摘要
本文应用光学显微镜及扫描电镜对泡桐属五种植物花粉的形态进行了观察,结果表明,该属植物花粉为中等大小,近球形均具三孔沟,表面纹饰为网状.5 个种之间在花粉大小,网状纹饰,内孔明显与否存在差异,说明花粉的一些形态特征指标可以作为泡桐属植物种之间分类的重要依据.
In this paper, pollen grains of 5 xpecies of the genus Panlownia were examined under light subspheroidal, 3-coporate and reticulate exine ornamentation. But differences exist in erms of the size of pollen, reticulate sculpture and the distinctive extent of the endo-porus, which indicates that the pollen morphology investigated above may serve as a taxonomic character in Paulownia
