Abstract: The effects of simulated acid rain on camellia (Camellia japonica) leaf membrane damage and antioxidant enzyme activity, chlorophyll content and gas exchange parameters were studied by pot experiments. The results showed that measured factors displayed different change trends in different acid rain stresses. The permeability of plasma membrane and MDA content in camellia leaf gradually increased, and both showed significantly positive correlation; SOD, CAT and POD showed a singlepeak curve which rose first and then dropped. The maximum of SOD appeared in pH 3.0 CAT and POD in the pH 4.0. Chl did not show significantly change among the treatments. Pn, Ci, Gs and Tr showed a trend that rose first and then decreased. Ls showed up after the first fall. Based on the above results, camellia was strong resistance to acid rain, therefore, camellia could be considered as one of the landscaping and vegetation constructing plants on the acid rainhit area.
