摘　　要：通过扫描电镜(SEM)对贺兰山5种国家级重点保护植物的花粉形态进行了详细的观察描述,结果表明,这5种植物的花粉形态均与其所属科或属的总体性状相一致,而同属豆科(Leguminosae)的沙冬青(Ammopiptanthusmongolicus)和野大豆(Glycine soja),其花粉形态主要在大小和表面纹饰的细微性状存在差别;蒙古扁桃(Prunusmongolicus)的花粉形态符合蔷薇科(Rosaceae),除地榆属(SanguisorbaL.)外的总体特征;贺兰山丁香(Syringapinnatifoliavar.alashanensis)的花粉形态与木犀科(Oleaceae)丁香属(SyringaL.)其他种的形态大致相同,但纹饰表现非常强烈;四合木(Tetraena mongolicus)在我国是蒺藜科(Zygophyllaceae)的单种属植物,其花粉形态与蒺藜科其他属植物的花粉形态差别较大.Pollen morphology of 5 species of national emphasis protection plants in Helan mountain was examined and described comprehensively under scanning electronic microscope（SEM）. The result shows that the pollen morphology of 5 species plants are same with their section or generic, but Arnrnopiptanthus mongolicus and Glycine soja which all belong to Leguminosae have small differences in size and surface texturing~ the pollen morphology of Prunus rnongolicus accord with Sanguisorba L. of Rosaceae＇s collectivity character; Syringa pinnatifolia vat. alashanensis are similiar with the other specifics in Syringa L. of Oleaceae, but the pollen morphology of texturing exhibition is very intensively; Tetraena mongolicus is Zygophyllaceae＇s single category plants in China, its pollen morphology have obvious differences from the other category plants in Zygophyllaceae.
