美国密执安大学园艺系 S·K·Ries 教授,1975年把切碎的苜蓿干草施用在蕃茄根部,发现能提高蕃茄产量。后来 Ries 教授从苜蓿干草中提取出一种晶体,经质谱分析证明是三十烷醇(TRlA),把这种晶体经有机溶剂溶解再兑水稀释后,在实验室中试验有促进植物生长的生理活性。于是 S·K·Ries 教授在1977年发表论文,称三十烷醇是一种植物生长调解剂。 Professor S. R. Ries, Department of Horticulture, University of Michigan, USA, applied shredded alfalfa hay to the roots of tomatoes in 1975 and found that it can increase the yield of tomatoes. Later, Professor Ries extracted alfalfa hay from a crystal, identified by mass spectrometry triacontanol (TRlA), the crystals dissolved in organic solvents and diluted with water, in the laboratory test to promote plant growth Physiological activity. So Professor S.K.Ries published a paper in 1977, said triacontanol is a plant growth regulator.
