摘要
多效唑(Multi—Effects Triazole,MET)是一种新型植物生长延缓物质,可控制水稻(Oryza sativa L.)秧苗徒长,提高IAA氧化酶活性,降低内源IAA水平,影响外源IAA对水稻秧苗的生长效应。
MET(Multi-Effects Triazole)is a new type of plant growth regulators.Soaking or spraying with 100~300 ppm MET was highly effective in controlHng plant height and promoting tillering of rice seedling(Indica and Japonica varieties).The experimental result has shown the antagonism between MET and exogeneous IAA on the growth of rice seedling.MET enhanced IAA-oxidase activity and reduced the content of endogeneous IAA in rice Seedling,thus affected the growth effect of exogenous IAA on rice seedling.
