摘　　要：以连续自交四代的甘蓝型油菜品系03武291-2X和03武240-1为材料,以开放授粉为对照测定了S1,S2,S3,S4不同生育期叶片的SOD,CAT,APX活性变化。结果表明:在整个花期对照叶片的SOD,CAT,APX活性均显著高于自交后代,说明自交对常异花授粉植物甘蓝型油菜有一定伤害,避免过分严格的自交对于保持常规品种的优良特性是有益的。The SOD, CAT and APX differences between self-pollinaton materials and open-pollination materials were tested by using Brassica napus materials 03Wu291-2X and 03Wu240-1. The results showed that：the SOD, CAT, APX activity of the normal leaves were significantly higher than that of the self-generation ; The self-pollination was harm to Brassica napus ; It is useful to avoid strictly selfing for maintaining the excellent characteristics of conventional varieties.
