Effects of different salt concentrations (0, 50, 75 and 100 mM NaCl) on morphological and physiological responses of Satsuma 30/I and Satsuma 11/1 I clones selected from Turkey due to their superior properties were investigated. The experiment was carried out on 7-month-old plants grafted onto sour orange and Carrizo citrange. Plants were grown with modified Hoagland solution in quartz medium in a climate-controlled greenhouse. Number of leaves, plant height, plant fresh weight, plant dry weight, stem diameter, scale, leaf chlorophyll concentration, photosynthesis rate, transpiration rate, water use efficiency, leaf osmotic potential, plant nutrient elements and leaf-root Na and Cl concentrations were determined. As the severity of salt stress increased in Satsuma 11/1 I, Satsuma 30/I, Satsuma control genotypes, the number of leaves, plant height, plant stem diameter, plant fresh and dry weights were decreased. It was determined that the rate of photosynthesis decreased due to salt stress. Transpiration rate was found to be high in control plants and reduced with the increase of salt stress. In terms of salt symptom scale observation, which is based on the principle of yellowing of the leaf tips of salt stress and the occurrence of blight symptoms in case of salt stress, yellowing and blight of the leaves occurred in the plants treated with a dose of 100 mM NaCl and defoliation was observed. Leaf and root Cl accumulations increased in parallel with the increase in salt stress. As a result of the selection study conducted in Turkey, it was determined that Satsuma 11/1 I and Satsuma 30/I, which are the promising genotypes in terms of fruit yield and quality, lag behind the control plant under salinity stress.
