Recovery of maximal photochemical efficiency of PSII after photoinhibition. A, Maximal photochemical efficiency of PSII (Fv/Fm) of detached leaves during recovery period at irradiance of 150 μmol quanta m−2 s−1, 30°C. The Fv/Fm was measured by following the photoinhibition treatment to 50% of the initial Fv/Fm values. B, The rate of PSII photodamage at irradiance of 150 μmol photons m−2 s−1, 30°C, in the presence (white symbols) or absence (black symbols) of 200 μg mL−1 chloramphenicol. Wild-type, Diamonds; ppl1 mutant, triangles. Values were means ± sd (n = 3).
