| 摘 要： | 以文冠果为研究对象,调查了14个分布区文冠果的15个表型性状,利用变异系数和巢式方差分析研究了分布区间和分布区内的变异情况;应用相关分析揭示了表型性状间及其与地理因子间的关系;运用聚类分析进行了分布区分类.结果表明,文冠果分布区内的变异大于分布区间的变异,分布区间的分化相对较小;出种数随经度的增大而减少,果宽随纬度的增大而增大,但随年平均气温的增大而减小,而其它13个性状随地理位置的改变没有特别明显的变化;表型性状的欧式距离与地理距离相关不显著. |
| 关 键 词： | 文冠果 表型多样性 分布区分化 |

| Abstract: | 15 phenotypic traits were investigated for 14 populations of Xanthoceras sorbifolia Bunge. Phenotypic variation, which were among populations and within populations, were studied by using nested variance analysis and variation coefficient. The correlation analysis and cluster analysis showed the relation among traits and geographical factors. The variation within populations was much greater than that among populations. The seed number in fruit was decreased with the longitude increase. The fruit width was improved with latitude increasing and the annual mean temperature decreasing. There was no significant relationship between geographic distances and euclidean distance. |
| Keywords: | Xanthoceras sorbifolia phenotypic diversity distribution differentiation |
