Question

The diameter of the stock is more than scion in
A. Tongue grafting
B. Wedge grafting
C. Crown grafting
D. Approach-grafting

Answer 1

Hint: Grafting is a process in which the parts of two different plants are fused together to form a new plant. Moreover, in crown grafting, several stems of small diameter are fused with a root of greater diameter.

Complete step by step answer: Let us look at all the options that are given to us one by one.
-Tongue grafting: It is the simplest type of grafting. In tongue grafting, the stock and scion are cut obliquely. This is because if they are cut horizontally and placed together then they wouldn’t fit properly and would be less stable. The diameter of the stock and the scion is the same.
-Wedge grafting: Wedge grafting is the grafting in which the scion is cut in a conical shape and then fitted into the stock. The diameters of the stock and the scion could be different or can be the same in wedge grafting. If the diameters are different then the diameter of the scion is less than the diameter of the stock.
-Crown grafting: Crown grafting is the grafting in which the diameter of the stock is always greater than the diameter of the scion. Here the branches are different but the root is the same. Crown grafting helps in developing one single plant with several varieties.
-Approach-grafting: Approach-grafting is the grafting with the mobile stock. The branch of the stock is cut below the grafting point. Above the grafting point, the scion is cut.
Thus, based on the above information, we can conclude that the diameter of the stock is more than scion in Crown grafting.
Hence, the correct answer is option (C).

Note: Grafting is the process in which the parts of two different plants are fused together to form a new composite plant. The plant from which the roots are taken is known as the stock. It is the plant in which the characters are to be imbibed. The plant from which the stems are taken is known as the scion. It is the plant from which the characters are to be imbibed.
