Abstract: The morphological characteristics of seven cultivars of Codiaeum variegatum were compared in this study.Moreover,the peroxidase isozyme of seven cultivars was analyzed by means of polyacrylamide electrophoresis.The results showed that the peroxidase isozyme pattern of seven cultivars was inequable,which included a total of 14 bands.Among them,the Num-2 band was the most of 11,and the Num-5 band was the lowest of 6.The isozyme pattern was divided into three parts (A=0-0.18,B=0.18-0.35,C=0.35-0.5).The genetic relationship of seven cultivars was studied by clustering analysis.

Key words: Codiaeum variegatum, peroxidase isozyme, polyacrylamide electrophoresis, clustering analysis

摘要： 本试验对7个品种变叶木的形态特征进行比较,并利用聚丙烯酰胺凝胶电泳,对各品种过氧化物酶同工酶进行分析。结果表明,各品种的过氧化物酶同工酶谱不一;7个品种变叶木共有14条谱带,2号谱带最多为11条,5号谱带最少为6条;其谱带分为3个区(A=0~0.18,B=0.18~0.35,C=0.35~0.5);并对7个品种的亲缘关系进行聚类分析。
