Solution
Gibberellin increases the number and size of several fruits, e.g., grape, tomato. The hormone creates more room by increasing the size of stalks so that the fruit can grow in size. Ethophon is 2-chloroethyl phosphonic acid. In aqueous solution, ethophon slowly releases ethylene and is transported to various parts. It aids in fruit ripening in some fleshy fruits like banana, tomato, apple, mango, etc.
