Abstract: Impact of simulated acid rain with various pH values (4.5 , 3.5 , 3.0 , 2.5) on leaf of papaya ( Carica papaya L. ) seedlings were studied. The results showed that permeability , MDA content ,LOX activity , leakage amount of K+ , Ca2+ and Mg2+ , and saturated fatty acid percentage in leaf increased with the decline of the pH value of simulated acid rain , unsaturated fatty acid percentage and IUFA decreased with the decline of the pH value of simulated acid rain. The injury threshold value of leaf to simulated acid rain was ≤3.0 by the standard of the result using significance tested with L1S1D. at 0.05 level.

Key words: Papaya, Simulated acid rain, Permeability, LOX activity, Fatty acid composition
