以烤烟品种K326为试验材料，通过液培法研究硫(0.01~16 mmol/L)对旺长期烤烟气体交换及叶绿素荧光参数的影响。结果表明，硫对旺长期烤烟的类胡萝卜素和蒸腾速率(Tr)无显著影响，但4mmol/L硫浓度使烤烟叶绿素含量和净光合速率(Pn)显著升高，0.01、16 mmol/L处理则显著降低。胞间CO2浓度(Ci)随硫浓度增加而降低；气孔导度(Gs)在2~16 mmol/L处理随硫浓度的升高而显著降低。4 mmol/L处理烤烟的光化学有效量子产量(EQY)和光合电子传递速率(ETR)略高于2、8 mmol/L处理，但显著高于0.01、16 mmol/L处理。0.01、16 mmol/L处理的非光化学猝灭(NPQ)相差较小，显著高于2~8 mmol/L处理。0.01 mmol/L处理的水...

Flue-cured tobacco variety K326 as the test material, a hydroponic experiment was carried out to study the effects of different concentrations of sulfur （0.01-16 mmol/L）on chlorophyll content, photosynthesis, and chlorophyll fluorescence parameters of flue-cured tobacco leaves in fast growing period. Concentration of sulfur had no significant influence on carotenoid and transpiration rate （Tr）. The contents of chlorophyll and the net photosynthetic rate（Pn）in 4 mmol/L concentration of sulfur were significantly higher than those in 0.01 an...
