ETR(II) LC of a dilute suspension of Chlorella (300 μg Chl/L) using 440- and 625-nm light derived from the original LC of rel.ETR depicted in Fig. 4 by transformation of the PAR-scale into a PAR(II) scale using Eqs. 3 and 4 (see text). Illumination time at each intensity-setting was 3 min. Sigma(II) values of 4.547 and 1.669 nm2 were applied for 440 and 625 nm, respectively. In the calculation of ETR(II)440 and ETR(II)625, F v/F m values of 0.68 and 0.66 were used, respectively. For comparison of the corresponding LC without PAR transformation, see Fig. 4
