Abstract: Gemma culture and protonema growth of Barbula indica (Hook.) Spreng in response to meliorative knop, authors study the whole process and take photoes. The results show that its gemma germinates after 3~4 days;10 days later, chloronemata, caulonemata and rhizoides begin to differentiate; 18 days, the branch top cells of caulonemata differentiate into unicellular or multicellular gemmas; Nearly 40 days, bud primordium appears on caulonemata and develops into callow gametophyte. In the end of this paper, the characteristics of gemma development, and phyoiological ecology and gametophyte formation are analysed and discussed.

Key words: Barbula indica, gemma, development
