ethylene gas


Ethylene is a growth hormone that is produced from normal metabolism in plants. Role of ethylene in fruit ripening and loss daun.Dalam fruit ripening, ethylene working to solve the chlorophyll in young fruit, so the fruit has only xantofil and carotene. Thus, the color becomes orange or red fruit

Ethylene is a growth hormone that is produced from normal metabolism in plants. Role of ethylene in fruit ripening and leaf loss. Ethylene is also called ethane. Additionally Ethylene (IUPAC name: ethene) is an organic compound, a hydrocarbon with the formula C2H 4 or H2C = CH2. It is a colorless flammable gas with a faint "sweet and musky smell" when pure. [3] It is the simplest alkene (hydrocarbons with carbon-carbon double bonds), and the simplest unsaturated hydrocarbons after acetylene (C2H 2).
Hormone Ethylene Gas is a gaseous hormone in plant life active in ripening fruit. Applications containing Ethephon, the synthetic Ethylene optimal performance so that goals can be achieved pieces cook faster. (eg: Etephon, Protephon) trademarks include: Prothephon 480SL. Ethylene gas is found in many old fruit.

As the influence of ethylene activity, namely:

 Temperature. High temperature (> 350C) ethylene formation does not occur. The optimum temperature of formation of ethylene (tomatoes, apples) 320C, while for the other fruits lower.

Mechanical wounding and infection. Fruit broken, bruised, and a nest of caterpillars eat

 radioactive rays

 Presence of O2 and CO2. When O2 is lowered and elevated CO2 inhibited the maturation process. And if the situation does not occur anaerobically ethylene formation

The interaction with the hormone auxin. If the concentration of auxin increases, ethylene will increase

 The level of maturity

  1. The process of fruit ripening is often associated with a series of changes that can be seen meluputi color, aroma, konsisitensi, and flavor and aroma. The combination of these attributes will contribute to the possibility of the fruit good to eat. But with the rapid pace of ripening fruit, the fruit is also fast towards destruction or decay.
