摘　　要：利用聚丙烯酰胺凝胶垂直平板电泳方法，测定禾本科植物狗尾草、看麦娘、鹅观草、鸭嘴草、白顶早熟禾、罗汉竹、小麦、狗牙根、倭竹等９种植物叶片的过氧化物酶（ＰＯＤ）和酯酶（ＥＳＴ）同工酶，结果表明被测植物的ＰＯＤ相似系数在２７以上，ＥＳＴ相似系数在２９以上．就其亲缘关系来看，倭竹与罗汉竹关系最近，其次鸭嘴草与白顶早熟禾的关系也较近．By means of polyacrylamide gel electrophoresis,two isozyme(POD & EST)in nine plants—? Dynodon dactylon (Linn.)Pers、 Ischaemum crassipes (Steud.)Thell.、 Setaria viridis (Linn.)Beauv.、 Roegneria Kamoji Ohwi 、 Shibataea chinensis Nakai 、 Phyllostachys . bambusodes var.aurea (Carr.ex Riv) Makino、 Poa acroleuca Steud 、 Alopecurus aequalis Sobol 、 Triticum aestivum Linn .——have been determined.The results show that each plant possesses its specific zymogram,and the species specialicity was rather obvious for the POD.Using Unweighted pair group arithmetic average,it indicates that their relationships are different.Their coeffectivent of POD is more than 27,and that of EST is more than 29.As far as the genetic relationship is concerned,Shibataea Makino and P.aurea(Sieb.)Makino are closest,Ischaemum crassipes (Steud.)Thell.and Poa acroleuca Steud.are closer.
