Abstract
Three maize cultivars (FFR-915C, JX-77 and G-4578) were grown in the field with water-stressed treatment and control. Leaf water potential, osmotic potential and solute concentration in cell sap were measured on 20th day after the treatment. Degree of leaf rolling was measured on 22nd day after the treatment. Cultivar FFR-915C could maintain high turgor under water stress by lowering the osmotic potential. Sugar and K were the major contributors to the osmotic potential. Degree of leaf rolling was less in cultivar FFR-915C and it could recover from leaf rolling by maintaining high turgor under water deficits. FFR-915C seems to be tolerant to drought than other two cultivars.
