摘要:

本文作者对国产的Castanea、Castanopsis Lithocarpus三个属花粉,进行了光学显微
    镜、扫描电镜、透射电镜下的观察和系统研究,结果表明:三个属的花粉形状、大小、萌发孔、外
    壁纹饰及其结构都非常相似,与植物外部形态的特征相吻合。故作者支持将这三个属归为一
    个亚科即栗亚科Castaneoideae。

Abstract:

The present paper describes the pollen morphology of 45 species of the sub-
family Castaneoifeae (including genera  Castanea, Castanopsis  and Lithocarpus) from China.
The pollen  grains were all examined with light microscope, scanning electron microscope and
transmission electron microscope.
       Pollen grains of the subfamily are prolate, subprolate or perprolate, (14.7-23.1)× (8.4
-18.9) μm in size, 3-colporate, the exine in 2-layered, 0.9-1.9μm thick, indistinctly orna-
te, striate-rugulose  or crass-striate, sexine  and nexine almost equal  in thickness,   the sexine
consists of  tectum, bacules and endonexine under TEM.
      On the  basis of  very  similar pollen shape,  pollen size, type of aperture and exine struc-
ture and also other characteristics of plant morphology of the genera Castanea, Castanopsis and
Lithocarpus, the present authors tend to support the opinion that they all fall into the same
subfamily, Castaneoideae.
