Micro-morphological Characteristics of Nut Epidermis of Scirpus (Generalized) from Shandong
-
摘要: 利用光学显微镜和扫描电镜对山东产藨草属Scirpus L.(广义)11个类群的坚果果皮微形态进行了观察和研究,该属11种的微形态可以分为4个类型, 即:Ⅰ波形网状纹饰,Ⅱ网瘤状复合纹饰,Ⅲ平滑型纹饰,Ⅳ横长网状纹饰。研究结果支持将藨草属Scirpus L.(广义)中藨草亚属Subgen.Scirpus的具球茎藨草组Sect.Bolboschoenus Ascheron、藨草组Sect.Scirpus和丝状刚毛藨草组Sect.Trichophorum (Pers.) Darl.分别提升为三棱草属Bolboschoenus (Ascheron) Palla和藨草属Scirpus L.以及将藨草属Scirpus L.(广义)中秆苞藨草亚属Subgen.Isolepis的湖边藨草组Sect.Schoenoplectus Reichb.和藨草组Sect.Actaeogeton Reichb.提升为水葱属Schoenoplectus (Rchb.) Palla的处理意见。认为应在水葱属下设立湖边水葱组Sect.Schoenoplectus(Reichb.)F.Z.Li & L.N.Liu,藨草组Sect.Actaeogeton(Reichb.)F.Z.Li & L.N.Liu,剑苞藨草组Sect.Ehrenbergii F.Z.Li & L.N.Liu。支持将青岛藨草Scirpus trisetosus Tang et Wang作为藨草Scirpus triqueter L. 异名处理的意见。并对山东藨草属种类的学名进行了订证。Abstract: The micro-morphological characteristics of nut epidermis of 11 species of Scirpus from Shandong were studied under light microscope and scanning electron microscope (SEM).The micro-morphological characteristics of the nut epidermis were divided into four types: Ⅰ Waveform reticulate sculpture,Ⅱ Tuberculate-reticulate sculpture, Ⅲ Smooth sculpture,and Ⅳ reticulate sculpture.The evidence supported that section Sect.Bolboschoenus Ascheron,Sect.Scirpus & Sect.Trichophorum (Pers.) Darl.,which belongs to Subgen.Scirpus should be promoted to Bolboschoenus (Ascheron) Palla,Scirpus L..Sect.Schoenoplectus Reichb.& Sect.Actaeogeton Reichb,which belongs to Subgen.Isolepis should be promoted to Schoenoplectus (Rchb.) Palla.Sect.Schoenoplectus (Reichb.) F.Z.Li & L.N.Liu,Sect.Ac-taeogeton (Reichb.) F.Z.Li & L.N.Liu,Sect.Ehrenbergii F.Z.Li & L.N.Liu should be retained in Schoenoplectus (Rchb.) Palla.Evidence of the micromorphological characteristics of the fruits supported that Scirpus trisetosus Tang et Wang should be treated as a synonym of Scirpus triqueter L.Eight species of plants names of Scirpus from Shandong have been amended.
