摘要: 用扫描电镜观察到了国家一级保护植物云贵水韭(Isoetes yunguiensis)大孢子新的形态特征:孢子表面具球状颗粒;网状纹饰浅而细密;网状纹饰浅而细密且体积显著增加等。认为古老的异孢、有叶舌类植物的大孢子在大小、纹饰、裂缝等三方面都能发生显著变化。

关键词: 云贵水韭, 大孢子, 形态特征

Abstract: New megaspore morphological characteristics of the protected plant—Isoetes yunguiensis were observed using scanning electron microscope (SEM). The result indicates: globular granule on megaspore surface; inapparent reticulate ornamentation; inapparent reticulate ornamentation with big size. Megaspore of the old ligulate heterosporophyte are easy to significantly change in size, ornamentaion and fissure.

Key words: Isoetes yunguiensis, megaspore, morphological characteristics
