Changes in the yield of Chl fluorescence in intact cells during incubation with 1.0 m sorbitol. At designated times, a portion of each cell suspension was withdrawn and kept in darkness at 32°C for 15 min; the maximum fluorescence of Chl (Fmax) was then determined at 25°C before and after the addition of 1 mg mL−1 dithionite. ●, No dithionite; ▴, after addition of dithionite. Each point represents the average with se of results from three independent experiments.
