| 摘 要： | 根据小叶锦鸡儿(Caragana microphylla Lam.)资源分布状况，对内蒙古东部地区的13个小叶锦鸡儿天然居群进行表型变异研究。结果表明：小叶锦鸡儿表型性状在居群间均表现为极显著差异（p<0.001）；主成分分析显示种子宽、种子长、荚果长是小叶锦鸡儿表型变异的最主要影响因子；回归分析和偏相关分析显示地理生态因子对小叶锦鸡儿的表型变异有较强的影响；通过聚类分析将13个小叶锦鸡儿居群分为3类。

| Abstract: | Based on the natural distribution of Caragana microphylla Lam.in China,thirteen populations of C.microphylla Lam.collected in the East part of Inner Mongolia were evaluated by their morphological variation.Main results obtained are as follows:Results from the single factor variance analysis showed that there was a significant variation in the 13 populations studied.The principal analysis indicate that seed length,seed width and pod length were the main sources of morphological variation.Results from the reg... |
