In halophytes with different mechanisms of salt metabolism, growing on solonchaks meadow steppe Zauralye studied the accumulation of Na + and Cl-, sucrose and proline in leaves and underground parts. Major role in the adaptation of halophytes have active salt exchange mechanisms, which appeared in the selective absorption of Cl-and Na + from the soil solution, differential accumulation of Cl-and Na + in the leaves compared with roots, especially in solenakaplivayuschego Salicornia europaea. Artemisia nitrosa different preferential accumulation of Na + compared to Cl-, weak differentiation of the number of ions. All plants except Limonium caspium, characterized by a high content of sucrose in the roots compared to the leaves. In the adaptation of weed species Saussurea amara are important mechanisms for the accumulation and localization of salt ions and osmoprotektornaya role of proline.
