The gas used for artificial fruit ripening of green fruit is – (1) Ethylent (2) Acetylene (3) Ethane (4) Methane
by

1 Answer

Answer :

(1) Ethylent Explanation: Ethylene can promote ripening in tomatoes, bananas, citrus, pineapples, dates, persimmons, pears, apples, melons, mangos, avocados, papayas and jujubes - a clear indication that the action of ethylene is general and widespread amongst a number of fruits. It is clear that ethylene is a ripening hormone - a chemical substance produced by fruits with the specific biological phenomenon of accelerating the normal process of fruit maturation and senescence.
