| 摘 要： | 采用多因变量线性模型方差、变异系数、主成分分析及UPGMA聚类分析的数量统计方法，对来自内蒙古中东部地区的6个天然居群和2个栽培品种(品系)的花序10个数量性状进行了分析。结果表明，蒙古冰草在花序各部的表型性状上存在有居群内及居群间的差异，同时，天然居群的变异程度大于栽培品种，而且居群间的分化与生态环境因子有着密切的相关。 |
| 关 键 词： | 蒙古冰草 表型数量性状 统计分析 生态因子 相关性 |

| Abstract: | By means of the analytical techniques of GLM multivariate, coefficient of variation, principal component and UPGMA cluster, the phenotypic quantitative characters of inflorescence of Agropyron mongolicum Keng from 6 natural populations and 2 cultivars in the central and eastern areas of Inner Mongolia were analyzed. The results showed that there were some differences on the phenotypic characters within and among populations. Meanwhile, the degree of variation among 6 natural populations was greater than that between 2 cultivars, and the differentiation of populations had a close correlation with the ecological factors. |
