Q. Gibberellic acid has been successfully used to induce flowering

NTA AbhyasNTA Abhyas 2022

Solution:

Gibberellins produce a wide range of physiological responses in the plants. Their ability to cause an increase in length of axis is used to increase the length of grapes stalks. Gibberellins, cause fruits like apple to elongate and improve its shape. They also delay senescence. Thus, the fruits can be left on the tree longer so as to extend the market period. Gibberellins also replace the long day requirement for flowering.
