A glass house pot experiment was conducted to assess ionic (Na+, K+ and Cl-) relations and contents
in two differently adapted (salt marsh (SM) and inland (IL)) clones of Agrostis stolonifera. In non-saline
medium the roots, stems and leaves of the SM and IL clones demonstrated relatively lower concentration of
Na+ and Cl- as compared to concentration of K+. But when cultured with NaCl, the concentration of Na+ and Cl- increased
in all organs in both the clones. Increased NaCl concentration in culture medium caused a progressive
decrease of K+ uptake in the roots and stems of both the clones. It was also found that Na+ and Cl- concentrations
were higher in stems than in roots and leaves in salt treated plants. In the leaves, however, Na+ and Cl- levels showed a stiochiometric relationship. In older leaves higher concentration of Na+ and Cl- was
found as compared to younger leaves in SM and IL plants. B etter adaptability of SM plants to salt stress was
due to some inherent genetic variability linked with their growth.
Key words: Agrostis stolonifera, genetic variability , inland clone, NaCl, Salt Marsh Clone, stiochiometric relationship,
