| 摘 要： | 经研究结果表明，青冈属Cyclobalanopsis与常绿栎类花粉形态特征基本上是一致的，
如花粉的形状和大小，萌发孔的类型以及外壁的结构均很相似。作者支持将青冈属归入栎属， 作为属下等级，即青冈亚属(Subg.Cyclobalanopsis)的分类处理。

| Abstract: | The present paper deals with pollen morphology of 19 species belonging to Cyclo-
balanopsis and of 31 species belonging to Quercus from China. All pollen grains were ex-
amined under light microscope and scanning electron microscope, and those of 4 species of
Cyclobalanopsis and of 8 species of Quercus were examined under transmission electron micro-
scope.
Pollen grains of Cyclobalanopsis are spheroidal or subspheroidal, 25.2(18.9-31.5) ×23.1
(16.8-27.3) μm in size. Mostly 3-colporoidate, rarely 3-colpate or 3-colporate. The exine is
2-layered, 1.1-1.9 μm thick, sexine thicker than nexine, finely granulate under LM, granula-
te, spinulate, verrucate under SEM.
Pollen grains of Cyclobalanopsis and of evergreen members of Quercus are very similar
to each other in size, aperture and ornamentation of exine, but there are some differences in
pollen grains between Cyclobalanopsis and deciduous members of Quercus. Therefore, Pollenmorphology supports the treatment of Cyclobalanopsis as a subgenus of Quercus. |
