摘要
本文报道本所最近合成的某些硫代甲基膦酸酯类化合物的植物生长调节活性。合成的８个化合物中，７个化合物具有明显的植物生长调节活性：１０ｐｐｍ处理后均明显促进黄瓜子叶扩张，１００ｐｐｍ处理后明显抑制小麦胚芽鞘伸长。本文以Ｓ－乙基Ｏ－（２－氯－４－溴苯基）甲基膦酸酯（下文称２号化合物）为代表重点报道其对黄瓜子叶扩张，叶绿素含量的促进作用及对油菜下胚轴伸长的抑制作用。
This paper reports the activities of plant growth regulation of some thiomethylphosphonic acid derivatives at the first time. Most of the compounds have the significant activities of plant growth regulation. They show high promotion of the cucumber cotyledon expansion at 10ppm and show inhibit activities of the wheat coleoptile elongation at 100ppm. In this paper,we took compound No. 2 as a sample to describe the details of the cucumber cotyledon expansion,and chlorophyll content promotion,the inhibition of rape hypocotyl elongation etc.
