Abstract

In order to investigate the effect of water deficit tension and titanium dioxide nanoparticle spraying on maize yield and activity of some sweet corn antioxidant enzymes, the present experiment was conducted as split plots in a randomized complete blocks design with three replications at Islamic Azad University Research Station, Tabriz Branch was carried out in 2017. Experimental treatments were water deficit tension at three levels of 50, 75 and 100 percent of available moisture and spraying with titanium dioxide nanoparticles at four levels of zero, 0. 01, 0. 03 and 0. 05 percent. The results showed that the effect of water deficit tension on hydrogen peroxide enzyme activity, relative humidity content, ear yield and ascorbic peroxidase was significant. Also, the effect of foliar application with nano titanium dioxide was significant on all studied traits and on the interaction of water deficit tension and foliar application with nano dioxide except for relative humidity content in other studied traits. Application of nano titanium dioxide at 0. 01 percent concentration in all treatments increased catalase, Ascorbate peroxidase and hydrogen peroxide enzymes but foliar application of nano dioxide at 50 percent humidity had the highest activity of catalase enzymes., Ascorbate peroxidase had the lowest amount of hydrogen peroxide. Also, foliar application of 0. 01 percent nano titanium dioxide under complete irrigation conditions compared to non-foliar application of this compound under conditions of 50 percent available moisture and control increased maize yield by 58 and 1. 8 percent, respectively. Overall, foliar application of 0. 01 percent nano titanium dioxide concentration in water deficit tension conditions increased the activity of enzymes related to reducing the destructive effect of tension and eventually resulted in higher yield of maize under similar conditions and no use of this compound.
