Fig. 5

Rapid chlorophyll fluorescence kinetics of Chlorella cultures treated with various Se concentrations (2.5, 8.5 and 25 mg Se per g of DW) at 250 μmol photon m−2 s−1 after 48 h (a) and 72 h (b) of experiment. The Chlorella cultures also were exposed to various light intensities (250, 500 and 750 µmol photons m−2 s−1, respectively) in the presence of 16 mg Se g−1 DW for 48 h (c) and 72 h (d) (control—no Se addition)
