later went through several cycles of popularity and decline throughout the world. The majority of the rootstocks used today to control size in apples were developed in England in the early 1900s.
|
|
One reason for grafting onto rootstocks is that this enables the grower to determine the tree's eventual size. Another desirable characteristic of rootstocks is environmental adaptability. This may be tolerance to wet/dry soil conditions, acidity/alkalinity of soil or even hot/cold air temperature.

A common technique to germinate avocados at home is to poke the avocado with toothpicks and leave it partially submerged in indirect light A young avocado sprout Avocados can be propagated by seed, taking roughly four to six years to bear fruit, although in some cases seedlings can take 10 years to come into bearing. The offspring is unlikely to be identical to the parent cultivar in fruit quality. Prime quality varieties are therefore propagated by grafting to rootstocks that are propagated by seed (seedling rootstocks) or by layering (clonal rootstocks). After about a year of growing in a greenhouse, the young rootstocks are ready to be grafted.

The East Malling Research Station conducted extensive research into rootstocks, and today their rootstocks are given an "M" prefix to designate their origin. Rootstocks marked with an "MM" prefix are Malling- series cultivars later crossed with trees of 'Northern Spy' in Merton, England. Most new apple cultivars originate as seedlings, which either arise by chance or are bred by deliberately crossing cultivars with promising characteristics. The words "seedling", "pippin", and "kernel" in the name of an apple cultivar suggest that it originated as a seedling.

In the mid-19th century, the phylloxera louse destroyed much of the Vitis vinifera grape crop in Europe, especially France. Missouri's state entomologist, Charles Riley, found that American rootstocks were resistant to the pest. He directed sending millions of rootstocks to vineyards around the world., to which their grape varieties could be grafted.

Hatton was director at East Malling for thirty years. During that time he greatly expanded both its size and its range of activities. His principal achievement was the rationalisation, standardisation and classification of rootstocks for fruit trees. His work led to the establishment first of the Malling series, and later, in collaboration with the John Innes Horticultural Institution, of the Malling-Merton rootstocks for apples.

After olive pips were collected from the ancient Bidni olive grove of Bidnija, these were then sowed at the Government of Malta's Experimental Farm in Għammieri and left to germinate for use as rootstock. Once the rootstocks were viable, cuttings were then taken from the millennia-old Bidni olive trees and carefully grafted to the rootstocks. Efforts to plant more Bidni olive trees are ongoing.

Selection of rootstock cultivars can be difficult: vigorous roots tend to give trees that are healthy but grow too tall to be harvested easily without careful pruning, while dwarfing rootstocks result in small trees that are easy to harvest from, but are often shorter-lived and sometimes less healthy. Most modern commercial orchards use one of the "Malling series" (aka 'M' series), introduced or developed by the East Malling Research Station from the early 20th century onward. However, a great deal of work has been done recently introducing new rootstocks in Poland, the U.S. (Geneva), and other nations. The Polish rootstocks are often used where cold hardiness is needed.

Rootstocks that are bred for resistance to both GFLV and X. index have proven to be effective at managing the disease. An effective rootstock must be resistant to both the virus and the nematode. Hot water treatments of rootstocks to be planted ensures there will be little chance of the introducing the disease into the field. Preventing the introduction of infected plant or soil material is essential to manage both X. index and GFLV.

The Malling series is a group of rootstocks for grafting apple trees. It was developed at the East Malling Research Station of the South-Eastern Agricultural College at Wye in Kent, England. From about 1912, Ronald Hatton and his colleagues rationalised, standardised and catalogued the various rootstocks in use in Europe at the time under names such as Doucin and Paradise. Their first list had nine rootstock varieties, assigned the "type" numbers I–IX.

The rootstock or stock plant may be cut off above the bud at budding, or one may wait until it is certain that the bud is growing. Fruit tree budding is done when the bark "slips," i.e. the cambium is moist and actively growing. Rootstocks are young trees, either seedlings as Mazzard cherries for many cherry varieties, or clonal rootstocks (usually propagated by layering) when one wants highly consistent plants with well defined characteristics.

|
Owing to the common cultivation practice of grafting, Xylella fastidiosa often spreads into new orchards through the grafting of infected scion material on clean rootstocks or through infected rootstocks. Additionally, the disease is known to be vectored by certain insects. Thus far, three leafhoppers and two spittlebugs have been shown capable of transmitting the bacteria to pecan, with glassy-winged sharpshooters and adult pecan spittlebugs believed to be the primary vectors responsible for its spread.

Others, opposed to the idea, argued that American rootstocks would imbue the French grapes with an undesirable taste; they instead preferred to inject the soil with expensive pesticides. Ultimately, grafting American rootstock onto French vines became prevalent throughout the region, creating new grafting techniques and machines. American rootstocks had trouble adapting to the high soil pH value of some regions in France so the final solution to the pandemic was to hybridize the American and French variants.

The seeds of the pomelo are monoembryonic, producing seedlings identical to their parents, and therefore pomelo is typically grown from seed in Asia. Seeds can be stored for 80 days at and with moderate relative humidity. Citrus maxima is usually grafted onto other citrus rootstocks outside Asia; high-quality varieties are propagated by air-layering or by budding onto favored rootstocks. A wide variability in the physical and chemical characteristics of pomelo occurs across South Asia.

The new plant is severed only after it has successfully grown roots. Layering is the technique most used for propagation of clonal apple rootstocks. The most common method of propagating fruit trees, suitable for nearly all species, is grafting onto rootstocks. This in essence involves physically joining part of a shoot of a hybrid cultivar onto the roots of a different but closely related species or cultivar, so that the two parts grow together as one plant.

Jean-Baptiste Guillot (Père) opened a rose nursery in the La Guillotière area of Lyon in 1829, and Jean-Baptiste André (Fils) grew up working in the nursery from the age of 14. Guillot Père was the first nurseryman in Lyon to concentrate on the propagation of roses, produced new hybrids himself, and propagated and introduced new hybrids created by others, primarily Hybrid Perpetuals and Teas. Guillot Fils, while working for his father, pioneered the propagation of rose rootstocks from seed rather than cuttings. The roses used for rootstocks at that time were the wild species Rosa canina, the dog rose, and Rosa rubiginosa, the sweetbriar or eglantine.

Citrus blight reduces the size and quality of citrus crops, and as such can have a detrimental effect on the citrus industry. However, these effects can be mitigated. Trees can be planted on resistant rootstocks to ward off the effects of the blight. As the blight rarely kills trees, it is possible for an infected tree to produce years of profitable yields before the blight renders it uneconomical; for this reason, some sources recommend that citrus trees be planted on nonresistant but high-production rootstocks, the idea being that the rootstock - though susceptible to citrus blight - will allow for a citrus tree to produce enough crops to make it economical before the blight inevitably infects it.

Many growing and production methods are newer as most wineries have been in existence for only a short time. Many vineyards are new or recently replanted using modern cultivation techniques, improved rootstocks and cultivars. Most wines are fermented in stainless steel. Length of maceration and fermentation depends on the producer.

Certain species and cultivars can even flourish in tropical climates, especially when grafted onto appropriate rootstocks. Most garden roses prefer rich soil which is well- watered but well-drained, and perform best in well-lit positions which receive several hours of sun a day (although some climbers, some species and most Hybrid Musks will tolerate shade). Standard roses require staking.

