摘要
运用电泳技术，测定了重庆北碚特产的缙云卫矛（Ｅｕｏｎｙｍｕｓｃｈｌｏｒａｎｔｈｏｉｄｅｓ）３个居群３６个个体功能叶片的过氧化物酶（Ｐｅｒｏｘｉｄａｓｅ，ＰＯＤ），酸性磷酸酯酶（Ａｃｉｄｐｈｏｓｐｈｏｅｓｔｅｒａｓｅ，ＡＣＰ）的同工酶谱带，并进行编码；然后采用ＲｏｇｅｒｓＴａｎｉｍｏｔｏ结合系数的组平均法（ＵＰＧＭＡ）对各酶谱带进行聚类分析；同时结合遗传杂合度（Ｈｅ）、遗传相似性系数（Ｉ）、遗传距离（Ｄ）进行分析．结果表明，来自同一居群的个体，不但同工酶谱相似性高、遗传杂合度小，而且遗传相似性系数大、遗传距离小，显示出居群内个体遗传分化小；显示出居群之间的个体却刚好相反．这是由于其特殊的生殖方式和环境隔离所致．
According to the investigation and study,there are 40 species and 5 varieties of berberis genus in Sichuan,including 7 species and 2 varieties which are found recently and 2 species which just produced in Sichuan.Seven species and 1 variety belong to superior resource plants which are discovered for the first time.The level and vertical distribution laws have been analysed and summarized here.The level distribution can be divided into 5 natural vegetation areas. The range of vertical distribution is elevation 500～4000m. The comlinative estimation to these resources and introduction on the ways of their exploitation and utilization is obtain.
