| 摘 要： | 分别用不同浓度的NaCl溶液处理两个品种的玉米幼苗,两周后测定丙二醛（MDA）、脯氨酸（Pro）含量以及过氧化物酶（POD）活性等生理指标。结果表明：在NaCl处理下,农大108的MDA含量低于沈单10号,Pro含量、POD活性高于沈单10号。说明农大108的耐盐性较强。

| Abstract: | Seedlings of two different varieties of Zea mays L.were treated with different levels of NaCl solutions for two weeks.Then the content of malondialdehyde(MDA),proline(Pro)and the activity of peroxidase(POD) were measured.The results showed that the content of MDA in Nongda 108 was lower than that in Shendan No.10.However,the content of Pro and the activity of POD in Nongda 108 were higher than those in Shendan No.10.It could be concluded that Nongda 108 was more tolerant to salt stress than Shendan No.10. |
