%X Applying calcium oxide into soil could improve the ability of rice seedlings in low temperature-and damping-off disease resistance.After treated with calcium,the active oxygen eliminating enzyme activities of rice seedlings increased significantly.Compared with control,the SOD activity in seedling's root and shoot increased.The POD activity in rice seedling's root also increased,but decreased in shoot.The CAT activities decreased at the early stage,but increased at late stage.The soluble protein content in seedling's root and shoot was higher than that of the control.In the PAGE pattern of isoperoxidase,the band number of shoot increased,but that of root decreased.All these changes were part of reasons that applying calcium oxide into soil improved the resistance of rice seedlings to cold and damping-off disease.
