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。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.
