WebApr 8, 2024 · Grafting is a specialized type of plant propagation where part of one plant (the scion) is inserted into another (the rootstock or stock) in such a way that they unite and grow as a single plant. Budding is a type of grafting, with the scion consisting of a single bud attached to a piece of bark and sometimes a thin sliver of wood underneath.

WebMar 6, 2024 · Grafting is a horticultural practice used for many purposes. In this, a shoot (scion) or bud isolated from one plant is joined to the rooted part (stock) of another plant, the union of two produces one plant. If either scion or stock contains the virus, the whole plant established through grafting also contains the virus.
