Detailed explanation-2: -In grafting, the upper part (scion) of one plant grows on the root system (rootstock) of another plant.

Detailed explanation-3: -A scion is a piece of vegetative material that you will graft with, from a tree that produces the fruit variety you want. For grafting like whip and tongue, scions are collected in the winter when the trees are dormant.

Detailed explanation-4: -The scion is the top part of the grafted plant and is a piece of a shoot with wood, bark, and dormant buds, which will produce the stem and branches.

Detailed explanation-5: -Grafting is the act of placing a portion of one plant (bud or scion) into or on a stem, root, or branch of another (stock) in such a way that a union will be formed and the partners will continue to grow. The part of the combination that provides the root is called the stock; the added piece is called the scion.
