6-Benzylaminopurine(6-BA) has a variety of physiological effects:
1. Promote cell division and have cytokinin activity;
2. Promote differentiation of non-differentiation tissues;
3. Promote cell enlargement and growth;
4. Promote seed germination;
5. Induce the growth of dormant buds;
6. Inhibit or promote the elongation of stems and leaves;
7. Inhibit or promote root growth;

Mepiquat chloride is a new plant growth regulator that can be use for a variety of crops and exerts multiple effects. It can promote plant development, advance flowering, prevent shedding, increase yield, enhance chlorophyll synthesis, and inhibit the elongation of main stems and fruit branches.

Naphthalene acetic acid (NAA) is a synthetic plant growth regulator belonging to the naphthalene class of compounds. It is a colorless crystalline solid, soluble in water and organic solvents. Naphthalene acetic acid (NAA) is widely used in the field of plant growth regulation, especially playing an important role in the growth and development of fruit trees, vegetables and flowers.

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.
