The fruits can be left on the three longer using GA so as to extend the market period. This is due to which function of GA?

A

Bolting

B

Delaying senescence

C

Internodal elongation

D

Inducing parthenocarpy

Text Solution

Verified by Experts

The correct Answer is:
B
Some of the gibberellins are commercially used in the delayed ripening of fruits. `GA_(7)` delays senescence so that fruit can be left on the tree for longer period. It extends period of marketing. Ripening of Citrus fruits can be delayed with the help of gibberellins. This is useful in storing the fruits.
