Molecular Structure:
 
Application: Gibberellins(GA3) belong to a natural plant hormone. It can stimulate plant stem elongation by stimulating cell division and elongation. And it can break seed dormancy, promote  gerimination, increase  fruit  setting  rate,  or  cause  parthenocarpic (seedless) fruit by stimulating stems of a plant higher and leaves bigger. Then, it has been proved from production  practice for many years that the appliation of gibberellin has signification effect in raising the yield of rice, wheat, corn, vegetable, fruit, etc.


Assay:TECH is divided into high-grade products (GA390%), EC4000g/mL.
Appearance: TECH is white to yellowish crystal powder. EC is a brown transparent clear liquid
Melting point:  223-225. 
Solubility: It is soluble in organic solvents such as alcohols, acetone, ethyl acetate and buffer solution of pH6.2 Phosphoric acid.  Solvency in water is 5g/L. EC is easy flammable, and soluble in water.
Stability: The product is quite stable in dry state and acid solution. It can easily resolve when basic is added.
Toxicity: Ld50 of intravenous injection for rats is 6.3g/kg. No carcinogenic, tertogenic, mutagenic effect.
Package: 25kg/drum or small packaging of plastic bags.
Storage: Store in below 50, dry place and shelter from light. Avoid mixing with basic material while using gibberellins. EC should be far away from the fire.
