| 摘 要： | 根据实地调查结果, 对来自10个种群的蜡梅 (Chimonanthus praecox (L. ) Link ] 花性状进行了变异分析, 结果发现: 在花的质量性状和数量性状的变异上, 种群内和种群间均存在很大的差别。对花性状和地理生态因子进行相关分析发现, 经度、纬度、年降水量和年均温等与各性状值的大小相关性都不显著, 但花被片数和中被片数却和海拔高度呈显著的负相关。

| Abstract: | The flower variation of 10 winter-sweet populations was analyzed on the basis of the on-the-spot investigations. The results showed that there was a significant difference on the winter-sweet qualitative and quantitive characters among populations and among individualswithin populations. The correlation analysis between the flower character of winter-sweet and geography ecological factors showed that the correlation between them is not significant exceptaltitude, but the perianth number and the middle-perianth number present a distinct negative correlation with altitude. |
