<p>The purpose of the present investigation was to study the effects of Ca<sup>2+</sup> 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<sup>-1</sup> (that is 20, 40 and 60 kg ha<sup>-1</sup>) respectively. Salinity decreased RWC, WRC, exudation rate and ψ<sub>leaf</sub>, 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 Ca<sup>2+</sup> increases salt tolerance by improving the plant water status.</p> <p>International Journal of Environment, Volume-2, Issue-1, Sep-Nov 2013, Pages 1-8 <strong><em></em></strong></p> <p>DOI: <a href="http://dx.doi.org/10.3126/ije.v2i1.9202">http://dx.doi.org/10.3126/ije.v2i1.9202</a></p>
