摘要
研究了烯效唑浸种对玉米苗期形态特征的影响。结果表明 :烯效唑对叶片和叶鞘的伸长生长有明显的抑制作用 ,且抑制效应随浓度的增大而增强 ;烯效唑处理的植株粗壮 ,叶片厚度、叶宽和茎基宽增加 ,根数增多 ,根长显著高于对照 ,根干重增加 ,根冠比和苗粗壮度提高 ,表现出显著的壮苗长相 ,浓度间以 40mg
The effects of soaked seeds with different concentrations on t he growt h of maize seedlings were studied The results showed as follows The elong ation of leaf blades and leaf sheaths of the treated plants was inhibited at 3～ 7 leaf stage, and the higher of the concentration, the stronger of the effect A t the same time, as compared to the control, the plant in uniconazole-treatment s howed an appearance of high quality plant with increased specific leaf weight, l eaf width and stem thickness as well as root number and root length, the root dr y weight, and 40 mg/kg was the best
