Plants salt tolerance is a complex phenomena which includes the accumulation of ions in different plant parts. It is, therefore, important that strategies must be adaptabed so that some economic returns may be obtained by growing crop plants in low to moderately salt stressed areas. In this respect the use of thiourea is of greater importance to enable the plants to tolerate salinity. The data reported here suggested that among the thiourea 10.0muM conce. was more important to be used for inducing salt tolerance in barley. Salinity has detrimental decreasing affect on different parameters such as plant fresh eight, dry weight, morphological parameters whereas application of different levels of thiourea tends to alleviate the damaging affect of salinity. The enhanced salt tolerance was noted in terms of greater growth and photosynthetic capacity of leaves followed by increased K+ content and reduced Na+ content of both shoot and root. These findings are important for growing
