*F 0: fluorescence at 20 μs after the onset of actinic illumination; F 300: fluorescence value at 300 μs; F J: fluorescence value at the J-step (2 ms) of OJIP; F I: fluorescence value at the I-step (30 ms) of OJIP; F M: fluorescence value at the peak of the OJIP test; Values are given as the means ± SD (n = 5–7).
