摘要: 利用扫描电镜技术观察了茶藨子属7个亚属12种植物的叶表皮微形态。结果显示:叶表皮细胞分为多边形和不规则形两种类型;垂周壁式样为平直—弓形、浅波形、深波形;叶表皮角质层多为光滑或较光滑,少有脊状纹饰或乳突状凸起;表皮毛分为单毛和腺毛;黑果茶藨子、水葡萄、臭茶藨子的叶表面均分布不同密度的盾状腺毛,支持将臭茶藨子系划分为臭茶藨子亚属;气孔器均为无规则型,形状为圆形或椭圆形,多数种类的气孔仅分布在下表皮。茶藨子属植物叶表皮微形态特征可为属内亚属划分及种间分类提供一定的依据。

Abstract: We observed the leaf epidermis characters in 7 subgenera, 12 species of Ribes L. using scanning electron microscopy(SEM). The epidermis cells were irregular polygon in shape. The patterns of anticlinal wall are straight-blow, sinuolate or sinuate. The cuticular layer of the leaf epidermis is usually smooth or nearly smooth, with few apophysis of mastoids. The trichomes are nonglandular hair and glandular hair. There are peltate glandular hairs in R.nigrum, R.procumbens and R.graveolens with different densities. We supported the treatment of the Ser. Nigra Pojark. as the subg. Coreosma. The stomata type is anomocytic in all observed species, the shape was round or oval. Most species were hypostomatic.

Key words: Ribes L., leaf epidermis, taxonomic, micromorphology
