Description
Seedling growth and ionic composition of different wheat genotypes was assessed in solution culture at different concentrations of brackish water to determine the tolerance of genotypes. Growth was recorded as shoot fresh/dry weight, root fresh/dry weight, root/shoot length and leaf analysis for major inorganic ions (Na+ ,K/sup k/ and Cl/sup -/). Results showed a reduction in growth parameters was observed in all treatments but it was greatest in T/sub 5/ which contain combination of highest EC, SAR and RSC. The concentration of sodium and chloride ions in leaf sap increased while that potassium decreased by application of brackish water as compared to fit water. Among genotypes SARC-1 and 8670 restricted the uptake of Na+ and preferred K+ uptake and thus maintained high K+ Na+ ratio and performed better in all types of brackish water. (author)