The origin of muskmelons is not known. Research has revealed that seeds and rootstocks were among the goods traded along the caravan routes of the Ancient World. Some botanists consider muskmelons native to the Levant and Egypt, while others place their origin in India or Central Asia. Still others support an African origin, and in modern times wild muskmelons can still be found in some African countries.

It utilises high density planting on dwarfing rootstocks with a range between 2,500 and 3,300 trees/acre. Tall spindle systems utilise minimal pruning at planting, and uses branch bending to control growth, and limb pruning to renew branches as they become too large. As tree height exceeds 90% of the row spacing, fruit quality at the lower parts of the tree may be reduced.

The branch may lose its older leaves, and the leaves tend to be smaller with a bronzed complexion. The rootstock that the cherry is grafted onto can play a significant role in the disease symptoms seen. Rootstocks of Mahaleb cherry exhibit different symptoms from stocks of Colt, Mazzard, or Stockton Morello. When the scion is grafted onto Mahaleb, symptoms consistent with Phytophthora root rot can be seen.

Some of the more well-known developments have been achieved in the areas of plant raising, fruit plant culture (especially the development of rootstocks), fruit breeding, ornamental breeding, fruit storage and the biology and control of pests and diseases.Apples: British to the Core - BBC4 June 2011 by Artemisia annua From 1990 a division of Horticulture Research International (HRI) was on the site. HRI closed in 2009.

The plant grows as an erect shrub which is up to high, and blooms from March to April. It is a long-lived species, and survives fires by resprouting from underground boles or rootstocks. The plant is monoecious with both sexes in each flower; the wind-dispersed seeds are not stored on the plant and are released immediately after ripening. It is pollinated by birds.

But just as French vignerons were recovering from oidium came a new mysterious ailment that caused decay or death in the grapevines. The cause was a tiny louse, known as phylloxera, imported from North America. This louse targets the rootstock of the vine. The solution to this epidemic also came from North America in the grafting of naturally resistant American rootstocks to the European vines.

This apple tree responds well to plenty of water and is very strong but cannot stand frost (fruits tend to burst) or dry soil. The cultivar is compatible with most rootstocks, but its pollen quality is poor because it is a triploid. Cultivars that can provide compatible pollen for 'Belle de Boskoop' include 'Discovery', 'James Grieve', 'Melba' and 'Reine des Reinettes'. The apple stores well after harvest.

Like all Prunus fruits, it contains a single large seed, usually called a stone, which is discarded when eating. Plums are grown commercially in orchards, but modern rootstocks, together with self-fertile strains, training and pruning methods, allow single plums to be grown in relatively small spaces. Their early flowering and fruiting means that they require a sheltered spot away from frosts and cold winds.

Useful rootstocks include wild grapefruit, cleopatra mandarin and tahiti limes. C. macrophylla is also sometimes used as a rootstock in Florida to add vigor. Climatic conditions and fruit maturation are crucial in cultivation of the lime tree. Under consistently warm conditions potted trees can be planted at any season, whereas in cooler temperate regions it is best to wait for the late winter or early spring.

A systematic account of the family Asteraceae (chapter 11: tribe Helenieae). Phytologia Memoirs 16: 1–100 Helenium chihuahuense is a branching annual herb up to 78 cm (31.2 inches) tall with thick rootstocks producing only one stem with a single flower head. The leaves are long, narrow and irregularly lobed. The head is spherical or egg-shaped, with many disc flowers, each yellow with purple tips.

|
Mourvèdre produces medium-size, compact bunches that are usually conical in shape with a small wing cluster that may be discarded during green harvesting. The leaves often have truncate cuneiform "wedge" shape. Since World War II, newer clones and better rootstock have been developed that have allowed Mourvèdre vines to be grafted more easily. Today many plantings of Mourvèdre are to 110R and 41B rootstocks.

|
Some species of Scabiosa are annuals, others perennials. Some are herbaceous plants; others have woody rootstocks. The leaves of most species are somewhat hairy and partly divided into lobes, but a few are smooth and some species have simple leaves. The flowers are borne on inflorescences in the form of heads; each head contains many small florets, each floret cupped in a membranous, saucer-shaped bract.

Habit Antigonon leptopus is a fast-growing climbing vine that holds on via tendrils, and is able to reach 25 ft or more in length. It has cordate (heart- shaped), sometimes triangular leaves 2½ to 7½ cm long. The flowers are borne in panicles, clustered along the rachis. Producing pink or white flowers from spring to autumn, it forms underground tubers and large rootstocks.
|
|
They grow naturally only up to tall subshrubs, with the leafy above ground growth that dies back each dry season to the underground woody rootstocks. In South Africa three species grow naturally. The scarcity of A. natalensis trees and their restricted range has received the global conservation status (IUCN) of "vulnerable D2". A. capensis has a global conservation status (IUCN) listing also, of "Lower Risk / conservation dependent" .

Most of the plants harvested are collected in the provinces of Heilongjiang, Jilin, Inner Mongolia and Hebei. The tuberous rootstocks are harvested in early spring or late autumn (when the plants have yet to flower or have finished flowering) washed, trimmed of basal leaves and fibrous roots, sun-dried until they contain 20% moisture, shredded and then sun-dried again until completely desiccated and ready for storage.

Butterfly Conservation, Lulworth, England. was introduced to North America in 2010, with the supply of two small specimens to the USDA, Washington, D.C., released from quarantine in 2013. is not known to have been introduced to Australasia. Increasing by softwood cuttings is relatively straightforward, however these lose their viability as the trees mature, and French nurseries now resort to grafting onto 'Sapporo Autumn Gold' rootstocks.

V. berlandieri, which had adapted to limestone hills in central Texas, provided the lime tolerance needed to solve this problem. However, V. berlandieri itself is poorly adapted to grafting. Therefore, various rootstocks resistant against both phylloxera and lime, and suitable for viticulture, were produced by crossing V. berlandieri and Vitis riparia, Vitis rupestris or V. vinifera.UC Davis: Vitis berlandieri Vitis berlandieri is also known as Fall Grape.

The species was first introduced to cultivation in England in 1856 and by 1858 was in cultivation at the Royal Botanic Gardens, Melbourne. Though widely grown, it has a reputation for being short lived. This problem, which is accentuated in humid climates with summer rainfall, has been addressed by grafting on various rootstocks. G. alpina grows best in dry environments and does not tolerate excess moisture well.

|
Management practices consist of exclusion, preventive measures, and post-planting nematicide applications. All growers should avoid contaminated nursery rootstocks and use certified nematode-free soil and nematode-free rootstock (it is obligatory in some areas). Nematodes can easily be removed from seedlings by dipping the roots in 45 C water for 25 min, this kills the nematodes but does not harm the plant.Verdejo-Lucas, S.,and D.T.Kaplan. 2002.

Chile is now the fifth largest exporter of wines in the world, and the seventh largest producer.OIV press report October 2015 The climate has been described as midway between that of California and France. The most common grapes are Cabernet Sauvignon, Merlot and Carmenère. So far Chile has remained free of the phylloxera louse, which means that the country's grapevines do not need to be grafted with phylloxera-resistant rootstocks.

