ARPA BİTKİSINDE ULTRAVIYOLE-B STRESİNİN FOTOSİSTEM II ETKİNLİĞİ ÜZERİNE ETKİSİ

Bu çalışma, farklı sürelerde [0 (kontrol), 1, 3 ve 5 saat] UV-B ışımasının arpa (Hordeum vulgare L., Bülbül 89) yapraklarının fotosistem II (PSII) etkinliği üzerine etkisini araştırmak için yapılmıştır. UV-B stresinin, PSII etkinliği üzerine etkisini değerlendirmek için klorofil a fluoresansındaki polifazik artış (OJIP) kullanılmıştır. UV-B stresi, arpa bitkisinin JIP-Testine göre hesaplanan fonksiyonel parametrelerini ve yapısal parametrelerini önemli düzeyde etkilemiştir. Farklı sürelerdeki UV-B’nin polifazik klorofil a fluoresansı üzerine etkisi, PSII’nin donör ve akseptör kısmının kısmi öneminin değerlendirilmesi perspektifinden tartışılmıştır

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 effectof UV-B stress on the efficiency of PSII. UV-B stress significantly affected the functional parameters and structural parameters calculated by JIP-Test. The effect of UV-B with different application times on polyphasic chlorophyll a fluorescence parameters are discussed from the perspective of evaluating the relative importance of UV-B of donor and acceptor side capacity in PSII.
