ABSTRACT
Salinity stress is one of the major abiotic stresses limiting crop productivity and the geographical distribution of many important plants/crops worldwide. Salt and water stress have been recognized as major agricultural problems, especially in arid and semi-arid regions, for a long time. The effect of salt stress on nutrient element use and nutrition as well as metabolism in plants has been studied for various plants using different methods. The crude protein contents of both shoots and roots of the three green bean cultivars were markedly lower under stress conditions as compared with the controls. For all cultivars, water uptake also was substantially decreased under stress conditions, particularly at the highest level of stress. Among the three cultivars, Tender Improved was the least and Slim Green the most severely affected by salinity in all aspects of stress. Reduction in water uptake by other plants, or other bean cultivars, due to salt stress has been reported by many investigators.