Dorstenia contrajerva, by von Jacquin, 1793. Dorstenia contrajerva is a plant species in the family Moraceae. It is native to Northern South America and Central America, and is cultivated elsewhere. The species name "contrajerva" is the Latinized form of the plant's Spanish name, "contrahierba," a name for plants used for treating poisoning and venomous bites and stings, and for which its rootstocks are used in folk medicine (as contrayerva).

Propagation is usually by seeds, which can remain viable for 2 years kept dry and in the dark, though air-layering and grafting are possible to preserve specific cultivars. Grafting onto rootstocks of Annona montana or Annona glabra causes dwarfing. Little work establishing superior cultivars has been done and considerable genetic variability exists. ‘Regnard’ is perhaps the best known cultivar, which was introduced into the Philippines in 1917.

Cicuta spp. are perennial plants that are all similar in morphology, growing up to a maximum of in height. The stem of the plant is branching, erect, smooth and hollow (except for partitions at the junction of the leaves and stem), sometimes being purple-striped, or mottled (typically only C. maculata has the purple stripes or spots). Attached to the base of the stem is a tuberous root with thickened rootstocks.

Lobel's maple is grown as an ornamental tree in northern Europe, valued for its narrow crown which makes it suitable for planting in confined spaces. Many of the trees in cultivation are grafted on Acer cappadocicum rootstocks, shown by the numerous root sprouts with Acer cappadocicum foliage. The horticultural hybrid maple Acer × zoeschense is often cited as having Acer lobelii as one of its parents, though more likely Acer cappadocicum.

Cheilanthes (lip ferns) is a genus of about 180 species of rock-dwelling ferns with a cosmopolitan distribution in warm, dry, rocky regions, often growing in small crevices high up on cliffs. Most are small, sturdy and evergreen. The leaves, often densely covered in trichomes, spring directly from the rootstocks. Many of them are desert ferns, curling up during dry times and reviving with the coming of moisture.

Schoenolirion wrightii, known as Texas sunnybell, is a species of flowering plant in the Agave subfamily. It is native to the southern United States, in Texas, Louisiana, Arkansas, and Alabama. Texas sunnybell produces vertical rootstocks topped with prominent bulbs, each up to in diameter. Between two and seven leaves are produced per plant, up to long and only across each, flattened to slightly keeled and usually shorter than the flowerhead.

In 1911 the phylloxera plague destroyed the vineyards, but the producers of the area were able to save their industry by grafting new varieties of grapes (especially Airén) onto phylloxera-resistant New World rootstocks. This moment of crisis forced the different producers to cooperate with each other and a regional federation was formed, which was subsequently transformed into the Regulatory Council of the DOP. Official DO status was granted in 1932.

Pear tree According to Pear Bureau Northwest, about 3000 known varieties of pears are grown worldwide. The pear is normally propagated by grafting a selected variety onto a rootstock, which may be of a pear variety or quince. Quince rootstocks produce smaller trees, which is often desirable in commercial orchards or domestic gardens. For new varieties the flowers can be cross-bred to preserve or combine desirable traits.
|
|
Terminal and lateral grafting is normally used. The scion cultivar grows for another 6–12 months before the tree is ready to be sold. Clonal rootstocks are selected for tolerance of specific soil and disease conditions, such as poor soil aeration or resistance to the soil-borne disease (root rot) caused by Phytophthora. Commercial avocado production is limited to a small fraction of the vast genetic diversity in the species.
|
|
The process of joining the two varieties must ensure maximum contact between the cambium (the layer just below the bark) of each, so that they grow together successfully. Grafting is a preferred method because it not only propagates a new plant of the desired hybrid cultivar, it usually also confers extra advantages as a result of the characteristics of the rootstocks (or stocks), which are selected for characteristics such as their vigour of growth, hardiness and soil tolerance, as well as compatibility with the desired variety that will form the aerial part of the plant (called the scion). For example, grape rootstocks descended from North American grapes allow European grapes to be grown in areas infested with Phylloxera, a soil- dwelling insect that attacks and kills European grapes when grown on their own roots. Two of the most common grafting techniques are "whip and tongue", carried out in spring as the sap rises, and "budding", which is performed around the end of summer.

|
There are thousands of cultivars of these three species. A species grown in western China, P. sinkiangensis, and P. pashia, grown in southern China and south Asia, are also produced to a lesser degree. Other species are used as rootstocks for European and Asian pears and as ornamental trees. Pear wood is close-grained and at least in the past was used as a specialized timber for fine furniture and making the blocks for woodcuts.

Dogfennel spreads by both seeds and rootstocks and can grow quite aggressively. It is common in pastures, especially those that are unimproved or overgrazed, and degrades the quality of the pasture by competing with desired forage species. Dogfennel contains liver-damaging pyrrolizidine alkaloids, so livestock are known to eat all the turf around a stand of it. To remove infestations of dogfennel, the recommended course of action is to mow it before it can seed.

Stanisław Wojciech Zagaja (11 May 1925 in Szczurowa, Poland – 17 December 2004 in Skierniewice, Poland) was a Polish pomologist, grower of orchard plants. Professor (since 1963) and director (since 1984) of the Research Institute of Pomology and Floriculture in Skierniewice, member of Polish Academy of Sciences since 1983. His research was focused on fruit tree breeding, selection and seed physiology as well as working with apple vegetative rootstocks, and hybrids of peach and cherry.

The hairy water lily is an aquatic plant having erect perennial rhizomes or rootstocks that anchor it to the mud in the bottom. The rhizomes produce slender stolons. Its leave blades are round above the water and heart-shaped below 15–26(–50) cm, papery, abaxially densely pubescent. Some of the leaves that emerge rise slightly above the water held by their stem in lotus fashion, but most of them just float on the surface.

Fruitlet of Ponderosa lemon Ponderosa lemon is not widely grown commercially, but it is commonly grown as an ornamental plant. In areas where the winter's cold may damage the plant, they are grown in containers. In such cases they are usually grafted to dwarf rootstocks to help maintain a smaller, more manageable size. The impressive sized fruits may be left on the tree for many months after they've ripened without a drop in the fruits' quality.

Although Castanea can grow in very acid soil, and while these soils are reasonably well tolerated, the preferred range is from pH 5.5-6.0. It does not grow well on alkaline soils, such as chalk, but thrives on soils such as those derived from granite, sandstone, or schist. On alkaline soils, chestnut trees can be grown by grafting them onto oak rootstocks. Recently cleared land is best avoided to help resist the root rot, Armillaria mellia.

Hoare, A. (1928) The English Grass Orchard and the Principles of Fruit Growing, Benn, p.212 Management techniques did not use fertiliser or chemicals, other than the natural fertilisation from the dung of grazing cattle, and generally required less training than modern, high-density systems. Budding of scions took place high up in the tree, typically using vigorous rootstocks or seedlings. Traditional orchards have been found to produce apples with lower nitrogen content and higher polyphenolic levels.

Different cultivars of durian often have distinct colours. D101 (right) has rich yellow flesh, clearly distinguishable from another variety (left). Over the centuries, numerous durian cultivars, propagated by vegetative clones, have arisen in Southeast Asia. They used to be grown with mixed results from seeds of trees bearing superior quality fruit, but now are propagated by layering, marcotting, or more commonly, by grafting, including bud, veneer, wedge, whip or U-grafting onto seedlings of randomly selected rootstocks.

