Abstract Rice seeds after water absorption were directly irradiated with cold plasma. Irradiation of seeds for 5 and 10 s, or of brown rice for 2 s was effective and promoted coleoptile growth, as well as an increase in the levels of phytohormones, including cytokinin and auxin. The growth-promotion responses were also observed at the seedling and mature stages.

Abstract Wood is formed as plants expand in thickness through radial growth, which initiates after apical growth. At the onset of radial growth, dormant procambial cells in the vasculature become active and act as bifacial cambium stem cells, which produce xylem (wood) inward and phloem outward. Cytokinin has been implicated in radial growth initiation; however, its precise mechanisms, especially at the cellular level, remain unclear.
