摘要：

用聚丙烯酰胺凝胶板电泳分析了杨属全部5个组26种又3变种，及其他欧

美杨无性系、人工种间杂种的阳极同工过氧化物酶。实验表明，叶柄和茎的酶谱

相当稳定。整个酶谱分5组。c组酶为整个杨属所共有。b组只限白杨组各种，

而且只有白杨组才缺乏a组各酶带。d组酶带最多、最复杂，充分显示出种的专

一性。根据酶谱可以鉴定种、变种，甚至某些无性系。看来，杨属植物在形态进

化的同时，发生了过氧化物酶的分歧。

Abstract:

Isoperoxidases of 26 species and 2 varieties, belonging to 5 sections of Populus,

were analysed by means of polyacrylamide gel slab electrophoresis. Experimental

evidences indicate that the zymograms of petioles are stable. Whole anodal isozymes

may be divided into 5 groups; a.b.c.d.e. Every species of Populus shared the c group

isozymes. The b group is limited within the section Leuce, and only in this section, the

a group enzymes are absent. The d group is very complicated, and fully expressed the

species-specificity. Base on their specific zymograms, it is easy to distinguish one

species from the others, sometimes, we can characterize the varieties, even some clones.

It seems that, in the course of morphological evolution of Populus, the divergence of

their isoperoxidases also occurred.
