摘要:

本文采用光学显微镜和扫描电镜对我国水蒒属植物14个居群的种子特征进行
    了研究。通过石蜡切片,在光学显微镜下观察了种子的内部结构。
    本文的研究结果,认为种间居群的差异比较显著,种内的居群特征比较类似,将我国水蒒
    属植物14个居群定为4种,即有尾水蒒Blyxa echinosperma (C. B. Clarke) Hook. f.,无尾水
蒒B. aubertii Rich.,光滑水蒒B. leiosperma Koidz.,水蒒B. japonica (Miq.) Maxim-。

Abstract:

The present paper reports seed characters of 14 populations in Chinese Blyxa,
examined using light microscope and scanning electron microscope.  The internal structures
of seeds were observed under light microscope after being prepared by paraffin section.
     The results show that differences between populations of different species are more dis-
tinct than between those within a species.  The 14 populations in Chinese Blyxa are grouped
into 4 species, i.e. Blyxa echinosperma (G. B. clarke) Hook. f., B. auberti Rich., B. leiosper-
ma Koid., B. japonica (Miq.) Maxim.

Key words: Hydrocharitaceae, Blyxa, Seed characters
