The production and quality of citrus fruits can be influenced by several factors, such as the salinity of the water used in irrigation and the type of rootstock. The aim of this study was to evaluate the physical and physicochemical characteristics of 'Tahiti' lime tree fruits grafted on different rootstocks and under salinity in the irrigation water. The experimental design used was the split-plot scheme, with the plots being thirteen rootstocks and the subplot being three levels of salinity, repeated in four blocks, where each plot consisted of a plant. The variables analyzed were average fruit weight, number of fruits per plant, juice yield, skin thickness, pH, titratable acidity, soluble solids and electrical conductivity. Genotypes tangerineira ‘Sunki Tropical’ and TSKC x CTTR – 012 had the highest averages within the salinity of 0.14 dS m-1, with 95 and 84 fruits per plant, respectively. Observing the salinity within each genotype, the lemon tree 'Rangpur Santa Cruz', Citrandarin San Diego, TSKC x TRBK - 007 and TSKC x CTTR - 012 had the highest means for fruit weight, with 47.98, 57.76, 53 .21 and 50.64g respectively. For juice yield, peel thickness, pH, titratable acidity, electrical conductivity and soluble solids there was no influence of the rootstock. Thus, the rootstock and the salinity in the irrigation water interfered in the number and average weight of fruits of the acid lime tree “Tahiti’. The physicochemical quality of the fruits was not influenced by the rootstock genotype and the salinity of the irrigation water interfered with the juice yield, titratable acidity and electrical conductivity.
