Resumo: | Experiments with three species of the Black sea plankton algae conducted without their preliminary adaptation to flowage conditions in chemostat showed a stimulating action of protein hydrolysate added to the Goldberg medium on the growth of Platymonas viridis (28%) and Ditylum brightwellii (30%). The rate of Prorocentrum micans growth under these conditions, on the contrary, decreased by 8% as compared to the control. Studies in the organic matter influence on the photosynthesis intensity yielded unlike results. The photosynthesis in Prorocentrum micans and Platymonas viridis after a 7-9 day exposure grew by 15-22% on the average and that in Ditylum brightwellii was inhibited by 20%. The regulating action of dissolved organic matter on growth and photosynthesis of the same phytoplankton species in stationary and flowage cultures is shown not always to be alike in the character (sign) of its action and in the magnitude of regulating effect.
