Salinity is one of the major environment stress factors, which limits the growth and development of plants. Approximately one third of the land being irrigated worldwide is salt affected. All plants are subjected to a different type of stress either abiotic or biotic throughout their life cycle. Growth reduction is considered as a main morphological effect of salinity. Excess of salts altered the adsorption. capacity of water and reduced the growth by effecting osmotic pressure. Salinity checks the water absorption rate of roots, and prevents roots fro performing their osmotic activity. It creates drought like conditions to plants. It seems that perennial plants can toler te salinity better than annual plants. Salinity also altered nutrient balance of plants, they required for healthy growt . Biotechnological approaches are proved successful to develop salt tolerant lines. Cell and tissue culture techniques have been used to obtain salt tolerant plants.
