摘要: 在光学显微镜(LM)和扫描电子显微镜(SEM)下对6属15种真藓科(Bryaceae)植物的芽孢进行了形态特征观察。结果显示,真藓科芽孢形态多样,可以作为该科种间分类鉴定的重要标准。芽孢在不同发育时期,形态特征差异较大。无性芽孢在环境条件许可的情况下才会产生,产生芽孢的植株一般不易发生有性生殖。

Abstract: The morphological characteristics of gemma of 6 genera and 15 species in family Bryaceae were observed under the light microscope(LM) and scanning electron microscope(SEM). The results showed that the morphological characteristics of gemma could be look as a steady standard in identifying specimens. The discrepancy of morphological characteristics is great in different developmental phases of gemma. The appearance of gemma depends on favourable conditions and tuberiferous species are often sterile.
