摘　　要：茶树喷洒NaHSO3的试验结果表明,2,5mmol/LNaHSO3的水溶液对茶芽生长和光合速率有显著的促进作用。NaHSO3可提高气孔导度,但光合促进作用并非是气孔效应。NaHSO3对PSⅡ的荧光特性、光化学活力和电子传递速率的影响不显著,也不显著影响其对能量的分配。The experimental results of spraying NaHSO_3 of tea trees showed that 2,5 mmol/L NaHSO_3 significantly enhanced bud growth and photosynthetic rate of tea trees. The increase in photosynthetic rate was not due to stomatal effect.NaHSO_3 significantly affected neither the fluorescence characteristics,photochemical activity, and electron transport rate of PSⅡ nor significantly affects the energy distribution.
