Abstract:
The effects of different concentrations of NaCl (0,0.10,0.15,0.20 and 0.25 mol/L)on plant growth，photosynthetic characteristics of different Houttuynia cordata Thunb from Emei,Sichuan province (HTE)and Huaihua county ,Hunan province(HTH)were studied.The results showed that with increasing NaCl concentration,the net photosynthetic rate(Pn)，transpiration rate (Tr),stomatal conductance(Cs) and intercellular CO2concentration(Ci)decreased significantly，It was indicated that the growth and photosynthesis of the HTE and the HTH were inhibited under NaCl stress.However，when the concentrations of NaCl increased 0.25 mol/L，the net photosynthetic rate(Pn)，transpiration rate (Tr),stomatal conductance(Cs) and intercellular CO2concentration(Ci) of the HTH increased,the results indicated that the HTH adjusted themselves to improve photosynthesis and adapt to salt stress.
