Badano wpływ zwiększonego promieniowania UV-B (16 kJ/m2 w ciągu doby) na poziom barwników chloroplastowych, intensywność fotosyntezy i wzrost siewek ogórka odmiany mieszańcowej ‘Polan’ F1 w dwu stadiach rozwojowych. W liścieniach pod wpływem zwiększonej radiacji poziom barwników chloroplastowych i intensywność fotosyntezy wzrastały w porównaniu z kontrolą. W liściach siewek 3-tygodniowych w warunkach stresowych stwierdzono sukcesywny spadek zawartości barwników, intensywności fotosyntezy oraz ograniczenie wzrostu.
EN
The effect of increased UV-B radiation (16 kJ/m2 per day) on the level of chloroplast pigments and rate of photosynthesis and growth of seedlings of cucumber in two stages was examined. In the cotyledons subjected to UV-B radiation content of chloroplast pigments and photosynthesis rate was higher than in controls. In the leaves of 3-week-old seedlings increased UV-B radiation limited chloroplast pigments level, intensity photosynthesis and growth.
