Detailed explanation-1: -Abscisic acid (ABA) and ethylene are the major regulators of ripening and senescence in both dry and fleshy fruits, as demonstrated by numerous ripening-defective mutants, effects of exogenous hormone application, and transcriptome analyses.
Detailed explanation-2: -Ethylene is an important plant hormone. In bananas and many other fruits, production of ethylene surges when the fruit is ready to ripen. This surge triggers the transformation of a hard, green, dull fruit into a tender, gaudy, sweet thing that’s ready-to-eat.
Detailed explanation-3: -Ethylene is a gas and is known as the “fruit-ripening hormone.” Every fruit has a certain level of ethylene production throughout its lifecycle. However, in some fruits, ethylene levels shoot up when the fruit starts ripening.
