The study on the photoinhibiton of Pistachio shows: the exposure of Pistacia vera seedlings to high irradiance induced lowering of apparent quantum yield , maximal fluorescence , minimal fluorescence , variable fluorescence , photochemical efficiency of PS Ⅱ, and photochemical quenching , but raising the Non-photochemical quenching , this indicates that high irradiance reduces the quantities of oxidized Q〓, which depresses the ability of electron transport from Q〓 to Q〓, and lowers the electron transport rate and the photosynthesis rate.

对&光抑制&研究表明，强光照射后，叶片表观量子效率、最大荧光、初始荧光、可变荧光、光化学效率、和光化学猝灭系数下降，而qN升高，说明强光处理降低了Q〓的氧化态数量，使Q〓→Q〓传递电子的能力下降，进而导致了电子传递速率和光合速率的下降。
