Abstract: To understand the inhibition mechanism of alginate to tobacco mosaic virus (TMV), the in vitro inactivation and systemic resistance induction were investigated in tobacco treated with alginate. The results showed that, after spraying alginate, the lesion inhibition rate reached 66.67%, proliferation inhibition rate reached 34.67%, the expression level of N gene increased to 2.67 times of the control levels, POD activity increased to 3.46 times, SOD activity increased to 1.43 times of the control levels. Therefore, proliferation inhibition of alginate to TMV might be caused via the increase of disease-resistance and oxidation resistance abilities.
