摘要/Abstract

摘要： 通常,把栎属(Quercus L.)中的落叶种类称为落叶栎。在经典分类学方面,植物分类学家对我国落叶栎进行了不少的研究工作^[2,5,6,8,13]。从这些研究中看出落叶栎种之间的天然杂种并不罕见,而且一些遗传学研究和细胞学研究征明了这些天然杂种的可孕性^[8,9,11,12]。由于天然杂交现象的存在,落叶栎种类之间的形态特征表现得错综复杂,种间界限具有很大的连续性,给种类的确定及种间亲缘关系的研究带来很大困难。本文采用聚类分析(Cluster analysis)方法和染色体组型分析方法对我国落叶栎进行分类学研究,拟为今后对整个栎属乃至整个壳斗科(Fagaceae)的分类学研究提供一些新的基本资料。

Abstract: This is a taxonomic study on the deciduous oaks of China by means of cluster and karyotype analyses. 1. By the cluster analysis to 25 species of the deciduous in China, 4 new taxa which have recently been published are further tested and their specific place in all the deciduous oaks are defined, and the relationship is quantified among the 25 oaks which are divided into two groups including daimyo oak group and sawtooth oak group. 2. The chromosome karyotypes of 12 main species of the deciduous oaks in China and common oak introduced are studied. The chromosomes of all the species exammed are 2n=24,and consist of metacentric and submetacentric chromosomes. The chromosomes from 1.14μ to 3.46μ in length. The 13species can be divided into three types:daimyo oak-type,sawtooth oak-type and common oak-type.
