Significance of Na+ and K+ for Sustained Hydration of Organ Tissues in Ecologically Distinct Halophytes of the Family Chenopodiaceae

Significance of Na+ and K+ for Sustained Hydration of Organ Tissues in Ecologically Distinct... The contents of Na+, K+, water, and dry matter were measured in leaves and roots of euhalophytes Salicornia europaea L. and Climacoptera lanata (Pall.) Botsch featuring succulent and xeromorphic cell structures, respectively, as well as in saltbush Atriplex micrantha C.A. Mey, a halophyte having bladder-like salt glands on their leaves. All three species were able to accumulate Na+ in their tissues. The Na+ content in organs increased with elevation of NaCl concentration in the substrate, the concentrations of Na+ being higher in leaves than in roots. When these halophytes were grown on a NaCl-free substrate, a trend toward K+ accumulation was observed and was better pronounced in leaves than in roots. Particularly high K+ concentrations were accumulated in Salicornia leaves. There were no principal differences in the partitioning of Na+ and K+ between organs of three halophyte species representing different ecological groups. At all substrate concentrations of NaCl, the total content of Na+ and K+ in leaves was higher than in roots. This distribution pattern persisted in Atriplex possessing salt glands, as well as in euhalophytes Salicornia and Climacoptera. The physiological significance of such universal pattern of ion accumulation and distribution among organs in halophytes is related to the necessity of water absorption by roots, its transport to shoots, and maintenance of sufficient cell water content in all organs under high soil salinity.