In the late 19th century the phylloxera epidemic devastated the area wiping out the majority of the region's vines. While some Pinot noir vines were retained most of the Gamay was lost.A. Domine (ed) Wine pg 230-231 Ullmann Publishing 2008 They were replanted with Sauvignon Blanc, partly because it grafted better onto the American rootstocks. After World War II, the wines gained a reputation in the Paris bistro scene as an easy drinking white wine equivalent to Beaujolais.

Vegetative propagation is usually considered a cloning method. However, root cuttings of thornless blackberries (Rubus fruticosus) will revert to thorny type because the adventitious shoot develops from a cell that is genetically thorny. Thornless blackberry is a chimera, with the epidermal layers genetically thornless but the tissue beneath it genetically thorny.. Grafting is often not a complete cloning method because seedlings are used as rootstocks. In that case, only the top of the plant is clonal.
|
|
In some crops, particularly apples, the rootstocks are vegetatively propagated so the entire graft can be clonal if the scion and rootstock are both clones. Apomixis (including apospory and diplospory) is a type of reproduction that does not involve fertilization. In flowering plants, unfertilized seeds are produced, or plantlets that grow instead of flowers. Hawkweed (Hieracium), dandelion (Taraxacum), some citrus (Citrus) and many grasses such as Kentucky bluegrass (Poa pratensis) all use this form of asexual reproduction.

The developmental sequence of a nectarine over a -month period, from bud formation in early winter to fruit ripening in midsummer Most peach trees sold by nurseries are cultivars budded or grafted onto a suitable rootstock. Common rootstocks are 'Lovell Peach', 'Nemaguard Peach', Prunus besseyi, and 'Citation'. This is done to improve predictability of the fruit quality. Peach trees need full sun, and a layout that allows good natural air flow to assist the thermal environment for the tree.

Lemons are a citrus fruit native to Asia, but now common worldwide. Citrus trees hybridise very readily – depending on the pollen source, plants grown from a Persian lime's seeds can produce fruit similar to grapefruit. Thus, all commercial citrus cultivation uses trees produced by grafting the desired fruiting cultivars onto rootstocks selected for disease resistance and hardiness. Limes in a grocery store The colour of citrus fruits only develops in climates with a (diurnal) cool winter.

Between 1934 and 1994, only the local co-op could use the Colares appellation. Because grapevines there are grown directly upon the sand, and phylloxera aphids cannot live on sand, Colares vineyards are some of the only European vines that are not grafted upon American rootstocks. The ungrafted Ramisco vines of the Colares region are some of the oldest in Portugal. The region is known for its deep colored, full bodied red wines that are high in astringent tannins.

Ulmus 'Columella' is a Dutch elm cultivar raised by the Dorschkamp Research Institute for Forestry & Landscape Planning, Wageningen, from a selfed or openly pollinated seedling of the hybrid clone 'Plantyn' sown in 1967. It was released for sale in 1989 after proving extremely resistant to Dutch elm disease following inoculation with unnaturally high doses of the pathogen, Ophiostoma novo-ulmi. However, propagated by grafting onto Wych Elm rootstocks, graft failure owing to incompatibility has become a common occurrence in the Netherlands.

With the move to higher density plantings, different tree types and planting systems have been developed, and are used around the world. These systems include: Central leader trees are commonly grown in a conical shape, with a central vertical shoot (the central leader), and horizontal larger branches at the bottom decreasing to smaller branches near the top. Central leader trees grown with standard or semi dwarf rootstocks are large and free standing, unlike modern high density plantings.Baugher, T. A. 2003.

A systematic account of the family Asteraceae (chapter 11: tribe Helenieae). Phytologia Memoirs 16: 1–100 Helenium apterum is an perennial herb up to 100 cm (40 inches) tall with thick rootstocks producing only one stem with a single flower head. Leaves at the base can be up to 30 cm (1 foot) long, the leaves higher on the stem much smaller. The head is about 4 cm (1.6 inches) across, with a hemispherical yellow disc surrounded by about 14 yellow ray flowers.

Root sprouts and basal shoots can be used to propagate woody plants. Root sprouts can be dug or severed with some of the roots still attached. As for basal shoots, stool beds involve cutting a juvenile plant proximate to the surface of the soil and heaping soil over the cut so that basal shoots will form adventitious roots and later can be severed to form multiple, rooted, new plants. The technique is used especially for vegetative propagation of rootstocks for apple trees.

Box huckleberry is self-sterile, so single plants cannot reproduce sexually. Instead, they form colonies which spread by vegetative reproduction along rootstocks. A colony of G. brachycera at Losh Run, Pennsylvania was found to be long when surveyed. If this colony grew clonally from a seed deposited along the Juniata River at the rate of per year, it would be about 13,000 years old, the oldest living organism in the United States and second oldest in the world, eclipsed only by Lomatia tasmanica.

Propagation involves two stages: first, a rootstock is grown from seed. Then, when it is approximately one year old, the leafy top is cut off and a bud taken from a specific scion variety, is grafted into its bark. The scion is what determines the variety of orange, while the rootstock makes the tree resistant to pests and diseases and adaptable to specific soil and climatic conditions. Thus, rootstocks influence the rate of growth and have an effect on fruit yield and quality.

The rushes are harvested and the leaves often dried for later use in chair seats. Re-wetted, the leaves are twisted and wrapped around the chair rungs to form a densely woven seat that is then stuffed (usually with the left over rush). Small-scale experiments have indicated that Typha are able to remove arsenic from drinking water. The boiled rootstocks have been used as a diuretic for increasing urination, or mashed to make a jelly-like paste for sores, boils, wounds, burns, scabs, and smallpox pustules.

Symptoms can include, but are not limited to: root-pruning, decreased nutrient uptake, vascular damage, possible death of shoots and limbs, and stunted plant growth. With the reduced nutrient uptake, some cases have shown that the change in ratio if carbon:nitrogen can make plants infected by ring nematodes more susceptible to bacterial canker cause by Pseudomonas syringae, (Lownsberry, et al. 1977).Lownsbery, B.

Trees grafted on dwarfing rootstocks bear about of fruit per year. Farms with apple orchards open them to the public so consumers can pick their own apples. Crops ripen at different times of the year according to the cultivar. Cultivar that yield their crop in the summer include 'Gala', 'Golden Supreme', 'McIntosh', 'Transparent', 'Primate', 'Sweet Bough', and 'Duchess'; fall producers include 'Fuji', 'Jonagold', 'Golden Delicious', 'Red Delicious', 'Chenango', 'Gravenstein', 'Wealthy', 'McIntosh', 'Snow', and 'Blenheim'; winter producers include 'Winesap', 'Granny Smith', 'King', 'Wagener', 'Swayzie', 'Greening', and 'Tolman Sweet'.

A bush orchard near Cowleigh, United Kingdom.In response to the rising demand for cider apples in the United Kingdom in the 1950s, the Long Ashton Research Station developed the bush orchard system commonly used in the UK today. Cider apple varieties are grafted onto semi-dwarfing rootstocks and reach a maximum height of 15 to 20 feet (4.5 to 6 m). Trees are planted at a density of approximately 750 per hectare, with trees spaced 2 – 3 m (6.5-10 ft) apart in rows 5.5m (18ft) wide.

