Abstract (EN): <jats:title>Abstract</jats:title><jats:p>Salinity is one of the major factors limiting plant development and crop productivity. Damage to plants exposed to salinity has been ascribed to ion toxicity, water deficit, nutrient imbalance and oxidative stress. The physiological and biochemical aspects of salt tolerance in plants have attracted considerable interest, but few studies have been carried out to study the ultrastructural changes in plant cells adapted to salinity. These changes may be helpful in elucidating the mechanisms of salt tolerance at cellular level. In plants exposed to salinity, alterations of cell walls and structure of cellular membranes, the swelling of thylakoids and a decrease in the amount of grana stacking in chloroplasts, and the vacuolation of cells have been observed n1, 21.</jats:p>
