Gibberellin is suitable for the following crops: cotton, tomato, potato, fruit tree, rice, wheat, soybean, tobacco, etc., to promote their growth, germination, flowering and fruiting; It can stimulate the fruit growth, improve the seed setting rate, and significantly increase the yield of cotton, vegetables, melons and fruits, rice, green manure, etc.

The most prominent physiological effect of gibberellin is to promote stem elongation and induce long day plants to bolt and blossom under short day conditions. Different plants have different sensitivity to gibberellin. Genetically, dwarf plants such as dwarf maize and pea are most sensitive to gibberellin, and their plant types are similar to those of non dwarf plants after gibberellin treatment; Non dwarf plants have only slight reactions.
