Water vapor adsorption isotherms were used for the estimation of surface areas and adsorption energy distribution functions of roots of barley grown at different pH levels and at a toxic Al level (10 mg·dm−3), induced at tillering and shooting stages of plants growth. Values of surface area as well as energy distributions were the same for the roots grown at all pH values studied: 2, 4 and 7 and not dependent on the age of the plants indicating that the protons do not alter the physicochemical build-up of the surface of roots. However, significant changes of the root surface properties under the influence of aluminum: increase of surface area, average adsorption energy and amount of highly energetic adsorption sites together with a decrease of low energetic sites were observed.
