摘　　要：恒磁场处理水稻萌发种子，能提高幼苗内源抗氧化剂含量和膜保护酶活性。水稻幼苗经３℃冷害处理后，内源抗氧化剂含量和膜保护酶活性下降减少，电解质的相对渗漏率降低。Constant magenetic field will increase to different degrees the content of intrinsic antioxidation and the activity of protective enzyme of membrane in the budding leaf of crop seedlings. The seedlings, after treatment at 3° low temperature, will experience a reduction in its content of intrinsic antioxidation and a decrease in the activity of the enzyme, and a dropped rate of osmosis of electrolyte.
