摘　　要：水培和大田小区试验表明，１００μｇ／ＬＭＤ１处理，促进小麦幼苗根系发生，增加根冠比，控制植株生长，抑制植株基部１～３节节间长度，从而增强植株抗倒能力。生理和同位素示踪试验表明，ＭＤ１降低根系过氧化物酶活性，促进同化物向根系运输。此外。The results of water culture and field experiment showed that 100μg/L MD 1 enhanced the formation of roots of wheat seedlings, increased root: shoot ration, inhibited basal internode growth, thereby improved lodging resistance In the mean time, the activity of peroxidase was decreased and the proportion of assimilates in roots was increased by MD 1 treatment compared with the control It was also found that MD 1 improved the ear traits of wheat to some extent
