Question

Grafting is the union between two plants of closely related varieties. Following are some statements regarding different types of grafting
(i) An oblique cut followed by a notch is given to both stock and scion.
(ii) Scion is a bud with a small piece of bark and cambium.
(iii) Both stock and scion are of the same diameter.
(iv) The stock has many times more diameter than Scion.
Identify the type of grafting with respect to these statements and select the correct option.

• A. (i) can be tongue grafting in which diameter of stock is larger than that of scion
• B. (ii) can be bud grafting in which stock of monocot and scion of dicot plant are usually united
• C. (iii) can be wedge grafting in which v-shaped notch is given to stock whereas wedge like cut is given to scion
• D. (iv) can be crown grafting in which many stocks are inserted in the slits made in the scions

Answer 1

The correct option is C (iii) can be wedge grafting in which v-shaped notch is given to stock whereas wedge like cut is given to scion

In the tongue grafting, an oblique cut followed by a notch is given to both the stock as well scion. The two perfectly fit upon one another, they are tied together. Stock and scion are of the same diameter. In bud grafting, the scion is a bud with a small piece of bark and cambium. Monocots do not possess cambium, thus the two plants taken can be dicots only. In wedge grafting, the V-shaped notch is given to stock while the wedge-like cut is given to Scion. Both are also of the same diameter. In crown grafting, many scions are selected and shaped at the base to form a wedge. Many slits are formed on the sides of the stock. Scions are inserted in the slits and bandaged. The stock has a large diameter than Scion.
