Nonsaline and saline (30 mM NaCl), Zn (10, 20, 40 mg kg -1 ) and without Zn treatment and factorial combinations of NaCl and Zn on the fresh and dry weights of the plants, and sodium (Na), chloride (Cl) and zinc (Zn) contents of both young and old leaves were determined and the effects of Zn on the Na and Cl translocation within the plants were investigated. Salinity decreased the fresh and dry weights of the plants while this effect of salinity diminished with increasing Zn levels. Na and Cl con-centrations of both young and old leaf tissues decreased with increasing levels of Zn treatment and these decreases were more pronounced in the presence of salinity. Zn treatment also decreased Na and Cl translocation from old leaves to young leaves. Zinc con-tent of the leaf tissues increased in both saline and nonsaline conditions with Zn treatment. From the result of the present study, it was concluded that in the salt affected areas, zinc application could alleviate possible Na and Cl injury in plants.
