| 摘 要： | 目的]研究几种常见樟科植物花粉的形态特征。方法]利用扫描电子显微镜对樟科4属5种植物的花粉表面微形态进行了观察和比较。结果]樟、浙江楠和月桂的花粉均为近球形,直径约20～32μm,表面遍布刺突纹饰,其中月桂花粉表面可观察到成对的小穿孔;山胡椒和香叶树的花粉极面观为三裂椭圆形,具有3个较深的萌发沟,沟长达两极,花粉大小分别为50×40和55×42μm,花粉表面密布明显的小孔穴。结论]该研究可为樟科植物花粉的研究提供更多孢粉学依据。

| Abstract: | Objective] The morphological characteristics of pollen of several Lauraceae plants were studied.Method] By means of scanning electron microscopic(SEM),the surface microtopography of pollen of five Lauraceae plants belonging to four genus were observed and compared.Result] The pollen of Cinnamomum camphora,Phoebe chekiangensis and Laurus nobilis was near spherical,with the diameter of about 20-32 μm,and there were ornamentations and spikes on the surface,while small coupled perforations could be found on the surface of pollen of Laurus nobilis;the pollen of Lindera glauca and Lindera communis was 3-lobed ellipse in polar view,with three deeper germinal furrows extending to the poles,and their pollen sizes were 50×40 and 55×42 μm,with small dense holes on the surface of pollen.Conclusion] Our study could provide more palynology evidences for the pollen research of Lauraceae plants. |
