Chlorophyll (Chl) fluorescence maximum and effective quantum yield of PSII (Fv/Fm or ΔF/Fm', in dark-adapted or light conditions, respectively) and non-photochemical quenching (NPQ) of Chl fluorescence as a response to different light conditions in (a, c) Codium tomentosum thallus samples and immobilized Elysia viridis individuals and in (b, d) Vaucheria litorea filaments and immobilized E. chlorotica individuals.
Values represent average ± standard error (n = 5). Grey bar: 20 μmol photons m−2 s−1 (low light); White bar: 920 (C. tomentosum and E. viridis) or 1800 (V. litorea and E. chlorotica) μmol photons m−2 s−1 (high-light exposure, HL); Dark bar: dark. Samples were dark-adapted for 60 min before the start of Chl fluorescence measurements. No significant differences (P > 0.05) were found between measurement made on C. tomentosum and E. viridis at each time point. Significant differences (P < 0.05) were found between V. litorea and E. chlorotica during HL and dark-recovery periods.
