Effects of simulated acid rain with various pH values on leaf in different stages of litchi( Litchi chinensis Sonn.) were studied. The results were as follows: the resistance of growing leaf to acid was the strongest; the leakage amount of soluble sugar, K +, Ca 2+ and Mg 2+ of litchi increased with the decline of the pH value of simulated acid rain, and the cell membrane permeability increased. The leakage amount of K + could be regarded as an important index for evaluating the injury of acid rain to litchi leaf.
