Ethylene is also called ripening hormone because its basic function is ripening. Fully developed fruits, such as bananas, apples, oranges and pears, can synthesize ethylene and promote its maturity and coloring.
Ethylene, also known as phytohormone, widely exists in various tissues and organs of plants and is transformed from methionine under the condition of adequate oxygen supply. Its production has a "self-promoting effect", that is, the accumulation of ethylene can stimulate more ethylene production. Ethylene can promote the synthesis of RNA and protein in higher plants, increase the permeability of cell membrane and accelerate respiration.
By taking advantage of this, we can put immature fruits and fully mature fruits together, and let the ethylene released by fully mature fruits help the immature fruits mature as soon as possible.
