Botanica}, howpublished={online}, year={2011}, publisher={Biological Commission of the Polish Academy of Sciences – Cracow Branch}, abstract={Cucumber (Cucumis sativus L. cv. Dar) leaves exposed to UV-B irradiation at a biologically effective dose of 9.5 kJ m-2d-1 showed decreased chlorophyll fluorescence parameter values versus the control; in peppermint (Mentha piperita L. cv. Asia) leaves those values were almost unchanged after treatment. Fv/Fo and Rfd were reduced more than other values, indicating inhibition of the oxygen-evolving complex and cooperation between the light and dark photosynthesis reactions as the primary targets of UV-B. The photosynthetic electron transport rate showed less change directly after irradiation, but after 24 h of recovery it was reduced to 50% of the control. Generally, photosystem II of peppermint leaves appeared more tolerant to the applied UV-B radiation than in cucumber leaves.}, type={Artykuły / Articles}, title={Comparison of Chlorophyll Fluorescence Parameters of Cucumis Sativus and Mentha Piperita Leaves Exposed to Short-Term UV-B Irradiation}, URL={http://www.journals.pan.pl/Content/81715/PDF/abc53_1_02.pdf}, doi={10.2478/v10182-011-0002-7}, keywords={cucumber, primary photosynthesis reactions, peppermint, ultraviolet-B}, }
