摘要：
An experiment was conducted to determine the effect of water stress on nutritional changes in tolerant (DS-4 and Chakwal-86) and susceptible (DS-17 and Pavon) genotypes in lysimeters. The stress was imposed at different growth stages (pre-anthesis, post-anthesis, terminal drought). The biomass (dry weight) and Ca, Mg and P concentration decreased with water stress in all the wheat genotypes. However, the tolerant genotypes had less reduction than susceptible at all the treatments. Potassium increased in all wheat genotypes due to water stress and was higher in tolerant than susceptible genotypes. Sodium content was not affected by water stress.
