In this paper, we report growth characteristic of Scopelophila cataractae, which is known as copper moss. First, we examine how to obtain axenic plants because that will enable us to control various conditions surrounding plants by artificial means. Next, we investigate the influence on growth of S. cataractae by the kind of medium, the changing pH, and the concentration of copper in a medium using two measurements: a ratio of the protonemal area and the chlorophyll concentration. The results revealed that the growth behavior’s dependence on the concentration of copper differed by the kind of medium in S. cataractae. With further research in the future, these results can contribute to an elucidation of the mechanisms of copper tolerance in S. cataractae.

Key Words： Scopelophila cataractae / copper moss / plant tissue culture / chlorophyll concentration
