Three cultivars of wheat (Triticum aestivum; Pak 81, Punjab 85 and Kohinoor) were subjected to mild water stress (-10 bars on-leaf-water potential basis) at tillering, jointing, boot and anthesis growth stages. Water potential of the central leaves was determined on alternate days using a pressure bomb until the desired level of -10 bars was achieved. At this stage water stress was terminated by applying 7.5 cm/ha water by calibrated buckets.
