Question

A scion is grafted to a stock. The quality of fruits produced will be determined by the genotype of
A) Stock
B) Scion
C) Both A and B
D) None of the above

Answer 1

Stock and Scion are mainly used in the technique of grafting, wherein this technique different tissues of the different plants are joined together and make them grow to continue together, in this process the upper part of the combined plant is called as scion and the other part which is lower part is called as stock.

Complete answer:
Grafting is the technique where the two parts of the plants combine to grow each other, and in this method, one plant is selected for their roots and that one is called as stock or rootstock, while some other plants are selected for their stems, leaves or flowers and it is called as Scion.
And this Stock and Scion is also used in culture techniques, while they are used in grafting both of them are joined in such a way that both of the vascular tissues get joined together.
And this technique is also commonly used in case of asexual reproduction or vegetative propagation, and in grafting both of the tissues are kept alive.
As we know that Scion is nothing but the vegetative parts of the plants, while Stock is nothing but roots, so roots are helpful for transfer of water and nutrients, but the propagation is occurred by the vegetative parts so that the quality of fruits produced by the genotype is determined by the Scion.

The correct option is B.

Note: Stock and Scion are nothing but the parts of the plants which are used in different agriculture and horticulture techniques where Stock is the roots of the plants and its role is to transfer water and nutrients, and Scion is vegetative parts of plants, where they play a role in propagation.
