Ethephon and ethylene are literally similar. Many people don't understand what these two things are for. What is the difference? The Chinese pesticide network Xiaobian introduces ethephon and ethylene:
Ethylene is simply a plant hormone, a gas that plants can produce, and ethephon is a common plant growth regulator that mimics the former's role.
Ethylene
A simplest plant hormone synthesized in ethylene plants. The structural formula is H2C=CH2, a colorless gas that can be dissolved in water for transport in the body or diffused into the intercellular space as a gas. Widely distributed in various tissues and organs of plants. Almost all tissues have the ability or potential to produce ethylene, which can cause large changes in the rate of synthesis when external conditions (such as drought, stress, injury, etc.) and changes in cellular physiology. Its production can regulate or influence the growth and development of an individual.
Ethyl (ethrel)
A growth regulator that releases ethylene. The chemical name is 2-chloroethylphosphonic acid. The product is light yellow and viscous liquid, which is strongly acidic, soluble in water, stable below pH3, decomposes and releases ethylene at pH 4 or above, and is diluted with water to pH 4 or into the internal environment of the plant, which can gradually decompose and release ethylene. Therefore, the physiological effects of ethylene, such as ripening fruits, promoting shedding and aging, increasing emulsion excretion, promoting seed germination and controlling sex, can be replaced by them.
Ethephon is a mimicking of ethylene. Because ethylene is a gas that cannot be applied like other solutions, it uses ethephon. Of course, it is not a substance with ethylene. As a plant growth regulator, ethephon is a plant regulation. The growth agent, commonly used in the form of a liquid, releases ethylene during use, and is generally used to promote fruit ripening in order to regulate plant growth.
