DEPS and PSII quantum yield in preilluminated wild-type and mutant plants
Leaves were illuminated for 15 min at a light intensity of 1,000 μmol m−2 s−1 followed by a dark incubation for 15 min. The DEPS is expressed as (Zx + 0.5 Ax)/(Vx + Ax + Zx) × 100. Mean values ± sd of three independent experiments are shown. For FV/FM ratios, significant differences in comparison with the wild type are indicated by ** (P < 0.01) or * (P < 0.05).
