abstract：:Photoinhibition of Photosystem II (PSII) in lincomycin-treated leaves begins as a first-order reaction, but fluorescence measurements have suggested that after prolonged illumination, the number of active PSII centres stabilizes to 15-20% of control. The stabilization has been interpreted to indicate that photoinhibit...
