Detailed explanation-1: -Furthermore, removal of ethylene as it forms or inhibition of ethylene synthesis retards ripening (Tucker and Grierson, 1987). Fruit ripening induced by ethylene treatment is similar biochemically to natural ripening.
Detailed explanation-2: -Ethylene gas is commercially used to ripen fruits after they have been picked. Fruits, such as tomato, banana, and pear are harvested just before ripening has started (typically in a hard, green, but mature stage).
Detailed explanation-3: -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.
