摘要
分别用浓度为0、100、200 mmol.L-1的NaCl溶液以及100 mmol.L-1 NaCl+5 mmol.L-1 CaCl2溶液、200 mmol.L-1 NaCl+5 mmol.L-1 CaCl2溶液处理小麦幼苗,然后于第1、第4、第7天测定幼苗脯氨酸(Pro)、丙二醛(MDA)含量和过氧化物酶(POD)活性,通过相关生理指标变化,探讨外源钙对小麦幼苗耐盐性的影响。结果表明,经CaCl2处理的小麦幼苗,其脯氨酸含量增加,过氧化物酶活性增强,丙二醛含量降低。可知外源CaCl2提高了小麦幼苗的耐盐性。
Seedlings of Triticum aestivum L. were treated with three different NaCI concentrations （0,100,200 mmol·L-1） and sprayed with 1.00mmol·L-1 NaCI＋5 mmol·L-1CaC12,200mmol·L-1 NaCI＋5 mmol·L-1 CaC12 solution,then the content of proline, MDA and the activity of POD were determined. The main purpose of this experiment was to examine the changes in Triticum aestivum L and to explore the influence of Calcium on salt tolerance of Triticum aestivum L. seedlings. The results showed that the content of proline increased and the POD activity enhanced, but the content of MDA decreased. It could be concluded that exogenous calcium could increase salt tolerance of Triticum aestivum L. seedlings.
