Grafting
A method of plant propagation widely used in horticulture, where the tissues of one woody plant (tree, shrub) are affixed to those of another.Most commonly, the shoot also known as the scion of a selected, desired plant cultivar is grafted onto another, known as the rootstock, in order to reproduce the exact characters of the desired plant. The rootstock can be a seedling-grown plant or a clone itself.
Grafting can only be done between reasonably closely related plants. Most often the limits of success are with other species in the same genus, though in some cases plants in different but closely related genera can graft successfully (e.g. Larch will graft on Douglas-fir), and in other cases, not, even between some species in the same genus (e.g., Norway maple will not graft on Sugar maple).
A curiosity sometimes done by gardeners is to graft related potatos and tomatos so that both are produced on the same plant, one aboveground and one underground.
Similarly, grafting can also refer to harvesting tissue from another part of an animal or human's body in order to replace a part that is damaged. It is usually done with skin. (See medical grafting)
