Cuper nanoparticles (CuNps) are nanometer-sized structures, which improve absorption efficiency and rapid availability in plant tissues. Plants’ foliar application of CuNps also minimizes metal accumulation in the soil. The objectives of the present work were: 1) synthetized and characterized CuNps, 2) determine a salt-tolerance sunflower ranking and, 3) quantify the optimal dose of Nps that improves growth parameters in sunflower under salinity.
