Role of mineral ions in salt tolerance of two wheat (Triticum aestivum L.)cultivars

Effects of NaCl salinity at different growth and developmental stages on io ns accumulation in two wheat cultivars were studied in greenhouse condition s. Concentrations of Na+ in leaves and roots of Ghods, a salt-sensitive cul tivar, were more than that of Boolani, a salt-resistant cultivar. K+ and Ca 2+ contents were found to be less under NaCl treatments. This loss increase d with increasing salinity and was markedly higher in Ghods than in Boolani . There were significant differences between the cultivars with respect to ion absorption and translocation indicating that the cultivars may give gen otype dependent responses under salinity stress conditions.
