Analysis of qualitative contribution of assimilatory and non-assimilatory de-excitation processes to adaptation pf photosynthetic apparatus of barley plants to high irradiance
Original language description
The adaptation of barley (Hordeum vulgare L. cv. Akcent) plants to low (LI, 50 umol m -2 s-1) and high (HI, 1000 umol m-2 s-1) growth irradiances was studied using the simultaneous measurements of the photosynthetic oxygen evolution and chlorophyll a (Chl a) fluorescence at room temperature. If measured under ambient CO2 concentration, neither increase of the oxygen evolution rate (P) nor enhancement of non-radiative dissipation of the absorbed excitation energy within photosystem 2 (PS2) (determined asnon-photochemical quenching of Chl a fluorescence, NPQ) were observed for HI plants compared with LI plants. Nevertheless, the HI plants exhibited a significantly higher proportion of QA in oxidised state (estimated from photochemical quenching of Chl afluorescence, qp), by 49-102% at irradiances above 200 umol m-2 s-1...
