Detailed explanation-1: -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. As the fruit matures, ethylene is produced as a signal to induce fruit ripening.

Detailed explanation-2: -Too high a temperature destroys enzymes, and too low a temperature can break down the cell walls of the fruit so the contents mix and the fruit oxidizes, browns and softens abnormally. The optimum temperature and humidity conditions for ripening are 62 to 68 degrees Fahrenheit and 90 to 95 percent relative humidity.

Detailed explanation-3: -Ethylene causes ripening of fruits. Auxin is responsible for the growth of shoots.

Detailed explanation-4: -Most fruits produce a gaseous compound called ethylene that starts the ripening process.
