The influence of Benzylaminopurine (BAP) on grain growth parameters of wheat (Triticum aestivum L.) genotypes (PBW 343 and PBW 527) under water deficit conditions was studied. Wheat crop needs water for the entire period of growth, but some stages are more vulnerable to water shortage and moisture, stress imposed during this period may result in significant yield losses. Water stress imposed at the tillering stage resulted in more yield loss when compared to the stress given at the boot leaf stage. Water stress had decreased the harvest index, but the decrease was more pronounced when the stress was given at the tillering stage when compared to the boot leaf stage. Foliar application of BAP at 100 µg ml-1 given at the vegetative stage under water deficit conditions had showed the stress ameliorative effect.
