摘要
采用聚丙烯酰胺凝胶电泳的方法对蓟属的两个近缘种：大刺儿菜和小刺儿菜的过氧化物酶同工酶（ＰＯＸ）分别在不同的发育阶段和不同的生长条件下进行了比较研究。结果表明二者的酶谱存在着明显的差异，从而支持将它们作为两个独立的种对待。此外，本文还对ＰＯＸ酶谱的分类学意义进行了探讨。
By means of polyarcylamide electrophoresis,proxdase isoenzyme of 2 specics of Cirsium:C.setosum and C.segetum,which are morphologically very similar,have been comparatively studied at defferent development stages and on the wild and cultivated conditions; The results show that their POX electrophoretograms are different.Therefore,C. setosum and C. segetum are two in-dividual species is supported in this paper.In addition,the taxonomic significance of the elec-trophoretic banding patterns of peroxidase has been discussed.
