Two barley (Hordeum vulgare L.) genotypes, the cv Aramir and line R 567, were subiected to water deficit by immersing their root systems in polyethylene solutions of potential -1.0 MPa. The stress caused a decline in the leaf-relative-water content (RWC) and affected membrane damage in both the genotypes. A higher decline in RWC and a higher membrane injury index was observed in R 567 in comparison to "Aramir". Water deficit induced an increase in the activity of guaiacol peroxidase (GPO) and catalase (CAT)
