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,风媒传孢型,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,我们提出了一个以科为单位的演化系统表。

Abstract: Musci 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 stud-ies 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.
