Abstract The quantitative content and distribution in organs and tissue compartments of Na+ ions in halophytes Suaeda prostrata Pall., Salicornia perennans Willd., Artemisia santonica L. growing in the areas with chloride-sulfate type of salinization of soil in the vicinity of the Sasyk salt lake (Northwest Crimea) has been determined. It was found that for S. perennans and S. prostrata euhalophytes the strategy of translocation of Nat ions to the organs of the aerial part with increasing NaCl concentration in the medium was typical. In this case, the content of Nat ions in the cell sap of the above-ground parts of plants significantly increases which is more pronounced in S. perennans. Increasing concentrations of NaCl in the medium contribute to 0.50-0.75% improvement in plant growth indicators and protein content increase in vegetative organs. A positive correlation between the content of Nat and biomass accumulation in organs of euhalophytes is shown. Glycohalophyte A. santonica is characterized by localization of Nat ions predominantly in the root tissues. The highest content of Nat ions in the above-ground organs of euhalophytes growing in natural conditions was observed in the phase of active vegetative growth and budding, therefore, it is recommended to mow their aerial organs at these stages of ontogenesis for the purpose of soil desalinization. It is concluded that absorption of Na+, as a strategy of adaptation of halophytes to salinity, not only helps to reduce water potential in cells and plants in general, but also activates anabolism, which directly correlates with their salt tolerance.
