摘　　要：为探讨起源地生态地理因素对野生二棱大麦营养性状的影响,对源自以色列不同地区9个野生二棱大麦群体的60个生态型材料的籽粒总氮、可溶性蛋白质、总淀粉含量等主要营养成分进行测定。经单因素方差分析(One-Way ANOVA)、相关性网络分析(correlation-based network analysis,CAN)和斯皮尔曼秩相关分析(Spearmanp’s Rho Correlation)等软件分析结果表明,以色列野生二棱大麦在群体、生态型水平和籽粒的主要营养成分均存在明显差异;总氮、可溶性蛋白质含量以及单粒重与起源地多个生态地理因素显著相关(P<0.05)。因此得出结论,野生二棱大麦是在长期适应起源地生态地理环境的过程中,在自然选择压力下形成了其特有的营养性状遗传多样性。To investigate the effect of eco-geographical factors of the origin on nutritional traits of wild bar-ley （Hordeum spontaneum） from different regions of Israel, the main nutritional components including total nitro-gen, soluble protein and total starch contents of nine wild barley populations in 60 eco-type material grains weremeasured by single factor variance analysis, correlation network analysis and Spearman Rho significant correla-tion analysis. The results showed that there were significant differences in the main nutrient components amongthe populations and ecological levels. The contents of total nitrogen, soluble protein and single grain weight weresignificantly correlated with multiple ecological geographical factors （P〈0.05）. These results indicated that thewild two-prism barley has gone through a long-term adaptation to the eco-geographical environment of the originunder the pressure of natural selection, forming its unique genetic diversity.
