What is Gibberellic acid ?
Gibberellic acid is a kind of plant hormone with the structure of gibberellin alkane ring which can promote plant growth.
Gibberellin mainly through the leaves, twigs, flowers, seeds or fruits into the plant body, and then conduction to the growth of active parts to play a role. Promote cell, stem elongation, leaf enlargement, single sexual setting, fruit growth, break seed body sleep, change the ratio of male and female flowers, affect the flowering time, reduce flower and fruit shedding. It is an antagonist of growth inhibitors such as paclobutrazol and acidin.

1. It can stimulate plant stem elongation by stimulating cell division and elongation. 

2. And it can break seed dormancy, promote germination, and increase fruit setting rate, or cause parthenocarpic (seedless) fruit by stimulating stems of a plant higher and leaves bigger. 

3. Then, it has been proved from production practice for many years that the application of gibberellins has signification effect in raising the yield of rice, wheat, corn, vegetable, fruit, etc.
 

Used in Artichokes, beans, celery, cotton, Fuggle hops, lettuce, oats, peas, rice, rhubarb, rye, seed potatoes,soybeans, spinach, sugarcane, tomatoes, blueberries, cherries, grapes, grapefruit, Italian prune,

lemons, navel oranges, Orlando tangelo, strawberries, and certain grasses.
