| 摘 要： | 以辽宁省20世纪70年代以来有代表性的4个水稻主栽品种和新育成的水稻超高产品种为试材，比较分析齐穗后叶片中保护酶活性的变化，结果表明：随品种更替叶片超氧化物歧化酶(SOD)、过氧化物酶(POD)活性增加，膜脂过氧化产物MDA含量减少，这种趋势在倒3叶上尤为突出。表明超高产品种清除活性氧的能力增强，尤其是下位功能叶片，且在籽粒灌浆的中后期更为显。

| Abstract: | Four main rice varieties planted popularly since 1970s in Liaoning and a super high yield variety were uned to analysis the changes of the protective enzyme activities and lipid peroxidation after full heading stage. The result indicated that activities of superoxide dismutase(SOD)and peroxidase(POD)increased, while malondialdehyde(MDA)content declined as the new varieties being released. This tendency was more obvious for the 3rd leaf. The above results revealed that super high yield varieties has high ability of cleaning activized oxygen, and this ability was stronger in lower leaves or at late period of grain filling stage. |
