| 摘 要： | 目的]探究低浓度NaCl对高粱生长的效应。方法]以非盐生C4植物高粱为材料,以Hoagland溶液为基础培养液,用NaCl3种浓度（5、10、20mmol/L）处理高粱苗,采用沙培法研究低浓度NaCl对高粱生长的影响。结果]从长势上看,NaCl低浓度（5mmol/L）处理的植株长势要优于对照,NaCl中浓度（10mmol/L）处理的植株长势与对照相近或比对照略差,NaCl高浓度（20mmol/L）处理的植株长势明显比对照差。3种浓度处理中以低浓度NaCl促进高粱生长的效果最佳,主要表现在：与对照相比,高粱的根系活力增加16.2%（P〈0.05）;植株叶绿素a、叶绿素b和叶绿素总量分别增加9.4%（P〈0.01）、7.9%（P〈0.05）和9.0%（P〈0.05）;高粱叶中可溶性蛋白含量增加22.9%（P〈0.05）;高粱的鲜重和干重分别增加23.2%（P〈0.01）和17.5%（P〈0.05）。结论]低浓度NaCl可以促进高粱生长。

| Abstract: | Objective] The study aimed to explore the effect of NaCl at low concn.on the growth of sorghum.Method] With non-halophytes C4 plant sorghum as the material and Hoagland solution as the basic cultural liquid,the seedlings of sorghum were treated with NaCl at 3 kinds of concn.(5,10,20 mmol/L)and the effects of NaCl at low concn.on the growth of sorghum were studied by using sand culture method.Result] From the view of sorghum growth vigor,the sorghum plant treated with NaCl at low concn.(5 mmol/L)was bette... |
