Shoot water potential (A) and leaf sap osmotic potential (B) of chickpea (Rupali) subjected to control or 30mM NaCl treatments either without infusion or with stem-infusion with water or 0.44M sucrose (Ψπ=–1.1MPa). Plants were grown in nutrient solution culture and NaCl treatments were imposed on 20-day-old plants for 97 d (20/15±2 °C day/night air temperatures). Infusion treatments were started at the time of flowering (42-day-old plants) and continued until maturity. The measurements were taken after 28 d of infusion. Leaf sap osmotic potential was measured on the second youngest fully-expanded leaf (petiole+leaflets). Values are means±SE (n=4). Two-way ANOVA was used to compare salt (S), infusion (I) and salt × infusion interaction (S × I) effects (***, significant with P<0.001; **, significant with P<0.01; *, significant with P<0.05; and n.s., not significant with P>0.05).
