| Abstract: | This paper using the summer maize hybrids ’Zhengdan958’ and ’Nongda108’ as the experimental materials,the effects of different concentrations of MnSO4 on the seed germination of aging maize and some physiological characteristics including the activities of antioxidase and dehydrogenase,and the content of malondialdehyde(MDA),soluble sugar and soluble protein were analyzed.The results showed that the vigor of the seeds and the activity of dehydrogenase appeared to be increased,but actually declined the contents of malondialdehyde(MDA),and the positive effect of 1.0 g/L MnSO4 was the best.The 1.0 g/L MnSO4 significantly enhanced the activity of peroxidase(POD) and catalase(CAT).The 1.0 g/L MnSO4 also significantly increased the activity of dismutase(SOD) and the content of soluble sugar and soluble protein of ’Zhengdan958’,but had less effect on ’Nongda108’.The results suggested that the MnSO4 treatment accelerated seed germination and enhanced antioxidation level.However the effect and mechanism of manganese varied with maize hybrids. |
