Grafting

Q.

Give an example of a plant which is produce by grafting method.

Q. 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.

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