Question

A farmer while growing grape plants in his garden, observes the following:
(i) Fruit size normally remained small.
(ii) Natural seed abortion.
(iii) Reduced stem and leaf growth.
Which problems could be solved by application of gibberellic acid during the development of the fruits?
(A) (i) and (ii)
(B) (i) and (iii)
(C) (i), (ii) and (iii)
(D) None of these

Answer 1

Hint: Gibberellic acid is the one of the phytohormones that are found in the plants and the fungi. The plants have the ability to produce these hormones and it can also be produced in industries with the help of the microorganism. In agriculture they are applied for the effective yield and the growth of the crops.

Complete answer:
The gibberellic acid is the pent acyclic diterpene which helps the plants by promoting the growth of them and also elongation of the cells. This helps in the process of seed germination by the production of the hydrolytic enzymes. Since the gibberellin affects the growth of the plants, their small amount may cause huge growth in plants.

On the other hand, the large amount of this hormone may result in the opposite effect. They also promote the cell division that causes the stem and the root development. This also increases the size of the fruit. Among the given options, it is clear that the gibberellin is used to cute the reduced size of the fruit and also reduced stem and root growth.

Hence the correct answer is OPTION(B)

Note: This gibberellic acid is mainly used for the increase in the yield of citrus fruits like the grapes, lemon, orange etc. By increasing the crop yield, it also benefits the farmers by providing more profit from the cultivation. This gibberellic acid is only applied at small quantities.
