    摘要:

    在小果油茶全分布区内,选择有代表性的18个居群为研究对象,对种实、花及的23个表型性状进行统计分析,结果表明:小果油茶的居群内及居群间均存在广泛的表型变异,其随环境的变化表现出较强的表型可塑性。小果油茶叶、花及种实形状大小存在着显示的相关关系,可以从中选出表型性状中的重要及关键表型性状作为测定的主要依据。小果油茶表型性状与生态地理因子有一定的相关关系,且不同性状受地理生态因子影响也不同,其中花性状最大,而种实和叶相对较小。利用居群间的欧氏距离进行UPGMA聚类,结果显示,18个小果油茶居群可分为4个类群,且按较明显的地理区域特征进行聚类。从系统聚类图和主成分排序图比较来看,绝大多数居群在两种聚类方式中保持着一致结果,说明两者均能较好地区分小果油茶不同居群的亲缘关系,可为小果油茶的种质资源收集和良种选育打下了良好的基础。

    Abstract:

    In this study, 18 geographic population were selected in all the flora of Camellia meiocarpa Hu 's. Twenty-three phenotypic traits from fruits, seeds, flowers and leaves were analyzed statistically. The results showed that there were a wide phenotype variation within or between populations, indicating a stronger phenotypic plasticity with the change of environmen.There were significant correlations among some phenotypic traits such as leaves, flowers and fruits. Thus, we selected some important and key traits as primarily measured parameters. Certain correlations were also found between phenotypic traits and ecogeographical factors. The phenotypic traits of flowers were the most sensitive to ecogeographical environment, but the leaves, seeds and fruits were relatively insensitive. Eighteen populations of C.meiocarpa were divided into 4 groups with obvious geographic feature according to the UPGMA euclidean distance among populations. Most populations remained the same results between plots of the principal components analysis and cluster, and the relationship of all different populations could be discriminated by two ways. It will lay a good foundation for collection of germplasm resources and breeding fine variety.
