| 摘 要： | 藓纲包括３个亚纲（Ｂｒｏｔｈｅｒｕｓ,１９２４－１９２５）。泥炭藓亚纲、黑藓亚纲,真藓亚纲,全世界约１００个科,近８００属,约１５０００种。藓类的传孢类型和藓类植物系统演化有密切关系。我们认为传孢不同类型,直接反映了他们的演化程度。我们根据藓类孢子体的分化、蒴齿分化与其机能,分为５种传孢类型。即腐媒传孢型,风媒孢型,汽－风媒传孢型,水媒传孢型,和虫媒传孢型等５种。根据它们的演化程度比较,我们提出了

include three Subclasses(Brotherus,1924～1925)Sphagnidae, Andreaeidae and Bryidae, which are composed of
about 100 families and 800 genera in the world. Our researches indicated that the types of
spore dispersal has an important significance in the evolution of mosses. Based on the
studies of sporophyte, peristome teeth and the individual development of mosses, 5 types
of spore dispersal can be inducted, that is decay dispersal, wind dispersal, vapour-wind
dispersal, water dispersal and insect dispersal. Furthermore, the relationship between the
spore dispersal and evolution is discussed in detail. A newly evolution system of families
of mosses is presented. |
