Ethephon

Ethephon, organic compounds, refinement to white needle crystal, industrial products is light brown liquid, soluble in water, methanol, acetone, ethylene glycol, propylene glycol, slightly soluble in toluene, insoluble in petroleum ether. Used for agricultural plant growth stimulator. Ethephon is quality and efficient plant growth regulator, have promote fruit mature, stimulate bleeding, regulating gender transformation effect, etc.

The physical and chemical properties editor

A crystalline solid, melting point 74 ℃ ~ 75 ℃, boiling point is about 265 ℃ (decomposition), density 1. 409 + 0.02 g/cm3 (20 ℃, technical). The water solubility of about LKG/L (23 ℃), soluble in ethanol, methanol, isopropyl alcohol, acetone, ethyl acetate and other organic solvent polarity, slightly soluble in non-polar organic solvent such as benzene, toluene, insoluble in kerosene, diesel oil. When pH < 3.5 in aqueous solution, stability, increased with pH hydrolytic release ethylene. Sensitive to uv light, stable below 75 ℃.

Chemical properties editor

Stable at room temperature under normal pressure, avoid the material: oxide alkali water/moisture, has irritating to the skin, eyes, mucous membrane, no teratogenic, carcinogenic and mutagenic effects.

Mechanisms of editing

Ethephon with ethylene is the same, mainly is the ability to enhance cell RNA synthesis, promote protein synthesis. Abscission zone in plants such as base of petiole, peduncle, petals, because of increased protein synthesis, prompted in abscission layer to cellulose enzyme synthesis, for speeding up the abscission layer formation, leading to organ prolapse. Ethephon can enhance the activity of the enzyme, still can activate when ripe phosphatase and other related to fruit mature enzyme, promoting the fruit mature. In the aging or infected plants, because ethrel promote protein synthesis and cause the change of peroxidase (pod). Ethylene can inhibit the synthesis of endogenous auxin, slow the growth of plants.

Main use edit

Ethephon plant growth regulator, is a plant hormone increase emulsion secretion, accelerate mature, fall off, and promote flowering physiological effects of aging. Under certain conditions, ethephon itself can not only release ethylene, but also can induce plants to produce ethylene.

Used for agricultural plant growth stimulator. Ethephon (ethephon) is a quality and efficient plant growth regulator, a ethephon can release molecules of ethylene, is promoting the fruit mature, stimulate bleeding, regulating gender transformation effect, etc.
