- 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 twoweeks.Then the content of malondialdehyde (MDA), proline(Pro)and the activity of peroxidase(POD)were measured.Theresults showed that the content of MDA in Nongda 108 was lower than that in Shendan No.10.However, the content of Proand the activity of POD in Nongda 108were higher than those in Shendan No.10.It could be concluded that Nongda 108wasmore tolerant to salt stress than Shendan No.10.
