Physical and Chemical Properties

Pure product is white crystal, melting point is 233~235℃, easily soluble in alcohol, acetone, ethyl acetate, sodium bicarbonate solution and pH 6.2 phosphate buffer, insoluble in water and acetaldehyde. The aqueous solution is acidic and easily decomposed in case of alkali.

Function and Characteristics

Gibberellic acid is a broad-spectrum, highly effective plant growth regulator. It promotes cell and stem elongation, leaf expansion, parthenocarpy, fruit development, seed dormancy breaking, modification of the male-to-female flower ratio, regulation of flowering timing, and reduction of flower and fruit drop.

1. Break seed dormancy and promote germination;
2. Promote stem and leaf growth;
3. Preserve flowers and fruits or form seedless fruits; 
4. Relieve aging, keep fresh:
5. Improve seed production;
6. Promote the flowering of tombs:
7. Antagonists as inhibitors
