Abstract:
Taking the leaves of Volia tricolor seedings as test materials，under the stress of different NaCl stress concentration(0,50,100,150,200,250 mmol/L)，the effect of SOD activity and POD activity and chlorophyll content of the leaves were studied.The results showed that with the increasing of NaCl concentration，SOD activity and POD activity present first decreased then increased and last decreased,and the SOD activity reached the maxine(105.41 U/g FW) at the NaCl concentration(100 mmol/L)，POD activity reached the maxine(624.00 U/g FW) at the NaCl concentration(150 mmol/L)；Chl a,Chl b,Chl and Car showed first increased then decreased，at the NaCl concentration(100 mmol/L),the chlorophyll content reached the maxine(1 929.99 mg/g FW).Under the NaCl concentration of 250 mmol/L，the whole-plant shrinked severely，so that the concentration was lethal concentration.
