摘　　要：运用扫描电镜对分布于青海省的葱属植物5种9个自然居群的种子形态进行观察。结果表明:葱属植物种子颜色为黑色,属中型种子,其形态为卵形或近球形,表面纹饰均为梯形,但突起的种皮细胞在形态、排列及次级纹饰等方面存在种间甚至种内差异,且较为显著,具有重要的系统学意义。Seed shape and micromorphology of nine natural populations from five Allium species were observed by SEM. The results show that the seeds are black, moderate in size and ovate or subglobose in shape. The ornamenta- tion of seed coat is scalariform. However, the shape, arrangement and secondary sculpture of convex testa cells have predominant differences both among and within species, providing some evidence for classification of Alliurn.
