Abstract
Effects of NaCI salinity at different growth and developmental stages on ions accumulation in two wheat cultivars were studied in greenhouse conditions. Concentrations of Na + in leaves and roots of Ghods, a salt-sensitive cultivar, were more than that of Boolani, a salt-resistant cultivar. K+ and Ca2+ contents were found to be less under NaCl treatments. This loss increased 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 genotype dependent responses under salinity stress conditions.
