Table 1 Changes of variables of the maximum PSII quantum yield, Fv/Fm, maximum electron transport rate rETRmax and the irradiance saturating photosynthesis Ek were estimated from rapid light-response curves (Additional file 1: Figure S1) monitored at midday on Day 1, 4 and 7 during a 7-day experiment in the presence and absence of Se

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

  1. Changes of variables Vj and Vi were calculated from fast fluorescence induction kinetics (Fig. S2) monitored on Day 1, 4 and 7 during a 10-day experiment in the presence and absence of Se. Vj reflects a reduction of Q A (photochemical phase) while Vi is thought to correspond reflect various redox state of temporary maximum of Q A Q B 2−
