摘要
利用扫描电子显微镜对小檗科淫羊藿属(EpimediumL.)34种及亚(变)种44个花粉样品进行了观察和研究。该属植物花粉的外壁纹饰有由不规则条纹状突起到穴状、穴网状,再至网状或条网状演化的趋势,其中包括了穴(网眼)由少到多、由小到大;网脊表面具微刺至平坦的演化方向,与形态性状的演化基本一致,具有重要的分类价值。
Forty-four pollen speciemens from thirty-four species and subspecies or varieties of the genus Epimedium (Berberidaceae) were examined by means of election microscope. The result revealed that the exine ornamentation evoled from irregularly-arranged stiate with small tips to foveolate, foveolate-reticulate, and to reticulate or striato-reticulate type, along with the reticulate tectum from having small tips on it to psilate. Its taxonomic significance among them is discussed.
