From: The synergistic effect of Selenium (selenite, –SeO3 2−) dose and irradiance intensity in Chlorella cultures

Fig. 4

Changes of variables Fv/Fm (a) rETRmax (b) and Ek (c) were calculated from rapid light-response curves (see Fig. 3) caused by various Se concentrations (2.5, 8.5 and 25 mg Se per g of DW) after 72 h of experiments. The effect of various light intensities of 250, 500 and 750 µmol photons m−2 s−1 in the presence of exposure to 16 mg g−1 selenium on Fv/Fm (d) rETRmax(e) and Ek (f) variables is shown after 72 h. Control means no Se addition
