植物生长调节剂的作用：疏花疏果、保花保果、植物保健、植物伤口愈合、解害扶苗、增强抗性、促长状苗、扦插生根、促块茎发育、促发新根、贮藏保鲜、增加分蘖、增甜着色、防治裂果、控制徙长、促幼果发育
世界上已经人工合成了几百种植物生长调节剂，有近百余种在农业生产中得到了广泛的应用，比如多效唑、烯效唑、矮壮素、乙烯利、甲哌鎓、氯吡脲、苄氨基嘌呤、抑芽丹、胺鲜酯、芸苔素内酯、三十烷醇、赤霉酸、丁酰肼、萘乙酸、吲哚乙酸、激动素、复硝酚钠、对氯苯氧乙酸钠等。

The function of plant growth regulator: flower and fruit thinning, flower and fruit protection, plant health care, plant wound healing, anti-harm and seedling support, enhance resistance, promote long seedlings, cutting rooting, promote tuber development, promote new roots, storage and preservation, increase tillering, sweetening and coloration, prevention and control of cracking fruit, control of migration, promote young fruit development
Hundreds of plant growth regulators have been synthesized in the world, and more than 100 of them have been widely used in agricultural production. For example, paclobutrazol, eniobutrazol, dactyloxazole, ethephon, methylpiperium, chlorfenuron, benzaminopurine, yastydan, aminofresh ester, brassinolide, thirty anol, earlic acid, butanoyl hydrazine, naphthylacetic acid, indoleacetic acid, agonin, sodium complex nitrophenol, sodium p-chlorophenoxy acetate and so on.
