treatment of detached leaves with constant high light in the presence of methyl viologen (MV) or a soluble alpha-tocopherol analogue, 2,2,5,7,8-pentamethyl-6-chromanol (PMC). MV significantly depresses photochemical quantum yields in PSI and PSII when compared to PMC. Methyl viologen not only strongly downregulates electron flow from PSII to PSI (ETRII), but also intensely inhibits circular electron transport in the shade-establishing species. Activation of circular electron flow cannot prevent PSI photoinhibition in Psychotria henryi. Strong PSII photoinhibition by MV.
