摘要
本文通过对不同来源大赖草及其可能供体物种的EST、GOT、SOD同工酶及HMW－GS的分析，发现不同来源大赖草的同工酶及蛋白图谱呈一定差异，但其中为不同来源大赖草所共有的一些谱带，同时也存在于具N染色体组物种的分析图谱中，而在具J染色体组的物种中却没有特异性分布，推断大赖草中含有N染色体组，但可能不含J染色体组。
The zymogram phenotypes of Esterase(EST), Glutamate oxalocate transminase(GOT),Superoxide dismutase(SOD) and the banding patterns of high molecular weight glutenin subunits(HMW-GS) were determined for different Leymus racemosus accessions and their putative do nor species. It was found that although the zymogram phenotypes and the HMW-GS banding patterns appeared polymorphism, common bands for different Lr accessions wcre found in the species with N genome, but not in those with J genome, suggesting that the Psathyrostachys species with N genome must be phylogenetically closer to Lr, while the Thinopyrum species with J genome are farther to it.
