The effect of controlled desiccation on the effective quantum yield (ΔF/Fm′) of photosystem 2 as regularly measured with a PAM 2500 during the experiment (400–500 min) in the four Klebsormidium isolates BIOTA 14614.7 (African Strain A), BIOTA 14,613.5e (African Strain B), BIOTA 14614.18.24 (African Strain C) and SAG 384-1 (Arctic Strain) (n = 4, mean value±SD). Effective quantum yield values of control algae under 40 μmol photons m−2 s−1 PAR was determined as 0.54–0.59 and standardized to 100% for better comparison. All measurements were done at 22 ± 1 °C.
