GENERAL KNOWLEDGE

Detailed explanation-1: -Most fruits produce a gaseous compound called ethylene that starts the ripening process. In artificial ripening, this process is mimicked using chemicals. The most commonly used chemical is called ethene.It penetrates into the fruit and decomposes ethylene.

Detailed explanation-2: –Among all the hormones, ethylene is responsible for the faster ripening of the fruit because it helps in increasing the rate of respiration, change in colour, odour and taste.-Here, ethylene is produced naturally by the plants but for the artificial ripening of fruit, we use acetylene gas.

Detailed explanation-3: -Ethylene is a gaseous plant hormone that plays an important role in inducing the ripening process for many fruits, together with other hormones and signals. An unripe fruit generally has low levels of ethylene.

Detailed explanation-4: -The correct answer is acetylene. Acetylene (ethylene) is used for the artificial ripening of green fruits.
