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.
