(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.
(b) The lower portion of the graft, i.e. the stem with roots is termed as a stock. The upper portion of the graft, i.e. the stem without roots is termed as a scion.
(c) In grafting, two plants of the desired traits are chosen. First, the plant that is chosen as a scion is cut in slantingly, then the stock is also cut in the same manner. After that, the scion is placed over the stock and tightly fitted together. Either they are tied by a piece of cloth or covered using a polythene sheet
(d) Apple and orange trees are propagated by the method of grafting.
(e) The first advantage of this method of propagation is that plants with desired characteristics are obtained. Also, with this method, young stems can be made to flower and bear fruits quickly.
(f) In the cutting method, only one plant is involved, and the new plant is identical to its parent. Whereas in grafting, two plants are involved, and the new plant is completely different from its parents
