摘　　要：为了探讨槭属树种的亲缘关系及演化趋势,对采集的68份槭树种质材料(包括27个槭属树种以及7个变种)的7个翅果性状用SAS8.0统计分析软件进行主成分分析,结果表明:前3个主成分的累计贡献率达83.9%,可分别代表翅果大小、翅果角度和产量的综合因子。另外,根据翅果的7个性状进行聚类分析,进一步明确槭属树种的亲缘关系,为槭树种质资源的研究提供了重要依据。Seeking for the relativeness and evolvement trend of maple, seven samaras characteristics of 68 maple germplasms （including twenty -seven species, two varieties and two cultivars） were made the principal component analysis using SAS8.0 statistical software. The results showed the cumulative was up to 83.9% of the first three principal components which represented integrated factor of size, angle, yield respectively. In addition, according to clustering analysis of seven samaras characteristics, relativeness of maple was discussed furtherly, which provided important information for the research of maple germplasm resources.
