The article addresses influence of moderate osmotic stress on water status in barley plants (Hordeum vulgare L., cv. Prairie). Water deficit was created by 6% solution of polyethylene glycol (PEG 6000). To identify the possible contribution of aquaporins in the reduction of hydraulic conductivity under the effect of PEG the barley plants were treated with Fenton's reagent. Active water exchange regulation by plants under moderate osmotic stress via aquaporins, osmotic adaptation and changes in the morphology of the root is discussed.
