Abstract

The effect of ozonated water on plant growth was examined. Ozonated water, produced by an atmospheric barrier discharge, was supplied intermittently twice a day, except on rainy and cloudy days, to the underground roots of komatsuna (Brassica rapa var. perviridis) by changing the feeding time interval. Being apart from the feeding position, the weights of komatsuna increased by 2.4 times in the case of 5-sec feeding and 2.9 times in the cases of 78-sec feeding, compared to those of control. Intermittent supply of a suitable amount of ozonated water to the underground roots was found to activate plant growth.
