| Outline of Final Research Achievements |
Two functions of the plasma generated reactive species for agricultural applications, the germination suppression of pathogenic conidia and the induction of defense related genes of rice seeds, are experimentally investigated. The germination suppression effect is enhanced by the water molecular fraction increase in plasma, correlating with hydroxy radical density in the plasma effluent and nitrate ion concentration in the conidia suspension. On the other hand, the gene expression degree of the defense related genes of rice seeds are significantly increased under a certain plasma effluent exposure condition and are varied simultaneously with the mixture variation of the reactive species. The difference of the reactive species correlated with the germination suppression and the defense related genes indicates the feasibility to switch those functions by the reactive species control in the plasma effluent.
