摘  要:
本文采用聚丙烯酰胺凝胶电泳法,对鹅观草属和披碱草属共12个四倍体种的幼根、幼芽进行了酯酶同工酶分析。用数学方法对所分析的酶谱进行了聚类分析。结果表明R.abolinii var.divaricus和R.dolichathera, R. ciliaris和R.hondai, R.gmelinii和R.strict, R.angustiglumis和R.komarovii间在幼根和幼芽上的酶谱均表现很相似,分别被聚在一起,而E.angustiglumus和R.komarovii聚在一起与染色体组分析相矛盾。说明同工酶虽然可以鉴别种内和种间差异,但不能反映属种间亲缘的关系。

摘  要:
The esterase isoenzyme of 12 species of Roegneria C. koch and Elymus have been studied by means of polyarcylamide electrophoresis. By examining the characteristic isoenzymatic patterns and unweighted pair-group method using mathematic average cluster analysis, R. ciliaris and R. hondaii, E. angustiglumus and R. komarovii, R. stricta and R. gmelinii, R. dolichathera and R. abolinii var. divaricus are clustered together. V/hile E. angustiglumus and R. komarovii are clustered together contradict with the genome analysis. The results indicated that isoenzyme analysis can identify the difference among species and accessions of same species, but cannot indicate the phylogenetic relationships among genera.
