To study the effectofNaClsalinityon theuptakeofmineral elementsindifferent organs ofeggplantthree cultivars including Jahrom landrace, Dezful slim, Indian cottage grown in outdoor conditions, an experiment was performed based ona completely randomized designwith10replications.Ten days old seedlings equal in height and stem diameter in crown area were transformed into plastic pots containing 9 kg local field soil and irrigated with tap water for 20 days. Seven salinitylevelswere used with concentrations of0, 10, 20, 40, 60, 80and100 mMNaCl.Different amountsof NaCl were added to tap waterwith electrical conductivity of219µS.cm-1 and salinity stress followed for five months. The resultsshowed that the salinity caused increasing Na+concentrationin root, shoot, and leaf and Ca2+ in roots.Moreover, thesalinitydecreased the rootpotassium, leaf calcium, and the ratio of K+/Na+ in root, stem and leaf. No significant changes were recorded in the accumulation of potassium in leaf and stem calcium in stem and nitrate in leaf. Among studied cultivars based onmeasuring theaccumulationofexcessions, the Jahromilandrace were evaluated asahighertolerancegenotype in comparison with Dezfulslim cultivar which showingthe highest sensitivity toNaCl salinity.
