THE EFFECT OF ULTRAVIOLET-B STRESS ON PHOTOSYSTEM II EFFICIENCY IN BARLEY PLANT
This study was conducted to investigate the effect of UV-B radiation with different exposure times (0, 1, 3 and 5 hours) on photosystem II (PSII) efficiency of barley (Hordeum vulgare L., Bülbül 89) leaves. The polyphasic rise (OJIP) in the chlorophyll a fluorescence was used to evaluate the effect...
