七种中国珠藓科植物孢子形态研究

Spore Morphological Observation for Seven Species of Bartramiaceae in China

作者通过光学显微镜和扫描电镜观察了7种珠藓科植物的孢子。观察结果显示:孢子近极薄壁区的有无、形状及外壁纹饰的细微结构等方面,在属间和种间存在一定的差异。与此同时,这7种珠藓科植物的孢子在大小、外壁厚度等方面表现出较大的相似性。本研究也显示孢粉学资料可以为研究珠藓科系统演化提供可靠的依据。

The spores of 7 species in Bartramiaceae from China were observed by light microscope （LM） and scanning electron microscope （SEM）. ＂The result shows that there are some differences among 7 species on the proximal face, the exine omamention and shape. By contrast, there are some similarity on size and thickness of exine. These observation will increase new information of spores for systematic analysis of Bartramiaceae.
