RESUMO

The light-dependent quenching of the chlorophyll a fluorescence at room temperature by N-methylphenazinium methyl sulfate (PMS) was investigated with isolated chloroplasts inhibited by 3-(3,4-dichlorophenyl)-1,1-dimethylurea. Other investigators have considered this quenching to be a consequence of the formation of a high energy membrane state related to photophosphorylation.
