BR—120属芸苔内酯类物质简称BR,是一种对植物生长有很高活性的新型植物生长调节剂。80年代中期我国(中科院植生所)也对此进行研究,90年代前期云南大学生物系研制出一条原料易得,操作简便,成本较低,具有工业化生产价值的合成路线并投入批量生产。 经过近10年研究和应用,现已肯定其四大生理功能:促进细胞分裂和伸长,有利于花粉受精,提高座 BR-120 belongs to brassinolide abbreviation BR, which is a new plant growth regulator with high activity on plant growth. In the mid-1980s, China (Institute of Plant Physiology, Chinese Academy of Sciences) also studied this issue. In the early 90s, the Department of Biology, Yunnan University developed a synthetic route with easy-to-obtain raw materials, simple operation, low cost and industrialized production value and put it into mass production. After nearly 10 years of research and application, has now identified its four major physiological functions: to promote cell division and elongation, is conducive to pollen fertilization, improve seat
