对华南苦苣苔植物9个属16个种的花粉进行了扫描电镜的观察和研究.结果显示其花粉形态大多为长球形,少数呈圆球形、超长球形,外壁纹饰为网状纹饰、疣状纹饰、粗糙纹饰、颗粒-穿孔纹饰和刺状-穿孔纹饰.研究结果表明,花粉外壁纹饰特征在苦苣苔科的分类与系统研究方面可能具有较大价值.
Pollen morphology of some species of Gesneriaceae from Guangxi were examined under scanning electron microscope( SEM). The most of pollen grains' shape is prolate,a few is sculptured or perprolate,but the exine sculpture of pollen grains has more types: reticulate,verrucate,scabrate,granulate-perforate and microechinateperforate. The type of sculpture may have some significancesin the systematic arrangement of Gesneriaceae.
