| The experiments were conducted to examine the effects of sulfur dioxide on catalase activity in germinating seeds under dark conditions and in green plants under light conditions. Three kinds of plants, bean (Glycine max M.), cabbage (Brassica oleracea L. Chungbang No.1) and rice (Oryza sativa L. Suwon No.213-1) were used in this study. Both thegerminating seeds and the leaves were treated with various concentrations of sulfur dioxide for both one green plants with two and twelve hours. In the results of the measurement of catalase activity it was found that plant injuries by sulfur dioxide for the period of photosynthesis were higher than those for the period of respiration. In the control, apparent catalase activity under the light condition of photosynthesis showed a considerable decrease in comparison with catalase activity under the dark condition of respiration. This tendency also appeared markedly in the gas treatment. In the gas treatment for twelve hours, the decrease of catalase activity was higher than that of one hour in both photosynthesis and respiraton. It was thought that sulfur dioxide was an inhibitor of catalase activity in higher concentration of the gas. |
