| 摘 要： | 用不同浓度混合盐碱(NaCl/Na2CO3)对苗期紫花苜蓿进行胁迫处理,测定其对抗氧化酶系统和丙二醛含量的影响。结果表明,随着混合盐碱处理浓度的增大,经处理的苗期紫花苜蓿叶片的超氧化物歧化酶(SOD)、过氧化物酶(POD)、过氧化氢酶(CAT)活性及丙二醛(MDA)的含量呈增加趋势,并且均高于对照。

| Abstract: | The Medicago sativa cv.Gongnong No.1 were stressed by different concentrations salt-alkali(NaCl/Na2CO3) at seedling stage.Activities of SOD,POD,CAT and MDA of M.sativa leaf were determined at seedling stage.Activities of SOD,POD,CAT and MDA were increased with increasing salt concentrations,and higher than CK. |
