摘要: 借助扫描电镜对采自全国主要银杏分布区的33株银杏Ginkgo biloba古树雄株的花粉外壁形态特征进行观察,发现银杏花粉外部形态基本一致,赤道面观为橄榄形或梭形,侧面观为长椭圆形,萌发沟与花粉近等长。但在光滑程度、纹饰特征、条纹分布的规律性、微孔情况等方面存在比较明显的差别。结果表明,银杏花粉形态具有多样性和复杂性。图1表1参11Abstract: The pollens of 33 ancient male ginkgo trees which came from main distribution areas of Ginkgo biloba was observed through scanning electron microscopy. The results showed that the pollen had approximately similar outside morphology,and they were all olive shaped and had a bourgeon channels which was about the length of pollen. There were significant differences in smooth,ektexine texture,and pores condition of pollen. The morphology of ginkgo pollen was complex and diverse.[Ch,1 fig. 1 tab. 11 ref.]
