- Abstract:

Based on pot experiments, we studied the effects of acid rain on the physiological and ecological characteristics of different garden plants which were treated with simulated acid rain at pH 1.7, 3.0, 4.3, 5.6 and 6.5 (CK). The results showed that the acid precipitation with different pH values inhibited, to different extents, shoot growth of all the 6 species, and the harm suffered by the plants increased with the acidity of rain, the simulated rain had no inhibition to plants at pH 4.3 and 5.6, and had significant inhibition to plants under pH 3.0. As the acidity of the simulated rain increased, the MDA content and plasmalemma permeability of the leaves increased, when pH was less than 3.0, the MDA contents and plasmalemma permeability of the leaves sharply increased, and when pH was 1.7, the garden plant leaves were badly damaged. While the chlorophyll content, N and P contents had the opposite trend with the MDA content and plasmalemma permeability of the leaves. The result revealed that acid rain enhanced the sensitivity of different garden plants to environment through correlation and regression analysis, the species differed in their susceptibility to acid rain, pH 3.0 to 4.3 could be used as an invisible critical point of acid rain damage to their leaves. Therefore, these different garden plants could be considered as one of the landscaping and vegetation constructing plants in the acid rain-hit areas.
