Biofortified Rocket (Eruca sativa) with Selenium by Using the Nutrient Film Technique

Selenium (Se) is an essential micronutrient for humans, but most foods are Se deficient, mainly because of its low content in the soil. A Se-deficient diet results increased susceptibility to cardiovascular disease, cancer, and hyperthyroidism. Agronomic biofortification a good alternative increase food. This study investigated effect on growth, yield, rocket. Plants were grown hydroponic system. Seven concentrations (0, 10, 20, 30, 40, 50, 60 µM) evaluated using sodium selenate. Growth, lipid peroxidation, hydrogen peroxide content, enzymatic activity catalase ascorbate peroxidase influenced by concentration. Considering parameters, 10–30 µM promoted best results, with 20 µM, higher yield. Rocket plants treated nutrient solution biofortified, showing contents 598.96 1437.56 mg kg−1 dry mass, than cultivated without Se, which presented 167.84 Se. beneficial rocket plants, while above 50 toxic plants.
