Abstract:
Using one year old potted seedlings of Magnolia liliiflora as material，the growth and physiological responses to the intimidation of simulated acid rain were measured by testing the concerned biochemistry index of one year old Magnolia liliiflora.The results indicated that pH value of 3.5 was the critical point which Magnolia liliiflora could endure the hurts from acid rain.Under the intimidation of gently acid rain（pH>3.5）,the content of soluble protein the activity of peroxidase and superoxide dismutase of Mchella liliiflora increased with the acidity of the acid rain increased，but the content of soluble protein declined and the activity of peroxidase and superoxide dismutase decreased rapidly with the acidity increased When the pH value under 3.5.The correlation analysis of several indexes showed that the activity of catalase and the content of malondialdehyde were obvious negative correlated.
