大白菜幼苗过氧化物同工酶的研究

Study on Peroxidase Isoenzyme in Seedling of Chinese Cabbage

用聚丙烯酰胺凝胶电泳对萌发14天内的大白菜幼苗的过氧化物同工酶进行分析．结果表明，萌发4～8天的幼苗过氧化物同工酶表达比较明显，不同品种的酶带在表达时间上有一定的差异，过氧化物同工酶主要由根部进行表达．

The article analysed the peroxidase isoenzyme in seedling of Chinese Cabbage which had been cultured for 14days by polyacrylamide gel electrophoresis （PAGE）. The result indicated peroxidase isoenzyme in seedling cultured for 4 ～ 8days began to express obviously. The express time of enzyme strips of various varieties were different and the enzyme strips expressing obviously existed in roots.
