Abstract
The object of this study is to clarify the responses of wintering plants that were re-grown under light / dark condition after treatment of simulated acid snow (SAS) stress with sulfuric acid solution. Fresh weight and relative water content of mature leaves were markedly decreased compared with those of younger leaves during a re-growth period of wheat pretreated by SAS (pH 2.0). Photochemical efficiency of mature leaves was decreased during a re-growth period over 24 hours, but recovered in younger leaves. The level of lipid peroxidation in mature leaves was higher than that of younger leaves during a re-growth period within 24 hours.
