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 stck and scion are of same diameter. (iv) Stock has many times more diameter than scion. Identify the type of grafting with respect to these statements and select the correct option.

Answer»

can be tongue grafting in which DIAMETER of stck is larger than that of scion.
can be bud grafting in which stock of monocot and scion of dicot plant are usually united.
can be wedge grafting in which v-shaped notch is given to stock whereas wedge LIKE cut is given to scion.
can be crown grafting in which many stcks are inserted in the slits made in the scions.

Solution :In the tongue grafting, an oblique cut followed by a notch IWS given to both the stock as well scion. The two perfectly fit upon one another, they are tied together. Stock and scion are of same diameter. In bud grafting, 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,v-shaped notch is given to stock while wedge like cut is given to scion. both of same diameter, in crown grafting, many6 scions are selected and shaped at the base to form wedge. Many slits are formed on the sides of stock. Scions are inserted in the slits and bandaged. Stock has large diameter diameter than scion.
