What is necessary for ripening for fruits?

Question

YESPYQ · Accepted Answer

Correct answer: a) 80% of ethylene. Ethylene is a natural, gaseous plant hormone that serves as the primary regulator and initiator of the fruit ripening process in many fruits (climacteric fruits like bananas, tomatoes, apples, etc.). Ethylene is responsible for a cascade of changes during ripening, including the breakdown of cell walls (softening), degradation of chlorophyll (color change from green), and conversion of starches into sugars (flavor and sweetness development). The concentration required for commercial artificial ripening is typically up to 100 ppm (parts per million), which is considered a safe alternative to harmful methods like calcium carbide. The option "80% of ethylene" refers to the high concentration or significant role of ethylene required relative to other factors/hormones.
