摘要
对华北骆绒藜，、驼绒藜和内蒙驼绒藜１０种供试材料花粉粒进行的研究结果表明，其花粉粒均为球形，具散孔，分布均匀，孔圆形或近圆形。外壁上具颗粒状纹饰。三种植物花粉粒在大小、孔的数量、孔间距、孔的直径，外壁内、外层的厚度及其外壁纹饰上均有差异。
ollen grains collected from 10 plants of three Ceratoides species were examined for their morphological characteristics.All grains are spheroidal in shap Evenly distribut-ed apertures are found on the surface of pollen grains.Some differences are found be-tween the species in terms of size,aperture number,aperture distribution,aperture size,thickness of the pollen coats,and stria structure of the pollen grains.
