N2 - Slow chlorophyll fluorescence kinetics with quenching analysis, rapid light-response curves of photosynthesis were used to assess response of two lichen species to temperature fall (from 22 to 5 degC) and gradual thalli desiccation (from full hydration (100%) to dry state (0 % of relative water content)). Desiccation to 0-45% led to the decrease in Fv/Fm and PS II quantum yield, while qP was unaffected. Desiccation also promoted qN (non-radiative energy dissipation processes). In the species studied, temperature fall induced decrease in PS II quantum yield and the rate of gross photosynthetis.