In this competitive climate, the Spanish king sent an executive order to halt Mexico's production of wines and the planting of vineyards. During the devastating phylloxera blight in late 19th-century Europe, it was found that Native American vines were immune to the pest. French-American hybrid grapes were developed and saw some use in Europe, but more important was the practice of grafting European grapevines to American rootstocks to protect vineyards from the insect. The practice continues to this day wherever phylloxera is present.

These varieties do in fact possess many of the traits of Vitis labrusca, frequently including slipskin fruit, strong "foxy" flavor/odor, and large leaves with lighter colored and pubescent undersides. Most are self-fertile, unlike wild Vitis labrusca. For much of the history of American viticulture, such varieties made up the bulk of production, particularly outside of California. In more recent years, however, the introduction of chemical pesticides and the development of rootstocks able to tolerate phylloxera have reduced their importance considerably in favor Vitis vinifera.

The rootstocks are multichambered and contain a yellowish oily liquid which turns reddish brown on exposure to air and emits a characteristic smell of raw parsnip. The alternate leaves are 2 or 3 pinnately compound and may reach to in length. The leaflets are lanceolate, serrate, to in length, and sharply toothed. The plant flowers in spring or early summer; the flowers are small with green or white petals clustered in an umbrella shape (umbel) characteristic to this family; the umbel measures to across.

Traditionally, Typha latifolia has been a part of certain indigenous cultures of British Columbia, as a source of food, medicine, and for other uses. The rhizomes are edible after cooking and removing the skin, while peeled stems and leaf bases can be eaten raw, or cooked. The young flower spikes, young shoots, and sprouts at the end of the rootstocks are edible as well.Turner, Nancy J. Food Plants of Interior First Peoples (Victoria: UBC Press, 1997) The starchy rootstalks were ground into meal by Native Americans.

CPsV-EG isolate was transmitted from infected citrus to citrus by syringe and grafting and herbaceous plants by forefinger inoculation and syringe. The woody indicators and rootstocks were differed in response to CPsV-EG isolate which appeared as no-response, response, sensitivity and hypersensitivity. A partial fragment of RNA3 (coat protein gene) of CPsV-EG (–1140bp and –571bp) was amplified by reverse transcription-polymerase chain reaction (RT-PCR) from grapefruit tissues using two sets primers specific CPsV (CPV3 and CPV4) and (PS66 and PS65) respectively.

He became a specialist horticulturalist with the department in 1959, and worked on developing rootstocks and strategies to optimise horticultural production in Western Australia. In 2010, he was inducted into the Hall of Fame of the Royal Agricultural Society of Western Australia for significant influence on the apple industry of Australia. In 2015, he was made an Officer of the Order of Australia (AO) for distinguished service to primary industry through internationally renowned, innovative contributions to the agriculture and food sectors, and to the community.

In 1967, Auvil came up with the practice and use of "undertree sprinklers" for the purpose of frost control. In 1968, Auvil established the "Tree Fruit Commission". In 1972, Auvil introduced the "Granny Apple" to the north western United States and in 1973 he had led the way in using the M26 rootstocks for practical use. In 1975, Auvil brought the "Rainier Cherry" to the north western United States and in the next year, he developed double row planting for Granny Smith apple trees.

'Palatina', a Hungary grape Phylloxera is an American root aphid that devastated V. vinifera vineyards in Europe when accidentally introduced in the late 19th century. Attempts were made to breed in resistance from American species, but many winemakers didn't like the unusual flavour profile of the hybrid vines. However, V. vinifera grafts readily onto rootstocks of the American species and their hybrids with V. vinifera, and most commercial production of grapes now relies on such grafts. The black vine weevil is another root pest.

With the aid of global warming and vigorous rootstocks, many Bordeaux vineyards can easily surpass 60 hl/ha, with some estates taking advantage of the legal loophole of plafond limite de classement ("ceiling limit classification") that permits higher yields during "exceptional" years. This has had an adverse effect on the quality of production from some producers who regularly use grapes harvested at excessive yields. In recent years there has been more of an emphasis on keeping yields low, particularly for an estate's Grand vin.

Eventually, the sweet orange was grown in wide areas of the Hawaiian Islands, but its cultivation stopped after the arrival of the Mediterranean fruit fly in the early 1900s. As oranges are rich in vitamin C and do not spoil easily, during the Age of Discovery, Portuguese, Spanish, and Dutch sailors planted citrus trees along trade routes to prevent scurvy. Florida farmers obtained seeds from New Orleans around 1872, after which orange groves were established by grafting the sweet orange on to sour orange rootstocks.

Some of these imported rootstocks were infected with various virus such as corky bark, fanleaf and leafroll, which soon spread to other vineyards. These virus-infected vines have a shortened lifespan and difficulties with photosynthesis, which can lead to poor ripening of phenolic compounds in the grape and low quality wine. Since the 1980s, efforts have been undertaken by the South African wine industry to quarantine and promote healthy virus-free vineyards. Additionally, work has been undertaken in clonal research to identify which grape varieties grow best in which climate and wine region.

By 1990, there were 70 bonded Oregon wineries and 320 growers, with vineyard planted. The Oregon wine industry received a stern challenge from nature, when the Phylloxera root louse was discovered in Oregon. This necessitated the use of Phylloxera-resistant rootstocks, many vineyards took this as an opportunity to select different varieties of grapes more suited to their particular location. The Rogue Valley AVA was established; three years later, the Oregon Wine Marketing Coalition was founded. In 1995, the Oregon Legislature enacted several new laws which were beneficial to winemakers.

Heavy infestations can result in "psylla shock", caused by toxins in the saliva and resulting in defoliation or fruit drop, which may also affect the following year's crop. The psyllia can also carry mycoplasma in their saliva which can cause disease of the conducting cells in the tree's phloem. Failure of nutrients to be translocated downwards can cause root starvation, with trees either declining slowly or suffering from sudden collapse. Trees grafted onto Pyrus pyrifolia or Pyrus ussuriensis rootstocks are more susceptible to this disease than those on Pyrus communis.

Major is a 'bittersweet' under the categorisation system developed in 1903 by the Long Ashton Research Station, its fruit being high in tannins and relatively low in acidity. A long established variety dating from the 19th century or earlier, it was historically found in old farm orchards across South Devon and east of the Blackdown Hills in Somerset.Annual Report of the Long Ashton Research Station, 1986, p.64 A triploid variety, young trees of 'Major' are very vigorous in growth meaning it is unsuitable for use with some large-growing rootstocks.

It was spread down the Rhine to Alsace, by way of the Palatinate, where Gewürz (spice) was added to its name – presumably this was when one of the mutations happened. The longer name was first used in Alsace in 1870 – without the umlaut. It is not clear what this name change represents, as it seems too great a coincidence that the musqué mutation happened just after the arrival of the great phylloxera epidemic. More likely, an existing mutant was selected for grafting onto phylloxera-resistant rootstocks when the vineyards were replanted.

