Diurnal characterization of (A) light incident on the upper leaf surface, (B) level of energy dissipation via a regulated non-photochemical route (quantified from chlorophyll fluorescence as Stern–Volmer quenching), and (C) percent of the xanthophyll cycle pool present as zeaxanthin + antheraxanthin (Z + A) in leaves of Alocasia brisbanensis in the understory of a subtropical rainforest (Dorrigo National Park, New South Wales, Australia). V = violaxanthin. Data are from Logan et al. [68].
