摘要/Abstract

摘要： 玉米开花期土壤干旱可使叶细胞中的超氧物歧化酶（SOD）活性降低，丙二醛（MDA）含量增加；酸性磷酸酯酶活性增强，可溶性磷含量增加。随干旱加强，MDA含量增加与亚麻酸含量降低呈极显著负相关，亚油酸含量增加与亚麻酸含量降低呈极显著负相关，酸性磷酸酯酶活性与膜脂脂肪酸不饱和度的变化呈相反的趋势。电镜观察发现，干旱

Abstract: Soil drought during flowering period of maize resulted in decrease of SOD (superoxide dismutase) activities and increase of MDA (malonaldehyde) contents in leaf cells, acid phosphatase activities and soluble phosphotus contents elevated. There was significant negative correlationship between MDA and
