摘要: 本文对中国东北牛儿苗科(Geraniaceae)二属(太阳花属Erodium, 老鹳草属(Geranium)计14种(species)1变种(Variety)和1变型(form)植物的种皮亚显微结构(SEM)及种子形态进行了研究.结果表明, 太阳花属与老鹳草属植物无论从种子形状, 长宽比, 还是种皮初级雕纹及次级雕纹形态都表现出明显差异。在老鹤草属下种及种下等级的鉴定和划分上, 种皮微形态及种子形态特征提供了大量有价值的信息。

Abstract: In this psper, the seed coat submorphology and seed morphology of Geraniaceae(2 genus.14 species 1 variety and 1 form) in Northeastem China were studied.the results show that there are many differences between genus Erodium and genus Geranium either seed-coat sculpture (primary and secondary sculpture) or seed morphology (seed shape.length/width ratio). Seed and seed-coat morphology provsde a lot of key information with taxonomy of genus Geranium.The present seed coat and seed morphological classificationis is in accordance with Kitagawa's svstem of Geraniaceae, which was done using other morphological characters.

Key words: Geraniaceae, Submorphology, Sculpture, Seed morphology
