Effect of MX on the lag of O2 evolution

Conditions and procedures as in Figure 1.Chlorophyll was 150 μg mL−1 and MX was 20 μm. Data of five experiments with sd. Cellular ATP, normalized to the control in each experiment, was 0.71 ± 0.15 in the MX-treated, illuminated samples (average ± se of five experiments), and 0.70 ± 5 in the dark-treated samples. The ATP content was not affected by MX at high light intensity.
