摘　　要：初夏晴天茶树光合作用日进程测试表明,茶树净光合速率日进程曲线为双峰型,有明显的光合“午 休”现象。光响应及 CO2响应测试进一步证明,强光下光抑制的发生是引起茶树光合“午休”的重要原因。Determination of diurnal photosynthetic variation in Camellia sinensis leaves in summer showed twin-peaked curve with an obvious midday-depress of photosynthesis. Test on response of photosynthesis to light and to CO2 indicated that photoinhibition caused by strong light was the major causes of midday-depress.
