摘要
采用不连续垂直板聚丙烯酰胺凝胶电泳法,对连续自交四代和开放授粉的4个甘蓝型油菜品系叶片过氧化物酶(POD)和酯酶(EST)同工酶进行酶谱分析。结果表明,4个品系开放授粉POD同工酶活性强于各自交世代;EST同工酶酶带除品系03武240-1开放授粉的酶活性较其自交世代弱外,其余3个均强于自交世代,说明连续自交会使甘蓝型油菜后代的生活力减弱,但品系间有差异。
Using vertical plate discontinuous polyacrylamide gel electrophoresis,analysis the leaf peroxidase（POD） and esterase（EST）isozyme for four successive selfing generations and open pollination four Brassica napus L.. The result shows that the POD isozyme of the open pollinated are stronger than self- generations;the EST isozyme of the open pollinated are stronger than self- generations in addition to 03 Wu 240- 1,Successive selfing led to reduction of viability of Brassica napus L.,but there are differences between strains.
