Chlormequat chloride (CCC) is an antagonist of gibberellins.Its main function is to inhibit the biosynthesis of gibberellins.It can inhibit cell elongation without affecting cell division, inhibit the growth of stems and leaves without affecting the development of sexual organs, thereby achieving control of elongation, resist lodging and increase yield.

Gibberellic acid (GA3) can promote seed germination, plant growth, and early flowering and fruiting. It is widely used in a variety of food crops, and is even more widely used in vegetables.It has a significant promotion effect on the production and quality of crops and vegetables.
