Question

If the scion of a sweet and fleshy plant is grafted with a stock of sour and plant, then the fruit will be
A. Sweet and fibrous
B. Sweet and fleshy
C. Sour and fleshy
D. Sour and fibrous

Answer 1

Hint: Grafting is a technique that joins two plants into one. Basically, a wound is created on one of the plants, and the other is inserted into that wound so each plant's tissues can grow together. Most fruit trees today are grafted onto the rootstock. This is a type of vegetative propagation that comes in the category of asexual reproduction.

Complete answer: Asexual reproduction: It is a type of reproduction in which offspring are produced by a single parent with or without the involvement of gametes.
Vegetative propagation is a type of asexual mode of reproduction in which vegetative parts of plants give rise to the new plant.
A type of vegetative propagation includes:
1. Cutting
2. Layering
3. Grafting
Grafting is a type of vegetative reproduction in which one plant is joined with the other plant. Scion is the upper part of the combined plant whereas the lower part of the combined plant in stock. For example, scions from French varieties of vines that produce superior wine grapes are grafted onto rootstocks of American varieties, which are more resistant to certain soil pathogens.
The genes of the scion determine the quality of the fruit, so the quality is not diminished by the genetic makeup of the stock. In some cases of grafting, however, the stock can alter the characteristics of the shoot system that develops from the scion. For example, if the scion of a sweet and fleshy plant is grafted with a stock of sour and plant, then the fruit will be sour and fleshy.

 So, the correct option is option C. Sour and fleshy.

Note: Advantages of grafting: precocity, dwarfing, ease of propagation, hybrid breeding, sturdiness, pest resistance, genetic consistency. Factors for a successful graft: compatibility of scion and stock, cambium alignment, and pressure, completed during the appropriate stage of the plant, proper care of the graft.
