To investigate the alterations of ultrastructure of leaves by acid rain, 10mm of SAR(Simulated Acid Rain, pH 2.0, 2.5, 2.7, 3.0, 6.0) were applied to 4 crops(rice, soybean, barley, and radish) at the two day interval.

To investigate the alterations of ultrastructure of leaves by acid rain, 10mm of SAR(Simulated Acid Rain, pH 2.0, 2.5, 2.7, 3.0, 6.0) were applied to 4 crops(rice, soybean, barley, and radish) at the two day interval. The symptoms of leaf damage by SAR were observed by naked eyes and SEM(Scanning Electron Microscope). The results are summarized as follow: Visible leaf injury were more serious in dicots than monocots such as rice and barley with the order of bean, radish, rice, barley. With the SAR treatment of pH 2.0, histological perturbation of trichome were developed in bean and radish. And with the SAR treatment of pH 2.5, stomata of all tested crops except rice were deshaped.
