三十烷醇作为新型植物生长调节剂,于 1977年由美国密执安州立大学发现报道后, 引起世界普遍地关注。中国科学院上海植物生理研究所对多种作物进行试验,有提高植株体内碳氮代谢水平的效应,并对作物的营养器官与生殖器官的生长发育具有促进作用。在杂交水稻三系花时观察中,发现三十烷醇对不育系花时性状有调节作用。但对恢复系花时无明显影响。由于杂交水稻父母本开花习性的差异,开花时间的不一致,往往花 Triacontanol, as a new plant growth regulator, was discovered in the United States by Michigan State University in 1977 and has aroused widespread concern in the world. The Chinese Academy of Sciences Shanghai Institute of Plant Physiology on a variety of crops tested to improve plant carbon and nitrogen metabolism in the level of the effect and the vegetative organs and reproductive organs of the crop growth and development have a catalytic role. In the observation of three-line hybrid rice during flowering, triacontanol was found to have a regulatory effect on the flowering-time trait of the sterile line. However, there is no obvious effect on the recovery of flowers. Due to differences in the flowering parents of hybrid rice parents, flowering time is inconsistent, often spent
