The experiment was conducted to find the changes of early growth and chemical components such as chlorophyll content, superoxide dismutase(SOD) activity, free proline content on the different manganese chloride concentration(2,500, 3,500 and 4,500ppm) in rice seedling. Root growth was decreased in highest concentration, 4,500 ppm of Mn compared with the control and germination rate was also decreased 43% at 4,500 ppm of Mn. Chlorophyll content was decreased at Mn 4,500ppm with 1.16mg. Free proline content at 3 day after germination in Mn 4,500ppm was highest relative to the other manganese chloride concentrations. SOD activity was gradually increased as manganese chloride concentration was increased. As a result, it was suggested that an increment of free proline and SOD activity results from the higher manganese chloride concentration.
