Abstract: Exposure of Pistacia vera L. plants to natural or imitating midday high irradiance induced lowering of apparent quantum yield (AQY) , Fm (maximal fluorescence) , Fo (minimal initial fluorescence) , Fv (variable fluorescence) , photochemical efficiency of PS Ⅱ (Fv/ Fm) , and photochemical quenching coefficient (qP) , but raising the non-photochemical quenching coefficient (qN) . By high irradiance , both net phtosythetic rate (Pn) and photorespiratory rate (Pr) were decreased , but the ratio of Pr/ Pn was improved.

Key words: Pistachio, Photoinhibition, Chorophyll fluorescence, Photorespiratory
