Plasma utilization and plasma processing, which are employed in the semiconductor industry and other industrial fields, are vacuum processes. In contrast, Atmospheric-Pressure Plasma (APP) enables plasma processing at atmospheric pressure and low temperatures, making it possible to process virtually any material accessible to humans. Consequently, research on plasma processing using APP has rapidly increased in recent years. Its application and utilization fields are expanding beyond materials engineering into agriculture, medicine, and other areas. This study aims to induce biological responses, such as hormone activation as an alternative to pesticides and chemicals, through APP stimulation. We attempted APP stimulation on plant leaves and sought to detect changes and responses in the leaves as alterations in chlorophyll content (SPAD values) and color (RGB values). This presentation details the APP irradiation method for plant leaves and the evaluation method for the irradiated areas.
