中文摘要：
采用去壁低渗法处理根尖细胞，得到了壳斗科13种植物分散较好的细胞中期分裂相，并分析了其中9种植物的染色体数目、随体数目和位置、核型公式、核型类型、臂比、相对长度、着丝点指数、核型不对称系数等内容。结果表明：除东南石栎属1B型外，其他均属2B型，K（2n）=24，在植物界属小染色体类型。
英文摘要：
Chromosome counts of 4 species and cytological characteristics of the top of roots of 9 species of the Fagaceae were investigated by using the method of wall degradation and hypotonic treatment, and the tests got clear mitotic metaphase of cells. The chromosome number, the number and position of SAT, the karyotype formulae, the karyotype classification, arm ratio, relative arm length,index of centromere and karyotypic anisomerous index,etc were analyzed. The results showed that the chromosome counts of 13 species are K（2n）=24 and Castanopsis tibetana, C. fordii, C. fabric, C. carlesii, C. fissa, C. jucunda, C. lamontii and Fagus longipetiolata are 2B,and Lithocarpus harlandii is 1B.
