| 摘 要： | 利用扫描电镜对莲属植物的花粉形态进行观察研究。结果表明:所有测试材料的花粉形态极为相似,赤道面观均为长椭圆形,极面观均为三裂圆形,且都具有3条萌发沟。外壁纹饰基本为脑状纹,且外壁纹饰存在着深浅的变化。这些花粉的形态特征为莲的分类学和系统发育学研究提供了新的证据。 |

| Abstract: | Pollen morphology of Nelumbo was examined by using SEM(scanning electron microscope).The results showed that the pollen grains of these samples were similar in the shape of pollens,which were all prolate spheroid with three colporate.However,there were some differences among these specimens on the size of volume and sculpture.The pollens had cerebroid sculpture on their surface,which were differential in the gradation of the sculpture among Nelumbo accessions.These morphological characters of pollen could be the new evidence for taxonomy and phylogenetic researches in Nelumbo. |
| Keywords: | Nelumbo pollen morphology scanning electron microscope |
