The purpose of the present investigation was to study the effects of Ca²⁺ on water relation of two wheat cultivars (Akbar and Kanchan) under salt stress. The two wheat cultivars were grown in pots with 0 and 150 mM NaCl salinity. Calcium was applied in the form of gypsum in 0.12, 0.24 and 0.36g pot^-1 (that is 20, 40 and 60 kg ha^-1) respectively. Salinity decreased RWC, WRC, exudation rate and ψ_leaf, while increased WSD and WUC. Application of increased levels of Ca improved the plant water status in both cultivars. The results obtained in the present study suggest that elevated Ca²⁺ increases salt tolerance by improving the plant water status.
