以福建省4个柚子品种‘文旦柚’、‘坪山柚’、‘琯溪蜜柚’和‘红肉蜜柚’为试材，通过电镜扫描观察花粉外部形态、纹饰及萌发器官类型，并进行比较分析。试验结果表明，4个品种的花粉形状均为圆球形，大小为23.40～25.82μm ×26.05～28.00μm ；外壁纹饰均为细网状；萌发器官均为孔沟类型。其中‘琯溪蜜柚’和‘红肉蜜柚’花粉形态、纹饰及萌发器官较一致，其外壁纹饰相对简单，网脊平宽光滑，网眼较浅，具4条或5条孔沟（而‘文旦柚’和‘坪山柚’只有4条）。花粉形态的初步研究旨在为进一步的柚子鉴定及系统分类提供依据。

The pollen of four pomelo cultivars (Wendan ,Pingshan ,Guanxi and Hongrou) was observed with scanning electron microscopy for comparing their pollen morphology ,exine ornamentation and germinal aperture . The results showed that the pollen shape of four pomelo cultivars was all in sphere ,and the size was 23.40-25.82μm × 26.05-28.00μm ,the exine pattern was fine reticulation and the germinal aperture was all in colporate .The pollen of ‘guanximiyou’ and‘hongroumiyou’ were similar in morphology ,the murus of exine was smoother ,the mesh was shallow and with 4 or 5 of colporates (while wendanyou′and pingshanyou′only 4) .The data of the pollen morphology could be used further in the identification and systematic classification for pomelo varieties .
