Effect on Anti-oxidation of Euonymus Bungeanus under Na_2SO_4 Treatments

Fang fei et al.(1 Agriculture College of Shihezi University,Xinjiang Shihezi 832000)  
The experiment treated seedlings of Euonymus bungeanus with different concentrations of Na2SO4,measured and analyzed the activities changing rules of enzymes such as superoxide dismutase(SOD)、catalase(CAT) activity and peroxidase(POD) in the seedlings.The results showed:(1) SOD-CAT was the main way of defense enzyme system in leaves of Euonymus bungeanus;(2) The largest activity of SOD and POD was obtained with Na2SO4 concentration of 300mmol / L;(3) The largest activity of CAT was obtained with Na2SO4 concentration of 150mmol / L,when Na2SO4 concentration was 300mmol / L,the activity of CAT took the second place.which had a little difference between concentration of 300mmol / L and concentration of 150mmol / L.According to above results:we could treated seedlings of Euonymus bungeanus with Na2SO4 concentration of 300mmol /L,which is a critical concentration,to increase its resistence.This paper aimed for providing scientific basis of choosing special trees in saline-alkali Regions of Xinjiang Group of Production and Construction.
