vs. ΔI for Imean = 1.25, 3.25, 13.75 μmol m−2 s−1.
The averaged values and the standard deviations are shown by points and bars. Fitted lines are drawn by broken lines. The slopes are: 0.302 ± 0.0252 for Imean = 1.25 μmol m−2 s−1, −0.0147 ± 0.0226 for Imean = 3.25 μmol m−2 s−1 and −0.243 ± 0.0217 for Imean = 13.75 μmol m−2 s−1.
