为揭示秦巴山区野百合天然居群的表型变异，对该地区17个野百合天然居群花、叶的8个质量性状和21个数量性状进行了观测。结果表明：野百合在秦巴山区适应性强、分布范围广，而且大多生长在海拔705~1913 m 的高山；表型性状变异丰富；上部叶片长与纬度存在显著正相关，柱头宽、上部叶片长与海拔高度存在显著正相关，下部叶间距与年降水量存在显著正相关，花梗长和上部叶片长与年均温度存在显著负相关；17个野百合天然居群被系统聚类为巴山和秦岭2大组。该研究结果为进一步开展野百合遗传育种、保护生物学的研究奠定了基础。

In order to reveal the phenotypic variation of Lilium brownii in natural populations native to Qinba moun-tainous area,and to discuss the relationship between phenotypic variation of natural populations,a systematic investi-gation was carried out among 17 natural populations in this area,containing 21 quantitative traits and 8 qualitative traits of both the flowers and the leaves.The results were as follows:with a strong adaptability,L .brownii had a wide distribution range of this area,most of them lived in mountains at an altitude height varying from 705 m to 1 913 m;Rich variation took place in the phenotypic traits.The length of the top leaves had a notably positive correlation with latitude,the width of the stigmas and the length of the top leaves had a notably positive correlation with altitude, the bottom leaf spacing had a notably positive correlation with the annual precipitation,while the length of pedicel and the length of the top leaves had a significantly negative correlation with the mean annual temperature;L .brownii n-ative to Qinba mountainous area could be divided into 2 groups:Group Qinling and Group Bashan,according to the re-sults of UPGMA cluster analysis.These findings may offer basic data for further studies on genetic breeding and con-servation biology of L .brownii .
