Abstract

Ozonated water (OW) effects at low concentration on plant growth of komatsuna (Brassica rapa L. var. perviridis) were investigated in growth chambers under ambient or low temperature. Although there was no difference in plant growth between OW and tap water treatments under ambient temperature, plant growth was promoted by OW treatment under low temperature. Nitrate content per plant was similar between the treatments. Soluble sugar and L-ascorbic acid (L-AA) contents were higher in OW treatment. Thus, promotion of plant growth by OW treatment under low temperature could be related to antioxidant ability due to increased L-AA.
