Ripening - Wikipedia, the free encyclopedia
Ripening is a process in fruits that causes them to become more edible. In general, a fruit becomes sweeter, less green, and softer as it ripens. However the acidity as well as sweetness rises during...

Ethylene has many effects on plants including being responsible for the stunting of plants in high winds or when repeatedly touched. In addition, ethylene promotes fruit ripening. Like many hormones, it does so at very low concentrations.

Ethylene is a hydrocarbon gas and quite flammable and explosive at concentrations above about 3%. Remember, a non-toxic anesthetic for humans at a concentration of 85% or higher, yet as a fruit ripening hormone, ethylene gas is effective at 0.1 to 1 ppm. One part of ethylene per million parts of air that's one cupful...

Other sources of ethylene include ripening fruit, exhaust from internal combustion engines/heaters, smoke (including cigarettes), welding, rotting vegetation, natural gas leaks, and manufacturing plants of some kinds.

Putting the fruit in a loosely closed paper bag traps the ethylene gas inside and accelerates ripening. Don’t seal the bag too tightly or use a plastic bag, however—if you trap too much moisture, mold may grow.

What is the effect of ethylene on fruit ripening?; 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.
