The present study was conducted to evaluate mango (Mangifera indica L.) rootstocks under induced moisture stress condition for various morpho-physiological traits. The result revealed that the rootstock Totapuri recorded minimum plant height (23.55 cm), stem diameter (1.16 cm), leaf area (380.30cm²), stomatal density (78.36 No./mm²), plant biomass (98.00 g) and maximum relative water content (90.26 %). Among the different stress level, lower plant height (23.93 cm), stem diameter (1.27 cm), relative water content (77.49 %), leaf area (463.59cm²), stomatal density (80.97 No./mm²) and plant biomass (97.66 g) was found in severely stressed treatment. However interaction effect showed that Totapuri rootstocks under severe stressed condition recorded minimum plant height (22.65 cm), stem diameter (1.04 cm), leaf area (352.32cm²), stomatal density (70.51 No./mm²), plant biomass (96.31 g) and maximum relative water content (94.25 %).The rootstock Totapuri clearly shows the survivable strategies under severe stressed period by reducing its plant height, stem diameter, leaf area. As by reducing crop canopy there will be reduced water loss through transpiration and evaporation rate. More rapid reduction in stomatal density and ability to maintain higher relative water content under stressed period were the chief physiological adaptations characterized by rootstock Totapuri and Alphonso to tolerate stress condition.
