Solution(By Examveda Team)

Ethylene is the chemical hormone used for degreening of citrus fruits.
Degreening is the process of removal of green colour from the skin of citrus fruit to show it is ripe and increase its market value. In this process, the measured amounts of ethylene gas are exposed to fruits under a controlled environment with specific temperatures and humidity.
