To evaluate the effect of copper nanoparticles on the characteristics of mallow under drought stress conditions, a factorial experiment was conducted in a completely randomized design with three replications under greenhouse conditions in 2017. The first factor of drought stress included three levels without stress and 75 and 50% of field capacity and the second factor was copper nanoparticles at four levels of 0, 10, 50, and 100 mg/lit. The results showed that there was a significant difference between the levels of drought and copper nanoparticles for all of the traits. Also, the interaction effect of drought stress and nano-particle was significant on carotenoid, catalase, biomass, plant yield, as well as 1000-grain weight. The results showed that this plant did respond to drought stress. Among the different levels of copper nanoparticles, the concentration of 50 mg/lit had the highest rate. At a concentration of 50 mg/lit nanoparticles of copper, carbon dioxide, biomass, catalase, 1000-grain weight, and grain yield showed the highest levels of stress-free surface, but at the dry stress level, these properties decreased less due to nanoparticle concentrations. The results also showed that 100 mg/lit level had the lowest levels in the studied traits and harmed the plant by toxicity. Therefore, it can reduce the negative effect of drought stress using copper nanoparticles with a concentration of 50 mg/lit.
