【Abstract】 Spore germination and protonema growth of 10 species of mosses are sdudied at 16℃～18℃ in response to Knudoson C and running water. The materials studied here are gotten from various habitats in Hebei Province. They are Tortula mucronifolia Schwaegr., Tortula schmidii (C. Muell.) Broth., Weissia controversa Hedw., Physcomitrium eurystomum Sendtn., Venturiella sinensis (Vent ex Rabh.) C. Muell., Lindbergia sinensis (C. Muell.) Broth., Amblystegium serpeus (Hedw.) B. S. G., Brachythecium buchananii (Hook) Jaeg., Entodon macropodus (Hedw.) C. Muell. and Entodon okamurae Broth. The spores of ten species of mosses well develop and their normal protonemata form. The process of the spore germination and protonema growth are illustrated and taken microphotographs. The result shows that the time of spore germination is 3～10 days, the germination pole is 1～2 poles, sometimes 3～4 poles. Besides, the capability of spore germination is influenced by temperature, pH, illumination and so on. The protonemata are consisted of 3 types, namely, the chloronemata?caulonemata and rhizoides. According to the characteristics of protonemata, the spore germinnation of these mosses are classified into 3 types, which are Funaria-type, Bryum-type and Macromitrium-type.更多还原
