植物生长调节剂在1896年发现。之后又相继发现多种药物能影响植物正常生化过程,某一用量能刺激植物生长,另一用量则抑制生长。近十余年来,农业化学化的一个重要方面是将生长调节剂用于调节植物生长、脱叶、催熟,以至增加产量。在结构或功能上与天然生长调节剂相似的合成调节剂,已有5000余种,实用的仅约1％。植物生长调节剂的理论研究,着重于其在植物体内的生物合成与转化调节作用机制,阐明其调节植物生长发育的机理。在农业生产实践中,应用于培育新品种及改善栽培生理状况,使大豆的产量及含油 Plant growth regulators were discovered in 1896. Later on, one after another found that many kinds of drugs can affect the normal biochemical process of plants. One dose can stimulate plant growth while the other dose inhibits growth. For more than a decade, an important aspect of agrochemicalization has been the use of growth regulators to regulate plant growth, defoliation, ripening and even increasing yields. There are more than 5,000 species of synthetic regulators similar in structure or function to natural growth regulators, with only about 1% being practical. Plant growth regulator theoretical research, focusing on its biosynthesis in plants and transformation regulation mechanism, to clarify its mechanism of regulating plant growth and development. In the practice of agricultural production, applied to cultivate new varieties and improve the physiological conditions of cultivation, so that soybean production and oil
