摘　　要：合成了三种新型含硅植物生长调节剂 (Ⅴ～Ⅶ ) ,它们的结构经元素分析、IR和′HNMR表征。生物活性试验表明 ,药液质量浓度为 2 5mg/L时 ,三种目标化合物对水稻根生长比对照化合物 ( 1-茶乙酸苯基二甲硅基甲酯 ,Ⅷ )分别提高 19%、14%和 15%。Three kinds of new plant growth regulators containing silicon—ethyldimethylsilylmeth\| yl 5-isobutyryl-1-naphthylacetate,phenyldime thylsilylmethyl 5-isobutyryl-1-naphthylacetate and benzyldimethylsilylmethyl 5-isobutyril-1-naph thylacetate have been synthesized.Their structures were characterized by elementary analysis,IR and ′HNMR.The results of biological activity tests showed that three target compounds increased the growth rate of the rice root by 19%,14% and 15% than the phenyldimethylsilylmethyl 1-naphthylacetate at concentration of 25 mg/L,respectively.
