The intensity of photosynthetic oxygen evolving intensity of algae suspension decreased in a similar way to the FL parameter values in proportion to the applied dose of UV-B radiation (0.0, 3.2, 6.4, 12.8 kJ·m-2). The correlation between photosynthetic oxygen evolving intensity and FV/FO ratio was better than that between photosynthetic oxygen evolving intensity and FV/FM. The vitality index (Rfd) in the UV-B irradiated algae strongly decreased, compared to the control, which indicates inhibition of potential CO2 fixation and cooperation between light and dark reactions of photosynthesis. It may indicate damage of Rubisco.}, type={Artykuły / Articles}, title={Photosynthetic Responses of Chlorella vulgaris L. to Short-Term UV-B Radiation Exposure}, URL={http://journals.pan.pl/Content/102665/PDF/ABC%20Bot.%201-18%205-E.Skorska%20i%20in.pdf}, doi={10.24425/118048}, keywords={chlorophyll fluorescence, microalgae, oxygen evolving, photosysthem II, phytoplankton, ultraviolet radiation}, }
