内蒙古草原地区主要植物的花粉形态

A Primary Study on Pollen Morphology of Plants from Typical Grassland in Inner Mongolia .

采用扫描电子显微镜对内蒙古草原地区３１种主要植物的花粉形态进行了详细观察和描述。结果表明，不同科、属植物花粉的形状、大小、萌发器官类型和数量及表现纹饰均不相同；同一属内种间花粉的形状、萌发器官类型及纹饰类型等相同或相似，但在大小、萌发器官数量和细微纹饰等方面均有差异。

Pollen grains collected from 31 grassland species of typical grassland plants in Inner Monglia were observed by scanning electron microscope, The results showed that there were obvious differences among the pollen grains in terms of shape, size, germinator and surface structures,Itwas found that plants belonging to the same family displayed similarities in shap,germinator and type of surface structures. but the grains showed distinguised features in size, number of germinator and subtle surface structures.
