Title: Effect of potassium on tobacco photosynthesis and transpiration efficiency under soil drought stress and different potassium supplied
Abstract: The experiment of the effect of different potassium supplied on tobacco photosynthesis rate,intercelluar CO 2 content,stomatal conductance,transpiration rate,transpiration efficiency,and biomass under soil drought was carried out in pots.The results showed:The decrease of mesphylls photosynthetic action was reduced by appropriate potassium supplied,and non stomatal inhibition of photosynthesis was also reduced.The adjustive capability of stomatal and transpiration efficiency were improved by appropriate potassium supplied,and got higher biomass.
