The concentration of Na+, K+, Ca2+ and Mg2+ in the root and aboveground organs of three halophyte species (Salicornia europaea, Suaeda maritima and Salsola soda) as well as in the soil where they grew from maritime and inland saline areas were investigated. The aim of our research was to evaluate the capability of some halophyte species to absorb different cations and to find if there exists differentiation of salt accumulation between populations from inland and maritime saline areas. In five analyzed localities (Tivatska solila, Ulcinj salina, Slano Kopovo, Melenci, Okanj), external Na+ concentrations exceeded other investigated cations. Our investigated halophytes accumulate more Na+ than the Mg2+, Ca2+ and K+ and more cations were recorded in aboveground organs than in the root. Populations from maritime saline area generally had higher cation concentrations than plants from inland saline area.
