Copper-based materials mitigate salinity stress in hydroponically grown lettuce (<i>Lactuca sativa</i> L.).

ABSTRACT: As water scarcity persists, alternative irrigation methods, such as water reuse in agriculture, will be adopted, though often limited by high salinity levels. Hence, the potential of copper to mitigate salinity stress in lettuce (Lactuca sativa L.) was evaluated. Plants were grown hydroponically and exposed to moderate (100 mM) or elevated (150 mM) salinity (as NaCl), either alone or in combination with foliar applied copper-based materials, including copper oxide nanoparticles (nCuO), bulk copper oxide (bCuO), copper sulfide nanoparticles (nCuS), or copper sulfate (CuSO₄). Under moderate salinity, the Cu-based materials were applied at 25 and 100 mg L^-1, while for high salinity, only the 25 mg L^-1 Cu treatment was used. Foliar application of 25 mg L
