摘要: 用扫描电子显微镜观察了刺五加和无梗五加花粉的亚显微形态特征。花粉粒的赤道面观呈近圆形,极面观呈三裂圆形,具三孔沟。无梗五加、刺五加雄株的花粉表面纹饰为网状;刺五加两性株的花粉的表面纹饰亦呈网状,但有些花粉网脊不连续。无梗五加的花粉粒大小为26.5μm×27.4μm;刺五加雄株的花粉粒大小为21.1μm×22.1μm;刺五加两性株的花粉粒大小约为21.6μm×23.9μm。研究结果表明,无梗五加和刺五加雄株花粉的亚显微形态特征支持传统的属级和种级水平的分类;刺五加两性株某些花粉粒亚显微形态的独特表现可能与其发育不正常有关。

Abstract: The pollen submicroscopic morphology of Eleutherococcus senticosus and E. sessiliflorus was examined with scanning electron microscope (SEM). The pollen grains of the two species are round in equatorial view, 3-labed-rounded in polar view and 3-colporate. The pollen exine ornamentation of E. sessiliflorus and that of male E. senticosus is with reticulate; the exine ornamentation of bisexual E. senticosus pollens is also with reticulate but the murns of some pollens are discontinued. The polar axis×equatorial axis of pollen grains of E. sessiliflorus is 26.5μm×27.4μm; and that of male E. senticosus pollen grains is 21.1μm×22.1μm; that of bisexual E. senticosus pollen grains is about 21.6μm×23.9μm. The characteristics of pollen submicroscopic morphology of the two species supports the traditional taxonomy for the genus and the species level; and the distinguishing features of some bisexual E. senticosus pollens may be related to their irregular development.
