Detailed explanation-1: -Grafting and budding are horticultural techniques used to join parts from two or more plants so that they appear to grow as a single plant. In grafting, the upper part (scion) of one plant grows on the root system (rootstock) of another plant. In the budding process, a bud is taken from one plant and grown on another.

Detailed explanation-2: -Plant grafting is a vegetative propagation technique that connects two severed plant segments together. The chimera, consisting of the scion and rootstock, survives as a new individual after wound healing.

Detailed explanation-3: -Plants of the same botanical genus and species can usually be grafted even though they are a different variety. Plants with the same genus but of a different species often can be grafted. But the result may be weak or short-lived, or they may not unite at all.

Detailed explanation-4: -(a) Grafting is a method of artificial propagation in which the stem of two plants are cut, one with and the other without roots. These stems are then joined together to form a single plant.

Detailed explanation-5: -Grafting is a process in which a portion of one plant part is placed (known as scion) onto a portion of another plant (known as stock). It is the artificial method of vegetative propagation. Apple reproduces vegetatively through root grafting.
