摘要
本文根据栋属植物形态特征,木材解剖特征和脂肪酸特征,对栋属植物进行聚类分析,其结果表明:栎属(Quercus L.)植物和青冈属(Cyclobalanopsis)是一个自然种群,应归为1属,建议栎属分为3个亚属,即青冈亚属(Subg.Cyclobalonopsis)高山栎亚属(Subg.suber)和落叶栎亚属(Subg.Quercus).这3个类群无论是在主要特征,还是在次要特征上,都表现出明显的区别,而高山栎亚属和青冈亚属的亲缘关系较近,落叶栎的分化程度较高,进化程度较高。
In this paper, the numerical taxonomy according to morphological, fatty acid and anatony characters have been studied by cluster analysis. The results show that the genus of Quercus should be further divided into 3 subgcnera: Oyclobalanopsis, Qucrcus, and Subcr. The 3 subgenera arc very different from each othc. cither in prima or in sccondcry characters. The closer relationship is found between Subg. Subcr and Subg. Cyclobalanopsis, and Subg. Quercus is more different iatcd and more advaneed in terms of evaluation.
