项目摘要
As the basic data of this research, all moss species recorded from Japan were listed. This list is comprised of 1180 species belonging to 321 genera. Moss flora of Japan is remarkably rich as it contains almost the same number of species with that of whole North America.The affinities of the Japanese moss flora with those of eastern North America and western North America were investigated. The list of moss species of the eastern North American element in the Japanese moss flora is revised to 33 species and a list of 11pairs of vicarious taxa of mosses in these two regions is provided. Possible speciations of these species were discussed.Structure and movement of peristome filaments of many Japanese species of the genus Fissidens were studied. All species of the subgenera Aneruron and Fissidens examined show hygroscopical movement of peristome filamtnes. The filaments are spirally thickened and not nodose. On the contrary, all species of the subgenera Serridium and Pachyfissidens have nodose peristome filaments and do not show hygroscopic movement. Differentiation of peristome teeth is important for the classification of subgenera of Fissidens.Various types of vegetative diaspores of Japanese mosses were examined. They are classified into two groups, propagules and gemmae. Vegetative diaspores are important for distribution of mosses. Speciation of mosses based on vegetative diaspores was discussed.
作为本研究的基础资料,列出了在日本记录到的所有苔藓种类。该名录共有321属1180种。日本的苔藓植物群非常丰富,其种类几乎与整个北美相同。研究了日本苔藓植物区系与北美东部和西部苔藓植物区系的亲缘关系。本文将日本苔藓植物区系中北美东部元素的苔藓种类列表修订为33种,并提供了这两个地区的11对苔藓替代分类群列表。讨论了这些物种的可能种类。研究了日本许多种稻属植物花丝的结构和运动。所有亚种的锦鲤亚属和锦鲤亚属都表现出吸湿运动。花丝螺旋状增厚,不结瘤。相反,Serridium亚属和Pachyfissidens亚属的所有种都有结状的peristome细丝,不表现出吸湿运动。岩壁齿的分化对裂门亚属的分类具有重要意义。研究了日本藓类植物的各种营养增生类型。它们分为两组,繁殖体和胚芽。营养性弥散孔对藓类植物的分布具有重要意义。讨论了基于营养性孢子的苔藓物种形成。
