Classification and use of common plant growth regulators
Synthetic chemical substances that regulate the growth and development of plants and natural plant hormones extracted from organisms, called plant growth regulators. It has been found that substances regulating plant growth and development are amine fresh ester (DA-6), chlorpyrifos, sodium nitrophenolate, auxin, gibberellic acid, ethylene, cytokinin, abscisic acid, brassinolide. , salicylic acid, jasmonic acid, paclobutrazol and polyamines, etc., and used as plant growth regulators in agricultural production are mainly the top 9 categories.
Common plant growth regulators are: amine fresh ester (DA-6), chlorpyrifos, sodium nitrophenolate, brassinomycin, gibberellin.
Corresponding effect

11. Inducing the production of female flowers Ethephon, naphthaleneacetic acid, indole acetic acid, chlormequat.
12. Inducing male flowers gibberellin
13, cut flowers preservation ammonia oxyethyl vinyl glycine, ammonia oxy acetic acid, silver nitrate, silver thiosulfate.
14. Formation of seedless fruits Gibberellin, 2,4-D, anti-fallin, naphthaleneacetic acid, 6-benzylaminopurine.
