中文摘要:目的：通过对辽宁产老鹳草属植物花粉形态进行观察，达到同属植物区别鉴定的目的。方法：利用扫描电镜（SEM）对辽宁老鹳草属植物花粉的大小、形态、表面纹饰、萌发沟等特征进行观察、比较和分类。结果：7种老鹳草花粉均为近球形，外壁均为棒状-网纹复合纹饰，而在花粉粒大小、萌发沟大小、棒状形态及大小、网眼均匀程度及大小上均有差异。结论：实验结果对老鹳草属植物种的划分和鉴定具有一定的指导意义，同时为揭示老鹳草属植物种质资源多样性奠定了基础。

Comparative study on pollen morphology of Geranium in Liaoning Province

Abstract:Objective：to observe the pollen morphology of Geranium species in Liaoning Province，and to achieve the purpose of differential identification of the same genus.Methods：the pollen size，morphology，surface ornamentation and germination ditch of Geranium species in Liaoning province were observed，compared and classified by scanning electron microscope（SEM）.Results：The pollen of seven kinds of Geranium species were nearly spherical，and the outer wall was rod-like composite pattern，and there were differences in the size of the pollen，the size of the germination ditch，the rod shape and the size，the degree and the size of the mesh.Conclusion：the experimental results have certain guiding significance for the division and identification of Geranium species，and lay a foundation for revealing the diversity of Geranium resources.
