摘要
通过对我国壳斗科7 属23 种及变种幼苗的外部形态及解剖学( 子叶、发育叶的形态、表皮细胞、气孔器、表皮毛等) 观察、比较和分析,认为有些特征在亚科或属级水平上较为稳定,有一定的分类学价值。据此提出了支持将本科划分成水青冈亚科Subfamily IFagoideae 和栎亚科Subfamily IIQuercoideae 两个亚科的观点,并讨论了水青冈属Fagus、三棱栎属Trigonobalanus、栗属Castanea、栲属Castanopsis、石栎属Lithocarpus、青冈属Cyclobalanopsis 和栎属Quercus 7 个属划分的合理性及一些分类群之间的亲缘关系。
This paper deals with the morphology and anatomy of seedlings in 22 species and 1 variety of Fagaceae (7 genera) in China.Most of these characters of seedlings are of systematic significance in the family.Based on these seedling characters,we suggest that Fagaceae is divided into subfamily I Fagoideae and subfamily II Quercoideae.The relation ship of taxon is also discussed.
