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。

摘  要:
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 PSⅡ(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.
