摘　　要：利用电镜扫描方法对山东济南栽培和野生的槐属(SophoraL.)3种1变型的花粉进行亚显微形态结构观察和研究。结果显示,该属花粉为长球形,具3孔沟,而花粉外壁雕纹、孔沟的形态结构特征明显表现出种与种之间、种与变型之间的差异,可以作为种间分类的依据。Pollen sub-micromorphology of 3 species and 1 form of Sophora L.cultivated and wild in Jinan,Shandong were examined and studied under scanning electron microscope (SEM).The results showed that the pollen grains of Sophora L.are prolate spheroid with 3-colporate.The pollen exine sculpture and the morphology of colporate vary with different species and form.The difference can be served as a basis for the classification of the species of Sophora L.
