摘　　要：50～200ppm MET处理,抑制小麦幼苗根系的垂直生长,促进根系发生,增加根冠比,增强根系活力,但不影响单株根系干重。进一步研究表明,MET降低过氧化物酶活性,促进同化物向根系运输,从而促进幼苗根系的形成。Effect of MET on the formation and vigor of roots of wheat seedlings were studied.The results showed that 50~200ppm MET inhibited vertical elongation of roots,increased root shoot ratio and enhanced the formation aad vigor of roots.But MET had no effect on the dry weight of roots.In the mean time the activity of peroxidase was decreased and the proportion ot assimilates in roots was increased bv MET treatment compared with the control.