The Doña Margarita vineyard, named after Marimar’s mother, was planted in 2002 in the Freestone Valley of the Sonoma Coast AVA. Although the estate has , only 12 of these have been earmarked for vines and planted with Pinot noir. A large area of the estate remains uncultivated with wildlife and indigenous plant species. At the Sonoma vineyard, the estate utilizes traditional Mediterranean viticultural practices, such as a vertical trellis for the vines, the choice of rootstocks that are more resistant to phylloxera and a planting density of 2 m x 1m (2,000 vines per acre).

Using trees on vigorous rootstocks which will have a better chance of competing with the pathogens, or plants grown in large containers with a large root ball may also have a better chance of resisting replant disease. The extra time to cropping may be offset if new trees are planted a few years in advance of old trees finally falling over, furthermore, if the old orchard was grubbed - i.e. trees were healthy when removed, it is unlikely that replant disease would be a problem as pathogen levels may never have been high.

After the spectacular success of Missouri wines at the Vienna World Fair of 1851, taking 8 of the 12 medals on offer, the French responded by importing Norton / Cynthiana rootstocks from the US, and unwittingly introducing phylloxera, which then ravaged the vineyards of France, Spain, and Portugal during the 1870s. Jaeger, working with the Missouri state entomologist George Hussman, had already raised vines with resistance to the pest; he exported 17 boxcars of the resistant rootstock to France, which was to prove the salvation of the European wine industry.

The Marattiaceae diverged from other ferns very early in their evolutionary history and are quite different from many plants familiar to people in temperate zones. Many of them have massive, fleshy rootstocks and the largest known fronds of any fern. The Marattiaceae is one of two groups of ferns traditionally known as eusporangiate ferns, meaning that the sporangium is formed from a group of cells as opposed to a leptosporangium in which there is a single initial cell. The large fronds characteristic of the group are most readily found in the genus Angiopteris, native to Australasia, Madagascar and Oceania.

The occurrence of Burrknot is quite common among rootstock, often found on apple tree M ( Malling ) and MM ( Malling-Merton ) rootstocks. At onset it begins to look like a smooth orange bulge growing from the stem or a branch, later, during one to three years, multiple adventitious roots begin to form. When located on the roots, it is considered to be not very dangerous, but it makes it easier for diseases to infect the tree, and leaves it more susceptible to insects. When many burrknots are present on various location in the tree, it can make the tree unproductive.

Long-distance spread of the disease occurs through the planting of infected trees, as well as budding and grafting of infected tissue. To prevent the establishment of the disease, guidelines typically call for testing of rootstocks and budwood before planting, removal of all trees known and suspected to be infected and eradication of ornamental and wild cherry trees from the surrounding area. Short-distance spread of the disease occurs through transmission of the viruses by insect vectors. Little cherry virus-2 is spread by scale insects of the family Pseudococcidae, primarily the apple mealybug (Phenacoccus aceris).

The popular Malling-Merton series of rootstocks for apples was developed in England, and are used today for the majority of the commercial apple orchard trees. T-budding is the most common style, whereby a T-shaped slit is made in the stock plant, and the knife is flexed from side to side in the lower slit to loosen up the bark. Scion wood is selected from the chosen variety, as young, actively growing shoots. Usually, buds at the tip, or at the older parts of the shoot are discarded, and only two to four buds are taken for use.

In the 18th and 19th centuries, as the Colonial British Empire began to be influenced by India's elaborate food tradition of "strong, penetrating spices and herbs". The United Kingdom developed a worldwide reputation for the quality of British beef and pedigree bulls were exported to form the bloodline of major modern beef herds in the New World. Developments in plant breeding produced a multiplicity of fruit and vegetable varieties, with British disease-resistant rootstocks still used globally for fruits such as apples. During the World Wars of the 20th century difficulties of food supply were countered by official measures, which included rationing.

Hand picking is also widely used for sweet as well as sour cherries to harvest the fruit to avoid damage to both fruit and trees. Common rootstocks include Mazzard, Mahaleb, Colt, and Gisela Series, a dwarfing rootstock that produces trees significantly smaller than others, only 8 to 10 feet (2.5 to 3 meters) tall. Sour cherries require no pollenizer, while few sweet varieties are self-fertile. A cherry tree will take three to four years once it is planted in the orchard to produce its first crop of fruit, and seven years to attain full maturity.

Many ferns of this genus have stout, slowly creeping rootstocks that form a crown, with a vase-like ring of evergreen fronds long. The sori are round, with a circular indusium, except in South American species which lack an indusium. The stipes have prominent scales with often have hair- like cilia, but lack any true hairs. The genus differs from the well-known and allied fern genus Dryopteris in the indusium being circular, not reniform, and in having the leaf segments with auricles—asymmetrical blades where one side of the segment is much longer than the other at the base.

Rootstocks have been developed which convey resistance to the aphids to the roots but they do not appear to be effective against aerial infestation. Growers have also tried to prevent infestation by preventing the crawler stage of the nymph from climbing into the crown but these have proven ineffective as aphids can colonise the crown from neighbouring trees. As well as the parasitoid, Alphelinus mali, these aphids are preyed on by the bug Anthocoris nemoralis, ladybirds, hoverfly larvae and lacewings. The presence of earwigs Forficula auricularia on the trees can reduce the levels of aphid infestation, so encouraging these insects by providing shelters may be another means of biological control.

There is debate among scholars whether the abattiach in The Book of Numbers 11:5 refers to a muskmelon or a watermelon."We remember the fish, which we did eat in Egypt freely; the cucumbers, and the melons, and the leeks, and the onions, and the garlick" Both types of melon were known in Ancient Egypt and other settled areas. Some botanists consider muskmelons native to the Levant and Egypt, while others place the origin in Persia, India or Central Asia, but the origin is uncertain. Researchers have shown that seeds and rootstocks were among the goods traded along the caravan routes of the Ancient World.

Image of Iris tridentata flower capsule, which holds the seeds of the iris Iris tridentata is unique among other irises, the flowers and growth habit is dissimilar to any other iris, including the other two species within Iris series Tripetalae. The iris rhizome has been noted by W. R. Dykes (1913) as "almost stoloniferous", by J. K. Small (1933), "the cord-like rootstocks are peculiar", and by R. K. Godfrey and J. W. Wooton (1979), "clothed with coarse, strongly many-ribbed, brown, overlapping scales". The slender rhizomes, branch very easily creating large spreading colonies. They are generally 1.5–2 cm in diameter with coarse, strongly ribbed, brown, scale-like leaves.

Duke J.A., duCellier J.L. (1993): CRC handbook of alternative cash crops (page 139-145) Alternatively, vegetative propagation from cuttings or by air layering may permit fruit production within one year, and from genetically more predictable lines of plants. Another method, digging around a mature tree to sever roots, will encourage new sprouts that can be transplanted to another location. Clones are often bud grafted into rough lemon or sour orange to obtain strong root stocks (see also fruit tree propagation). It is often advisable to graft the plants onto rootstocks with low susceptibility to gummosis because seedlings generally are highly vulnerable to the disease.

Munson made extensive use of American native grape species, and devoted a great deal of his life to collecting and documenting them. He released hundreds of named cultivars, but his work identifying American native grape (especially those from Texas) is of great significance today for their use in rootstock. Though breeding for wine quality seems to have occupied a great proportion of his effort, his work on rootstock development had the greatest impact on viticulture. This work provided European grape growers with phylloxera-resistant rootstocks, allowing them to recover from the devastating epidemic of the late 19th century while still growing the ancient Vitis vinifera cultivars.

