- 摘要:
- 应用扫描电子显微镜对君子兰属9种植物花粉的形态、萌发沟、表面纹饰等性状和特征进行了观察。结果表明:君子兰属植物花粉形状皆为长球形,具单沟,远极沟,属于N1P3C3型花粉,具网状雕纹。花粉两端网眼急剧变小、变密,而花粉大小、网脊宽度、网眼直径等性状存在差异。聚类分析将供试试材分为3组,即大花君子兰组、垂笑君子兰组和窄叶君子兰组。
- Abstract:
- Pollen morphology and ultrastructure of 9 species of Clivia spp.had been examined by aid of the scanning electron microscope (SEM).The results showed that the pollen grains of Clivia were generally elliptic with mono-culpus and reticulate sculptures,which belonged to N1P3C3.The mesh of both ends of pollen became dramatically smaller and closer.The length of polar axis,equarorial axis,width of apertures and spine were different to some extent among these different species.From the cluster analysis,they could be classified into three groups,which were Clivia miniata,Clivia nobilis and Clivia gardenii.
