Drought is a major stress that dramatically limits plant growth and productivity. Polyethylene glycol (PEG) has been used for osmotically induced water stress studies in plants. The present work was designed to examine the biochemical response in six barley varieties (three tolerant and three sensitive) at different osmotic potential of Polyethylene glycol-6000 (PEG-6000). The results showed at-3.0 bars osmotic potential of PEG-6000 decreased total chlorophyll and an increase in electrolyte leakage and catalase activity was observed in barley leaves.
