Selenium (Se) is an essential micronutrient for mammals, although its availability in plants varies widely due to agricultural methods and environmental conditions. As plants are the primary dietary source of Se, biofortification of aromatic plants is a promising strategy to increase consumer Se intake. Moreover, Se has been shown to play beneficial roles in plants, particularly under abiotic stress conditions. This study aimed to examine the combined effects of Se biofortification (5 μM) and moderate salinity stress (10 mM NaCl) on basil (Ocimum basilicum L.) and peppermint (Mentha × piperita L.) growing in a floating system. The results indicated a higher Se concentration in plants subjected to the Se + NaCl treatment, with approximately 33.01 and 34.87 mg kg−1 in basil and peppermint, respectively. Notably, plants exposed to NaCl and Se accumulated 25 % more Se than those treated with Se alone.
