摘　　要：采用干燥器干燥和常规生物电镜样品制备两种方法,分别对白花泡桐、川泡桐、毛泡桐和台湾泡桐4种泡桐的花粉进行处理,用扫描电镜对两种不同处理后的4种泡桐花粉进行观察,结果表明:相比于常规生物电镜样品制备,直接采用干燥器干燥法制样,会导致花粉产生明显的变形。实验结果可为相关研究提供参考信息。The pollens of P.fortunei(Seem.)Hemsl.,P.fargesii Franch.,P.tomentosa(Thunb.)Steud.,and P.kawakamii Ito were examined by scanning electron microscope(SEM).Two different preparation techniques were used for the SEM samples by drying in desiccator or conventional method.The results showed that drying in desiccator directly leads to obvious deformations of pollen compared with the conventional method.The study provides some useful information for related science researchers.