Cultivation is easy with full sun, very well-drained soil, and attention to the natural rainfall of the particular species' habitat. The more popular species from the eastern areas, such as Titanopsis calcarea, fulleri and luederitzii are adapted to summer rainfall, while those from further west, rarer species such as Titanopsis schwantesii and hugo-schlecteri, are adapted to winter rainfall, when they also flower. The plants are calcicole (=they appreciate calcareous soils), but any typical loose succulent soil mix is suitable. Division of larger clumps is possible in some cases, but as most species have tuberous rootstocks and offset slowly, seed production is the most common method of propagation.

The vine's drought resistance is dependent on the type of rootstock it is planted on but on all types of rootstocks, Grenache seems to respond favorably to some degree of moisture stress. Grenache prefers hot, dry soils that are well drained but it is relatively adaptable to all vineyard soil types. In southern France, Grenache thrives on schist and granite soils and has responded well to the stony soil of Châteauneuf-du-Pape with the area's galets roulés, heat-retentive stones. In Priorat, the crumbly schist soil of the region retains enough water to allow producers to avoid irrigation in the dry wine region.

Krymsk is known for its experimental plant-breeding station, which holds important scientific collections of, among other crops, green peas, sweetcorn, tomatoes, peppers, aubergines (eggplants), cucumbers, apples, plums, peaches, pears, apricots, and strawberries. The station's stone fruit and quince collections are the largest and most important in Russia or any part of the former Soviet Union. Of the 9,000 accessions of Prunus, about 5,000 to 6,000 are wild species and forms, 500 to 1,000 local varieties, and 2,000 to 3,000 cultivars and breeding materials. The station is also known for the creation of fruit-tree rootstocks, which are named after the town + a number (e.g.

Until the 1970s, cherries were grown on the vigorous "Malling F12/1", "Mazzard" (Prunus avium), or "Maheleb" (P. maheleb) rootstocks, which required much space and time before cropping began, thus the growing of cherries was not a realistic option on a garden scale. The introduction of the rootstock "Colt" enabled trees reaching a maximum height of to be grown, and if trained as a pyramid it is possible to restrict growth to about .Hessayon, Dr. D. G., The Fruit Expert, Transworld Publishers Ltd, 1997, p37 The popular sweet variety "Stella" can even be successfully grown in a pot on the patio when grafted onto a "Colt" rootstock.

Water and nutrient uptake of grafted tomato plants grown under saline conditions. Journal of Plant Physiology 159 (8):899-905 Many of the most economically important vegetable crops like tomato, squash, cucumber, and watermelon are highly sensitive to thermal stress in the roots throughout vegetative development and reproduction. Whether using rootstock tolerant of hot or cold temperatures, the use of temperature tolerant rootstocks often leads to the extension of the growing season in either direction, resulting in better yield and economic stability through the year.[2] Although the vegetable grafting is typically associated with reduction of disease or abiotic stress, yield is often increased without the presence of these identified sources of stress.

Paeonia mairei is a perennial herbaceous plant of up to 1 m high, that dies down in the autumn, and overwinters with buds just under the surface of the soil. It has thick roots that become thinner towards their tips, while the rootstocks is approximately 2 cm in diameter. Young shoots and leaves are initially red-purple to pink. The stems and leaves are hairless. The largest leaves, near the base of the stem are split into three, which parts themselves are split into leaflets, some of which may be incised, up to nineteen in total, 6—16½ × 1¾—7 cm, gradually broadening at their base and usually pointy at their tip.

A study in southeastern Australia found that P. spinescens does not have a viable long-lived seed bank in floodplain soil , presumably regenerating from vegetative propagules and rootstocks . In the Murray-Darling Basin, prior to regulation of the Murray River, extensive Pseudoraphis spinescens dominated floodplain marshes existed in areas that were typically seasonally flooded for 5-9 months duration in most years, to a minimum water depth of 0.5 m, and completely dry during late summer and autumn . Pseudoraphis spinescens is an important species in floodplain marsh ecosystems, providing habitat and food for a range of fauna including birds , frogs , fish and insects , and key ecosystem functions such as nutrient cycling and primary productivity .

It is a cut flower crop used for fresh cutting material and sometimes used as dried material. The species has a low natural propagation rate under cultivation and is propagated by seed or by removing offsets that are generated each year from the rootstocks. The use of micropropagation protocols has been studied.A. A. Watad, M. Kochba, A. Nissim and V. Gaba, "Improvement of Aconitum napellus micropropagation by liquid culture on floating membrane rafts", Journal Plant Cell Reports, Publisher: Springer Berlin / Heidelberg, (Print) (online), Volume 14, Number 6 / March 1995, DOI 10.1007/BF00238594, pages 345–348 This species has been crossed with other Aconitums to produce attractive hybrids for garden use, including Aconitum × cammarum.

Many crossings between native North American and European varietals were created at this time. The wine produced did not correspond in any way to the established taste trends in Europe. During the early 20th century, however, some fruit from North American vines were blended with that from Vitis vinifera to enhance the "fruitiness" of the wine. After the discovery that grafting Vitis Vinifera onto native North American rootstocks was a solution to the phylloxera problem in Europe - and in order to allow European wine to regain its place in the first half of the 20th century - North American vines (like those used in "Uhudler") were forbidden under wine regulations across the European continent.

Vitis berlandieri is a species of grape native to the southern North America, primarily Texas, New Mexico and Arkansas.ibilio.org: Vitis berlandieri It is primarily known for good tolerance against soils with a high content of lime, which can cause chlorosis in many vines of American origin. Lime is a characteristic of the soils of many classical French wine regions and highly regarded vineyard sites, and many Vitis vinifera cultivars were well suited to these growing conditions. When American vines were imported to Europe as rootstocks for grafting V. vinifera on, in the wake of the Great French wine blight, it initially proved difficult to find vine species that would grow well in lime-rich soil.

Many species of fruit, e.g., fig, olive, and pomegranate, are commonly grown on their own roots, as there may be no great advantages to using a special rootstock, or suitable rootstocks may not be readily available. However, even for fruit trees that usually are grown grafted on a rootstock, there can be advantages in growing them on their own roots instead, particularly in the traditional coppicing systems advocated in both sustainable agriculture and permaculture. Disadvantages of using own-root trees can include excessive size and excessive production of wood (thus very long times until the start of fruit production), although training branches horizontally and limiting pruning to summer only may help encourage fruit production at an earlier age.

Even in the case when a triploid plant can produce a seed (apples are an example), it occurs infrequently, and seedlings rarely survive. Because apples do not breed true when planted as seeds, although cuttings can take root and breed true, and may live for a century, grafting is usually used. The rootstock used for the bottom of the graft can be selected to produce trees of a large variety of sizes, as well as changing the winter hardiness, insect and disease resistance, and soil preference of the resulting tree. Dwarf rootstocks can be used to produce very small trees (less than high at maturity), which bear fruit many years earlier in their life cycle than full size trees, and are easier to harvest.

