摘要: 利用光学显微镜和扫描电镜对东北异极藻科植物3属8个分类单位即:异极藻属(Gomphonema)2种2变种1变型:细异极藻箭头变种G.sabtile var.saggita (Schum..) Cl.K.,缢缩异极藻头状变种意大利变型G.constrictum var.capitatum f.itallica Mayer.,柔弱异极藻G.tenellum Kü tz.,半孔异极藻G.semiapertum Grun.长异极藻延长变种G.vastum var.elongata Skv.;异楔藻属(Gomphoneis)2种:具点橄榄异楔藻G.olivaceoides (Hust) Carter&Bailey-Wattrs,四点异楔藻G.quadripuntatum (φstr.) Dawson ex Ross&Sims.;双楔藻属(Didymosphenia)1种:双生双楔藻D.geminata (Lyngb.) M.Schmidt进行了分类学的比较研究,初步探讨了分类学及生态分布上的问题。并首次报道了中国异极藻科的一些新记录。

Abstract: In present paper, 3 genera and 8 taxa of Gomphonemaceae from Northeastern China are studied by light and scanning electron microscope.They are:Gomphonema:G.subtile var.sagitta (Schum.) Cl., G.constrictum var.capitatum f.itallica Mayer., G.tenellumKü tz., G.semiapertum Grun., G.vastum var.elongata Skv.;Gomphoneis:G.olivaceoides (Hust) Carter&Bailey-Watts.G.quadripunctatum (φstr.) Dawson ex Ross&Sims.;Didymosphenia:D.geminata (Lyngb.) M.Schmidt.The problem of taxonomy and ecological distribution are discussed preliminarily, and some new taxa are first reported from China.
