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.
