【摘要】 应用扫描电子显微镜 ,观察了 15种苔草属复序苔草亚属植物果皮的微形态特征。结果表明 ,复序苔草亚属植物果皮的微形态性状多种多样 ,可以为系统学研究提供较丰富的信息 ;并且在所观察的种类中 ,果皮的微形态特征在种内很稳定 ,种间存在不同程度的差异 ,某些近缘种也可表现出一定的相似性。因此 ,上述特征可以做为探讨种之间的分类及亲缘关系的参考。更多还原

【Abstract】 The achene epidermis of 15 species of Carex subgenus Indocarex was observed with SEM. The micromorphological characters of achene epidermis of the subgenus are varied, can provide numerous informations for systematic study. The micromorphology of achene epidermis is stable at specific level and different from each other among species, but related species display certain similarity. Therefore, the micromorphological characters are valuable in classifying species and determining the relationships between species.更多还原
