摘要: 本文应用光学显微镜及扫描电镜对国产32种堇菜属植物的花粉形态进行了观察,结果表明,在光学显微镜下,除V.tricolor L.外,堇菜属植物的花粉形态比校一致,对本属的分类意义不大。在扫描电镜下的花粉外壁纹饰亦表明本属是一个较为自然的类群。但国产四亚属之间的花粉在外壁纹饰,颗粒的多少和有无,穿孔的多少和有无等方面存在着较明显的差异,而在亚属内则分化校小。支持了Juzepchuk(1949)和王庆瑞(1991)的分类处理。

关键词: 堇菜属, 花粉形态

Abstract: Pollen grains of 32 species of the genus Viola in China were examined under LM and SEM. Their morphological characters are described here. Pollen morphological characters under LM are similar except V. tricolor L. under SEM, the exine of pollen have some difference among the four subgenus of Viola. The evidence from pollen morphological characters supports Juzepchuk's (1949) and Wang Qing-rui's (1991) treatments which divided the Viola into four subgenus.

Key words: Viola, Pollen morphology
