摘  要：
山杏是内蒙古地区的生态经济型树种,对其进行多样性研究可为新品种的选育、遗传改良提供理论依据。本文以内蒙古地区10个种源山杏为研究对象,分别对杏核与杏仁共10个表型性状进行多元分析。结果表明:山杏各表型性状在种源间和种源内均存在极显著差异;10个种源各性状平均变异系数为16%,变异幅度为9%~28%;种源间平均表型分化系数达61.56%,大于种源内分化系数,变异主要来源于种源间;山杏核仁表型性状的Simpson多样性指数为0.839~0.862,Shannon多样性指数为2.855~3.016,杏核多样性指数平均值均大于杏仁;表型性状与经度、温度、降水量以及海拔呈显著相关,表现出一定的地带性规律;对表型性状进行系统聚类分析,将10个种源划分为3大类群,与地理生态因子表现出一致性。

摘  要：
Apricot is an ecological and economic tree species in Inner Mongolia,and the study of its diversity can provide theoretical foundation for the selection and genetic improvement of new varieties of the apricot. Taking apricot from 10 provenances as the object,a multivariate analysis was conducted on the phenotypic characters of apricot stone and almond. The results showed that extremely significant difference appeared both among and within provenances. The average variation coefficient of each characteristic of 10 provenances reached 16%,with a range of 9%- 28%. The average coefficient of phenotypic differentiation among provenances achieved 61. 56%,which was higher than the coefficient of phenotypic differentiation within provenances,indicating that the differentiation derived mainly from inter-provenances. The Simpson diversity index and Shannon diversity index of the apricot's phenotypic character of stone and almond ranged from 0. 839 to 0. 862 and 2. 855 to 3. 016 respectively,and the average value of diversity index from the apricot stone was all higher than that of the almond. There existed a clear correlation between phenotypic character and longitude,temperature,precipitation and altitude,which showed obvious zonal patterns.Meanwhile,by systematical cluster analysis on the phenotypic characteristics of apricot,the 10 provenances were grouped into 3 categories,being consistent with the geogra-phical factors.
