| Outline of Final Research Achievements |
Pulse electric field and discharge plasma by pulsed power are used to improve yielding and freshness of agricultural products through promotion of seed germination, growth enhancement and enzyme activity control. For pre-harvest phase, the seed germination and plant growth are promoted by the plasma irradiation through the epigenetics process including gene expressions related to the germination and the growth. The plant growth is also enhanced through the inactivation of pathologic bacteria such as Ralstonia solanacearum and the decomposition of allelopathy chemicals with the pulsed power discharges. For post-harvest phase, the freshness keeping period is enlarged by decomposition of plant hormone such as ethylene in the exportation container. The pulse electric field is also effective for protein conformational change. The enzyme activity such as alfa-amylase is changed through the protein conformational change.
