云南大学研制生产的云大—120新型高效植物生长调节剂(原BR—120芸苔素内酯),是国际上最新型的高效植物生长调节物质,属于农业上的高科技成果。 BR作为一种植物内源性激素,已知其四大生理功能是:①促进细胞的分裂和伸长;②提高叶绿素含量,增强光合作用;③有利花粉授精、提高坐果率和结实率;④改善植物生理代谢作用,增强抗逆性。因此,BR对多种植物具有良好的增产和改善品质的功能。其最大特点是生物活性极高,有碳、氢、氧三种元素,经毒理实验及大量田
Yunnan University research and development of cloud-120 new efficient plant growth regulator (formerly BR-120 brassinolide), is the latest in the world of efficient plant growth regulator, is a high-tech agricultural achievements. As a plant endogenous hormones, BR is known to have four major physiological functions: ① promoting cell division and elongation; ② increasing chlorophyll content and enhancing photosynthesis; ③ favoring pollen insemination, improving fruit set rate and seed setting rate; ④ improving plant Physiological metabolism, enhance resistance. Therefore, BR has a good yield and quality improvement function for many kinds of plants. Its most prominent feature is a highly bio-active, carbon, hydrogen, oxygen three kinds of elements, toxicological experiments and a large number of fields
