Gradual disassembly of photosystem 2 in vivo induced by excess irradiance. A hypothesis based on changes in 77 K fluorescence spectra of chlorophyll a in barley leaves.
Original language description
Effects of short-term exposure to different irradiances on the function of photosystem 2 (PS2) were studied for barley grown at low (LI; 50 mol m-2 s-1) and high (HI; 1100 mol m-2 s-1) irradiances. HI barley revealed higher ability to down-regulate the light-harvesting within PS2 after exposure to high irradiance as compared to LI plants. This ability was estimated from the light-induced decreases of F685/F742 and E476/E436 in emission and excitation spectra of 77K chlorophyll (Chl) a fluorescence in vivo which was 65 and 10% for HI plants as compared to 30 and 2% for LI plants, respectively.
