Ethylene Gas

Ethylene is a plant hormone first in the form of gas. If the fruit is ripe oranges combined with bananas, ripe bananas are faster because oranges emit ethylene gas. The discovery of this hormone in plants first described by R. Gane in 1934.
Ethylene is a plant and cause more rapid maturation in many fruits, including bananas. Ethylene formation requires O2 and is inhibited by CO2. All parts of the plant can produce ethylene gas angiosperms. Formation mainly occurs in roots, shoot apical meristem, mode, fall flowers and ripe fruit.
Ethylene gas has an influence on growth and development, including the following.1) Ripening fruit. The traders often store the fruit in containers gassed with CO2 at the time of delivery so that the fruit longer to mature and ripen after destination. Sometimes merchants brood ripe fruit with fresh fruit that mature quickly.2) Gas ethylene inhibits flowering in many plants. However, in some plant species, ethylene stimulates flowering. For example, the mango trees and pineapples.3) Stimulate abscission (defoliation).4) Joint gibberellin determine the expression of the genital organs of plants, such as the cucumber.

What is Calcium Carbide (Carbide)?Calcium carbide or carbide is a chemical compound with chemical formula CaC2. Carbide is used in carbide welding process and also to accelerate the maturation of the fruit.Equation for Calcium Carbide with water isCaC2 + 2 H2O → C2H2 + Ca (OH) 2

Therefore 1 gram CaC2 produces acetylene 349ml. In the process of carbide welding, acetylene is then burned to generate the heat required in welding. (Wikipedia)
Ethylene gascarbide has long been used traditionally to stimulate fruit maturity. Its effectiveness is only one hundredth than ethylene. Who knew that in addition to hyper maturity, acetylene gas produced from calcium carbide is also useful to eliminate green.ConclusionSo the hormones that make ripe fruit called ethylene gas (carbide = trade name). Actually, natural plant hormones that are already producing fruit becomes ripe. But the fruit traders has added more carbide than normal levels so the fruit can mature faster.The use of calcium carbide does not cause negative impacts. Levels of vitamins and minerals does not change because of the use of this carbide. This is because the carbide is a chemical that stimulates only pembntukan stimulate ethylene gas ripening the fruit. In addition, no significant negative impact to customers in health.
