不同油豆角品种过氧化物酶活性及其同工酶酶谱分析

Study on Peroxidase Activity and Its Isozyme Patterns Among Species of Snap Beans

应用过氧化物酶同工酶技术,通过相似系数比较和聚类分析,比较7个油豆角品种不同器官过氧化物酶(POD)的活性,并对其亲缘关系进行探讨。结果表明:不同品种POD活性不同,同一品种不同器官的POD活性也不同,根部的POD活性高于叶的,而叶片的高于茎的;不同器官POD酶谱不同,同一器官不同品种的酶带数也不尽相同;‘油豆子’、‘俏春大荚油豆王’和‘齐研五号架油豆’亲缘关系比较近;‘俏春3号地油’与‘油豆子’的亲缘关系最远。

In this paper,the POD activity in different cultivars was different from the same species.the POD activity in roots was higher than that in leaves and in leaves higher than stems.POD isozyme patterns in different organs were different and that in same organ of different species were different.Analysis showed that ＂Youdouzi＂ was very near to ＂Qiaochundajiayoudouwang＂ and ＂Qiyanwuhao＂ in genetic relationship.The relationship between ＂Youdouzi＂ and ＂Qiaochun3haodiyoudou＂was the farthest.
