| 摘 要： | 中午或模拟中午强光照射后, 阿月浑子叶片表观量子效率(AQY) 、最大荧光(Fm) 、初始荧光(Fo) 、可变荧光(Fv) 、光化学效率(Fv/ Fm) 、和光化学猝灭系数(qP) 下降, 而非光化学猝灭系数(qN) 升高; 强光处理后, 叶片的净光合速率(Pn) 和光呼吸速率(Pr) 均下降, 但Pr/ Pn 的比值却升高。

| 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. |

| Keywords: | Pistachio Photoinhibition Chorophyll fluorescence Photorespiratory |
