内蒙古野豌豆属(Vicia L.)植物的花粉形态研究

STUDIES ON THE POLLEN MORPHOLOGY OF THE GENUS VICIA L. IN INNER MONGOLIA

利用扫描电子显微镜观察了内蒙古境内１３种野豌豆属植物的花粉形态，系统报道了１２种植物的花粉形态．观察结果表明，野豌豆属植物花粉的形状、萌发孔及外壁饰纹等特征在种内是稳定的．此外，利用花粉形态特征，对复合种的分类进行了进一步的探讨．

In this paper,the authors examined the pollen morphology of 13 species of Vicia in Inner Mongolia by scanning electronic microscope and systematically reported the pollen morphology of 12 species of Vicia in Inner Mongolia for the first time.The result shows that the pollen Vicia is stable on the shape,size and the ornamentation of exine in a species.On the basis of the characteristics of the pollen morphology,the authors further discussed the classification Vicia amoena Complex and V.venosa Complex.
