| Outline of Final Research Achievements |
The aim of this study is to investigate the effect of plasma irradiation on the plant growth process. An Arabidopsis was selected as a target plant. The LF plasma jet was used as a plasma source. The growth enhancement of Arabidopsis was observed for the samples of plasma irradiation onto the seeds after vernalization treatment. On the other hand, after the germination the blast of the leaf was observed for the samples irradiated by the plasma onto the leaves. From the chlorophyll fluorescence diagnostic, the maximum photochemical quantum yield of photosystem II was decreased for the leaves treated by the plasma. Moreover, the elemental analyses of the leaves implied that inorganic salt was detected from the surface of the leaf treated by the plasma, resulting in the occurrence of necrosis.
