Grafting or graftage [1] 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 (/ ˈ s aɪ ə n /) while the lower part is called the rootstock. The success of this joining requires that the vascular tissues grow together.
The scion, taken from dormant wood of the previous season's growth, is cut to a wedge shape at the end and inserted into the cut between the cotyledons, so that the cambium surfaces of each can join. The grafted plant is then set in a rooting medium with the union about 1.5 inch below the surface. [1]
When the scion or propagule grows in the same branchlike way, it is called plagiotropic growth. [2] Orthotropic growth is when the scion begins to grow in the same upward manner as the ortet. [ 2 ] The duration of plagiotropic growth habit depends on the tree species and developmental stage (whether bud or scion) when cut, before the ramet ...
The complementary notches are fit together and held with a spring clip or some type of tape. Once the graft union has healed, the root system is cut from the scion plant and the shoot is removed from the rootstock plant [12]. Cleft grafting is carried out when the plants are slightly larger, and a V-shaped cut is made in the stem of the scion ...
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 ...

AxR1 is a grape rootstock once widely used in California viticulture.Its name is an abbreviation for "Aramon Rupestris Ganzin No. 1", which in turn is based on its parentage: a cross (made by a French grape hybridizer named Ganzin) between Aramon, a Vitis vinifera cultivar, and Rupestris, an American grape species, Vitis rupestris—also used on its own as rootstock, "Rupestris St. George" or ...
