摘　　要：实验利用聚丙烯酰胺凝胶电泳(polyacrylamide gel electrophoresis,PAGE)技术对白榆(Ulmus pumila L)、垂榆(Ulmus pumilavar PeMdul)、欧洲大叶榆(Ulmus laevis Pall)、圆冠榆(Ulmus densa Litv)等4种常见榆树叶片的过氧化物酶进行分析测定,得出4种榆树过氧化物酶的谱带,并用排序分析法对其相似性做出分析,以此来鉴定出4种榆树的不同之处,并对4种榆树的形态特征进行了比较及鉴别和分类。In this paper,polyacrylamide gel electrophoresis was used for analyzing and determing peroxi- dases in leaf blades of Ulmus pumila, Ulmus pumilavar, Ulmus laevis and Ulmus densa, and getting peroxi- dase bands of four elms. Then, the sequence analysis method was used to identificate the differences of four kinds of elms. At the same time, comparison was made among the shape characteristics of four kinds of elms, and their discrimination and classification work was also done.
