Abstract: When 15mg稬-1 LaCl3 was used to spray wintersweet three times ,it reduced the damage effect of simulated acid rain at pH 2.5. It was considered that the effect of LaCl3 on the wintersweet was realted to following factors.(1)Raising photosynthetic rate and chlorophyll content;(2)increasing catalase activity;(3)decreasing malondialdehyde content; (4)reducing cell membrane permeability and (5)keeping stability of pH value of cell juice.
