Ethylene is a growth hormone produced from the result of normal metabolism in plants. Ethylene plays a role in fruit ripening and leaf loss. Ethylene is also called ethene. Ethylene compounds in plants are found in the gas phase, so called ethylene gas. Ethylene gas is colorless and volatile
Ethylene has a fairly simple structure and is produced in higher plants.

Ethylene is often used by our distributors and importers of fruit. The fruit is packaged in a not yet ripe when the fruit traders transported. Having arrived for trade, fruit is given ethylene (brooded) so quick to cook.
In fruit ripening, ethylene acts by breaking chlorophyll in young fruit, making fruit has only xantofil and carotene. Thus, the color becomes orange or red fruit

If the concentration of ethylene dangat higher than hormones auxin and gibberellin, ethylene can inhibit the formation of stems, roots, and flowers. However, ethylene also can stimulate the formation of interest when, together with the hormone auxin

experienced during the ripening of fruit, then the existing network in the fruit increased ethylene gas production ...
ethylene gas is able to solve the chlorophyll in the young fruit until the fruit has only resulted in xantofil and xarotein or substance that makes skin becomes red or orange fruit. because chlorophyll has been reduced by ethylene gas ....
