Abstract
Growth and ion uptake of Hordeum jubatum L. along artificial and natural soil salinity gradients were studied. Elevated salinity levels caused a significant decrease in biomass accumulation under laboratory and field conditions. The upper limit for vigorous growth and reproduction was 1.0% NaCl. Salinity levels significantly affected the uptake and distribution of Cl-, Na+, K+, and Ca++ ions. There was a significant difference with increased salinity in the distribution of Cl-, Na+, K+, Ca++, and Mg++ ions between roots, stems, and leaves. Hordeum jubatum preferentially transported K+ ions over Na+ ions to the shoot against a strong external concentration gradient of Na+ ion