The Cheyenne give dried leaves to horses for urinary troubles and for a sore mouth.Hart, Jeffrey A., 1981, The Ethnobotany of the Northern Cheyenne Indians of Montana, Journal of Ethnopharmacology 4:1-55, page 6 The Klamath use the rootstocks as food.Coville, Frederick V., 1897, Notes On The Plants Used By The Klamath Indians Of Oregon., Contributions from the U.S. National Herbarium 5(2):87-110, page 90 The Menominee string the dried, boiled, sliced potatoes together for winter use.Smith, Huron H., 1923, Ethnobotany of the Menomini Indians, Bulletin of the Public Museum of the City of Milwaukee 4:1-174, page 61 The Ojibwe eat the corms for indigestion, and also as a food, eaten boiled fresh, dried or candied with maple sugar.

As both Pinot noir and Chardonnay were affected on the hill of Corton, one long lasting result of this vintage is that the cépage of many lieu-dits on the hill changed with some producers replanting their previously Chardonnay vineyards with Pinot noir to make Corton AOC and vice versa. Also many new clones and rootstocks were introduced. Beyond spring frost, the other viticulture hazard that growers have to worry about is court-noué (also known as roncet) which is a virus transmitted from vine to vine by nematodes that causes the vine to develop small leaves with short internode segments. This can impact a vine's ability to receive adequate foliage coverage to capture the sunlight needed to complete photosynthesis.

While investigating the species for horticultural purposes, he only found two herbarium specimens, those of Baird and Canby. (Coville apparently did not locate Kinn's West Virginia specimen, preserved at the Muhlenberg Herbarium.) Upon examination of the New Bloomfield site in 1918, he discovered the entire colony, except for one patch cut off by cultivation, was connected by roots, and that no seedlings were in evidence anywhere around the margins of the colony. Coville concluded that the plant was self-sterile and reproduced by extending rootstocks. After commercial nurserymen removed a truckload of box huckleberry from the New Bloomfield site in 1918, Coville was particularly anxious to preserve the species, as the New Bloomfield site was the only one then thought extant.

White spruce can be grafted with consistent success by using scions of current growth on thrifty 4- to 5-year-old rootstock (Nienstaedt and Teich 1972). Before greenhouse grafting, rootstocks should be potted in late spring, allowed to make seasonal growth, then subjected to a period of chilling outdoors, or for about 8 weeks in a cool room at 2 °C (Nienstaedt 1966). A method of grafting white spruce of seed-bearing age during the time of seed harvest in the fall was developed by Nienstaedt et al. (1958). Scions of white spruce of 2 ages of wood from 30- to 60-year-old trees were collected in the fall and grafted by 3 methods on potted stock to which different day-length treatments had been applied prior to grafting.

Owing to the especially favourable climate and good soil conditions on the Bergstraße, mainly dry and dryish wines of very high quality are made here. The main variety is Riesling. The biggest producer is the Bergsträßer Winzer eG cooperative, with its seat in Heppenheim, which also owns Hesse's biggest wine cellar. The Bergsträßer Staatsweingut (“state wine estate”) with its seat in Bensheim maintains the Hessischer Rebmuttergarten (“Vineyard Mother Garden”), formerly a vineyard cultivation facility whose goal was to fight the phylloxera, introduced from North America but only cropping up on the Bergstraße itself in 2005, by grafting phylloxera-proof hybrid rootstocks onto vines of nobler varieties. At the Bergsträßer Winzer eG begins the 6.9 km-long Erlebnispfad Wein und Stein (“Wine and Stone Adventure Path”), which runs through the vineyards with 30 stations.

Working with the Victorian Public Works Department, Bragato designed a model winery and cellars attached to the Rutherglen Viticultural College, which opened in 1897 on 1,000 acres of land to the south of Rutherglen. Bragato was bitterly disappointed when passed over as principal of the College. He then considered his situation intolerable when placed subordinate to a new choice of expert imported to tackle Phylloxera, the 26-year old Montpellier-trained Frenchman Raymond Dubois. By 1897 Bragato was openly claiming that “Phylloxera will never be eradicated from Victoria and that our experience will very likely be like that of France, Spain, Italy and other vine growing countries in Europe.” By this stage he had joined forces with international opinion and was an advocating the importation of Phylloxera-resistant American vines and planting on the rootstocks.

Fraxinus ornus is frequently grown as an ornamental tree in Europe north of its native range for its decorative flowers—the species is also sometimes called "flowering ash". Some cultivated specimens are grafted on rootstocks of Fraxinus excelsior, with an often very conspicuous change in the bark at the graft line to the fissured bark of the rootstock species. A sugary extract from the sap may be obtained by making a cut in the bark; this was compared in late medieval times (attested by around 1400 ADOxford English Dictionary) with the biblical manna, giving rise to the English name of the tree, and some of the vernacular names from its native area (fresno del maná in Spanish, frassino da manna in Italian). In fact, the sugar mannose and the sugar alcohol mannitol both derive their names from the extract.

Other causes of coulure may be vineyard conditions and practices, pruning too early or too severely, excessively fertile soils or overuse of fertilizers, and improper selection of rootstocks or clones.J. Robinson (ed) "The Oxford Companion to Wine" Third Edition pg 207-208 Oxford University Press 2006 During the flowering part of the growing season (May-June in the Northern Hemisphere, November-December in the Southern Hemisphere), grapevines often need dry conditions with sufficient sunlight and ambient air temperature around for pollination to go smoothly. Less ideal conditions, particularly wet, rainy weather, increases the odds that a higher than normal numbers of flowers go unpollinated and coulure to occur.Wine & Spirits Education Trust "Wine and Spirits: Understanding Wine Quality" pg 25, Second Revised Edition (2012), London, Coulure is a distinct phenomena unrelated to another viticultural hazard, millerandage, where the flowers are pollinated but the resulting berries develop with seeds and remain small.

The first grafts in the early 20th century were made in order to diminish attacks by infectious organisms, such as Fusarium oxysporum on watermelons. [2] However, research has shown that this technique can be effective against a variety of fungal, bacterial, viral, and nematode diseases.King, S. R., Davis, A. R., Liu, W. G., and Levi, A. 2008. Grafting for disease resistance. HortScience. Pg 1673-1676 Furthermore, many researchers are looking to utilize specific rootstocks as an alternative to methyl bromide-a soil fumigant that has been widely used until recently.[4] Grafting has been highly effective at overcoming abiotic sources of stress, such as soil salinity, temperature extremes, and excessive soil moisture.[2] Grafting has also been utilized to reduce the effects of flooding in areas where a wet season may occur.Black, L.L., D.L. Wu, J.F. Wang, T. Kalb, D. Abbass, and J.H. Chen.

In addition to propagating trees on rootstocks designed to control size/vigour and confer disease resistance, grafting above the rootstock can be used to provide multiple cultivars of a single species, known as a family tree, or, within certain limits, cultivars of different fruit species on one tree, often known as a fruit salad tree. Family trees typically combine several cultivars (two or three being most common) of apple, pear or a given species of stonefruit on a single rootstock, while fruit salad trees typically carry two or more different species from within a given genus, such as plum, apricot, and peach or mandarin orange, lemon, and lime. Certain combinations, including sour cherry (prunus cerasus)/sweet cherry (prunus avium), although from the same genus, are known to be difficult, although successes have sometimes been reported. Other grafts of this kind can produce the Pomato.
