水分胁迫下小麦幼苗SOD活性的变化及脂质过氧化作用

The Change of Water Stress on SOD Active and Affect of LipidPeroxidation Induced in Wheat Seedling

在干旱条件下，小麦幼苗的根、茎、叶随干旱程度的增加，含水量、蛋白质总含量及ＳＯＤ活性均下降，而ＭＤＡ含量逐渐增高。原因是小麦幼苗在水分胁迫过程中其组织及细胞内存在着自由基的伤害作用。

On drought moisture content,protein total content and active of SOD all drops,but MDA content gradually rises for roots stems and leaves in wheat seedlings.Rease is that tissues and cells exist in juring affect on free base in wheat seedlings on drought
