Responses of nine bryophyte and one lichen species from different microhabitats to elevated UV-B radiation

Abstract

Chlorophyll fluorescence parameters (Fv/Fm, RFd) of nine bryophyte and one lichen species were investigated after prolonged exposure to elevated UV-B radiation. The majority of the investigated bryophytes showed a prompt or inducible tolerance to increased UV-B irradiation. Among the investigated species high degree of UV-tolerance coincides with strong desiccation tolerance.
