The germination of the spores of Bryum pseudo-triquetrum was much reduced after irradiation with germicidal ultraviolet light. This reduction was photoreactivated by the irradiation with monochromatic light at 4365 and 4610Å but not at 4070 or 3600Å. At 4610Å, the reactivation rate increased with illuminating time and saturated beyond 60 minutes. The reactivation occurred at 25°C, but not at 2°C. These results suggest that the observed photoreactivation is of the enzymatic nature.
