Abstract
This study was intended to verify the effects of H2-enriched electrolyzed water in hydroponic nutrient solutions, as well as its mechanism. In the experiment, a “Reduced Vegetable Water Purifier” H2-enriched electrolyzed water producing system, which was supplied by Nihon Trim Co., Ltd., was used. According to the measurements in which ORP electrodes were used as an indicator of oxidation-reduction power, the H2-enriched electrolyzed water showed superior reduction power, reaching levels as low as −113 mV. The germination and early growth tests performed on the Komatsuna plants revealed that the roots grew significantly longer in the H2-enriched electrolyzed water than in the control. Komatsuna plants were cultivated by the NFT methods in a nutrient solution prepared using H2-enriched electrolyzed water. This study demonstrates that the nutrient solution in which H2-enriched electrolyzed water was used promoted the growth of leaves and roots of Komatsuna plants.
