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 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.
Detailed explanation-3: -Ethylene plays a vital role in the natural ripening of fruits. It is a hormone produced naturally within the fruits to stimulate ripening process.
Detailed explanation-4: -Ethylene is regarded as a multifunctional phytohormone that regulates both growth, and senescence. It promotes or inhibits growth and senescence processes depending on its concentration, timing of application, and the plant species.
Detailed explanation-5: -Complete answer: Ethylene is a hormone responsible for fruit ripening. Ethylene is a gaseous plant hormone.
