Gibberellic(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.
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.
Common name: Gibberellic acid, GA3 Chemical name: 2, 4A, 7-trihydroxy-1-methyl-8-methyle negibb-3-ene-1, 10-carboxylic acid-1, 4A-lactone Formula: C19H22O6 C A S Number: [77-06-5] Specification: 90% TECH
Molecular formula: C19H22O6 Appearance: White or buff crystal powder Solubility: Easily dissolve in ethanol, acetone. Slightly dissolve in water (5g/L)or chloroform.
Stability: GA3 is high stable in acidic solution or litmusless solution. Rapidly break down in alkali solution. Rapidly decomposed by heat. Melting point: 223-225. Shelf life: 3 years under the cool, shade and dry storage conditions. Toxicity: Small rat can resist LD50 15000mg/kg.
Use: Break dormancy; Promote bourgeon; Improve quality and increase fruit production. Applicable to fruits and vegetables.
Cautions: 1. Due to low solubility of the pure gibberellic acid in water, dissolve it in small amount of ethyl alcohol at first, add water to reach the concentration required. 2. Must avoid being used with alkaline substance; May be used with neutral or mild acidic. 3. The product must be stored in low temperature and dry conditions. Should be used immediately after adding water.
