Abstract
Cadmium (Cd) is one of the most toxic metals for the physiology of plants. Proper nutrient management through wastewater reuse can be an efficient strategy to mitigate its effects. In this research, the effects of cadmium were evaluated in the hydroponic cultivation of Solanum lycopersicum L. We conducted two experiments: one using mining wastewater with concentrations of 0, 5, 10, and 15 mg L-1 of Cd2+ (Experiment 1) and another using deionized water with concentrations of 0, 2.5, 5, 10, and 15 mg L-1 of Cd2+ (Experiment 2). Cadmium stress in plants reduced leaf area, chlorophyll content, and concentrations of potassium (K) and manganese (Mn), and increased concentrations of sulfur (S), phosphorus (P), iron (Fe), and copper (Cu). The employment of mining wastewater improved the plant’s response to Cd stress by reducing the translocation of Cd and increasing the contents of P, S, calcium (Ca) and magnesium (Mg) in leaves. At the same time, the use of deionized water decreased the contents of Cu in leaves. These nutrition-related effects influenced leaf area and chlorophyll content, as both indicators showed less impairment in the experiment with wastewater. These results provide additional value to the reuse of wastewater in agriculture.
