Dinitrogen pentoxide (N₂O₅) is promising for various applications owing to its unique high reactivity. But it has rarely reported in applied research due to the difficulty of its synthesis and storage. Recently, we have developed a new technique, which can electrically generate N₂O₅ using atmospheric-pressure plasma from air with high safety and easy handling. In this presentation, we will show the results on the initial Ca²⁺ response induced by N₂O₅ exposure in a plant and the possibility of the plant immunity enhancement toward agricultural applications of plasma-generated N₂O₅.
