T budding

Shield budding, also known as T-budding, is a technique of grafting to change varieties of fruit trees. Typically used in fruit tree propagation, it can also be used for many other kinds of nursery stock. [1] An extremely sharp knife is necessary; specialty budding knives are on the market. A budding knife is a small knife with a type of spatula at the other end of the handle. [2] 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.[ citation needed ]

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. 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.[ citation needed ]

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. The buds are in the leaf axils. They may be so tiny as to be almost unnoticeable.[ citation needed ]

Holding the petiole of the leaf as a handle, an oval of the main stem is sliced off, including the petiole and the bud. This is immediately slid into the T on the rootstock, before it can dry out. The joined bud and rootstock are held by a winding of rubber band, which will hold it until sealed, but the band will deteriorate in the sunlight so it soon breaks and does not pinch new growth, girdling the shoot.[ citation needed ]

The percentage of "take" of the buds depends on the natural compatibility of the stock and scion, the sharpness of the knife, and the skill of the budder; even the experts will have some buds die.[ citation needed ]

Fruit tree propagation

Fruit tree propagation is usually carried out vegetatively (non-sexually) by grafting or budding a desired variety onto a suitable rootstock.

Fruit tree pruning

Fruit tree pruning is the cutting and removing of selected parts of a fruit tree. It spans a number of horticultural techniques. Pruning often means cutting branches back, sometimes removing smaller limbs entirely. It may also mean removal of young shoots, buds, and leaves.

Gall Abnormal growths especially on plants induced by parasitic insects and other organisms

Galls or cecidia are a kind of swelling growth on the external tissues of plants, fungi, or animals. Plant galls are abnormal outgrowths of plant tissues, similar to benign tumors or warts in animals. They can be caused by various parasites, from viruses, fungi and bacteria, to other plants, insects and mites. Plant galls are often highly organized structures so that the cause of the gall can often be determined without the actual agent being identified. This applies particularly to some insect and mite plant galls. The study of plant galls is known as cecidology.

Pomelo Citrus fruit

The pomelo, pummelo, or in scientific terms Citrus maxima or Citrus grandis, is the largest citrus fruit from the family Rutaceae and the principal ancestor of the grapefruit. It is a natural, i.e., non-hybrid, citrus fruit, native to Southeast Asia. Similar in taste to a sweet grapefruit, the pomelo is commonly consumed and used for festive occasions throughout Southeast Asia.

Cider apples are a group of apple cultivars grown for their use in the production of cider. Cider apples are distinguished from "cookers" and "eaters", or dessert apples, by their bitterness or dryness of flavour, qualities which make the fruit unpalatable but can be useful in cidermaking. Some apples are considered to occupy more than one category.

Carpinus caroliniana, the American hornbeam, is a small hardwood tree in the genus Carpinus. American hornbeam is also known as blue-beech, and musclewood. It is native to eastern North America, from Minnesota and southern Ontario east to Maine, and south to eastern Texas and northern Florida. It also grows in Canada.

<i>Ricinodendron</i>

Ricinodendron is a plant genus in the family Euphorbiaceae first described as a genus in 1864. It includes only one known species, Ricinodendron heudelotii, native to tropical Africa from Senegal + Liberia east to Sudan and Tanzania and south to Mozambique and Angola. It produces an economically important oilseed. The tree is known as munguella (Angola), njangsa (Cameroon), bofeko (Zaire), wama (Ghana), okhuen (Nigeria), kishongo (Uganda), akpi, djansang, essang, ezezang and njasang. Two varieties of the tree species are recognized R. heudelotii var. heudelotii in Ghana and R. heudelotii var. africanum in Nigeria and westwards.

A rootstock is part of a plant, often an underground part, from which new above-ground growth can be produced. It could also be described as a stem with a well developed root system, to which a bud from another plant is grafted. It can refer to a rhizome or underground stem. In grafting, it refers to a plant, sometimes just a stump, which already has an established, healthy root system, onto which a cutting or a bud from another plant is grafted. In some cases, such as vines of grapes and other berries, cuttings may be used for rootstocks, the roots being established in nursery conditions before planting them out. The plant part grafted onto the rootstock is usually called the scion. The scion is the plant that has the properties that propagator desires above ground, including the photosynthetic activity and the fruit or decorative properties. The rootstock is selected for its interaction with the soil, providing the roots and the stem to support the new plant, obtaining the necessary soil water and minerals, and resisting the relevant pests and diseases. After a few weeks the tissues of the two parts will have grown together, eventually forming a single plant. After some years it may be difficult to detect the site of the graft although the product always contains the components of two genetically different plants.

Grafting

Grafting or graftage is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together and such joining is called inosculation. The technique is most commonly used in asexual propagation of commercially grown plants for the horticultural and agricultural trades.

Harrison Cider Apple

The Harrison cider apple is one of the most famous 18th-century American cider apples, primarily used for the production of apple cider. Grown in New Jersey before and after the American Revolution, it became obsolete by the 20th century. The Harrison cider apple was considered lost until it was recovered in Livingston, New Jersey at an old cider mill in September 1976.

<i>Prunus avium</i> Species of flowering plant in the rose family Rosaceae

Prunus avium, commonly called wild cherry, sweet cherry, gean, or bird cherry is a species of cherry, a flowering plant in the rose family, Rosaceae. It is native to Europe, Anatolia, Maghreb, and Western Asia, from the British Isles south to Morocco and Tunisia, north to the Trondheimsfjord region in Norway and east to the Caucasus and northern Iran, with a small isolated population in the western Himalaya. The species is widely cultivated in other regions and has become naturalized in North America and Australia.

Propagation of grapevines

The propagation of grapevines is an important consideration in commercial viticulture and winemaking. Grapevines, most of which belong to the Vitis vinifera family, produce one crop of fruit each growing season with a limited life span for individual vines. While some centenarian old vine examples of grape varieties exist, most grapevines are between the ages of 10 and 30 years. As vineyard owners seek to replant their vines, a number of techniques are available which may include planting a new cutting that has been selected by either clonal or mass (massal) selection. Vines can also be propagated by grafting a new plant vine upon existing rootstock or by layering one of the canes of an existing vine into the ground next to the vine and severing the connection when the new vine develops its own root system.

Mtevandidi is an indigenous red grape variety from the region of Guria in the country of Georgia, primarily used for producing table wine. It is known also by the synonyms Akido, Achido, Didd Mtevana, Didmtevana, and Didtevano. There are no written sources regarding the origin of Mtevandidi. Botanical and agricultural features suggest that this variety is indigenous to Georgia.

Nurse grafting is a method of plant propagation that is used for hard-to-root plant material. If a desirable selection cannot be grown from seed, because it will be genetically different from the parent, it must be propagated asexually in order to be genetically identical to the parent. Nurse grafting results in a scion developing its own roots, instead of being grafted to a rootstock.
