POD同工酶在酸枣、枣分类中的应用

运用聚丙烯酰胺凝胶电泳（ＰＡＧＥ）技术，对来自不同产地的８３个酸枣类型（品种），及３６个枣品种的叶片过氧化物酶（ＰＯＤ）同工酶扫描数据，进行了主因子分析和聚类分析研究。结果表明，运用距离系统的类平均法（ＵＰＧＭＡ）可将全部试材划分为六大类群和３个特殊型，且聚类结果与地理位置直接相关。此外，依同工酶带的有无，可将全部供试枣品种叶片ＰＯＤ同工酶合并为５种谱型，全部酸枣类型（品种）合并为２２种谱型。大马

A STUDY ON THE CLASSIFICATION OF JUJUBE AND WILD JUJUBE BY PEROXIDASE ISOZYME

This test was carried out with polyacrylamide gel electrophoresis.Peroxidase isozyme data of eighty- three species of wild jujube and thirty- six varieties of jujube,which came from different places, were analysed with principal factor analysis and cluster analysis methods.The results showed that all the materials used in this testcould be classified into six clusters and three special types by unweighted pair- group mean average( UPGMA) method.And the classification results had direct relationship with geography.Meanwhile,five zymogram types of leaf peroxidase of cultivars were obtained according to the appearance of isozyme band,while all the wild forms had twenty- two.One of the jujube varieties named Da Maya had special zymogram type and was conjectured to be the transitional cultivar between cultivars and wild forms in this test.
