The experiment was conducted in DFT hydroponic system, in a completely randomized design with a 5×4 factorial scheme and five nutrient solution concentrations (50, 75, 100, 125 and 150%), four evaluation periods with three replications of three plants for each treatment. Plant height, root length, number of leaves, flowers and floral buttons; fresh and dry weight of shoot and root were determined. The results were submitted to variance analysis, Tukey's test for evaluation periods and regression analysis for nutrient solution. A decrease in the development of the shoot and root was observed with an increase of the number of cultivation days; the greatest number of floral buttons occurred in the third week of cultivation. A reduction in the plant height, root system length, the number of leaves and the fresh and dry weight of shoot was observed generally with the increase of nutrient solution concentration.367-375porNutrient solutionSaline concentrationViola x wittrokiana GamsCultivationPlants (botany)Regression analysisSalinity measurementgrowth responseheighthydroponicsnutrient use efficiencyplantroot-shoot ratioViola wittrockianaViolaceaeArtigoAcesso aberto2-s2.0-337509091722-s2.0-33750909172.pdf
