摘　　要：目的:对比研究5个不同产地及类型的细毡毛忍冬、淡红忍冬花粉粒的形态特征。方法:将花粉粒固定于载玻片上,漂洗,脱水,干燥,镀金后用扫描电镜观察。结果:3个不同类型的细毡毛忍冬花粉粒形态相似,但大小、表面凹凸及刺密度有区别;2个不同产地淡红忍冬花粉粒形态一致;细毡毛忍冬和淡红忍冬的区别主要是花粉粒表面颗粒状纹饰的大小,刺的多少及粗细。结论:为川银花的基源鉴定提供了参考依据。Objective:To study the morphological features of pollen grains of Lonicera similes Hemsl.and Lonicera acuminate Wall of 5 types from different producing places.Method:The pollen grains were fixed on the glass slide and observed under SEM after a serial of rinsing,dehydration,drying and gliding.Result:The pollen grains morphology of the 3 types of Lonicera similes Hemsl.were similar,but the size,surface concavo-convex and thorn density were different.The morphology of pollen grains of Lonicera acuminate Wall.from 2 different areas were almost same.The main differences between the pollen grains of Lonicera similes Hemsl and Lonicera acuminate Wall.were the size of exine granules sculpture,the number and size of thorn.Conclusion:The results might provide scientific basis for Chuanyinhua identification of origin.
