Abstract: (100 Views)
Among the toxic heavy metals is cadmium, which is considered as a potential risk for humans and other organisms and requires more attention to prevent this metals to entering the food chain. In recent years, along with the development of nanotechnology, it has been used to advance environmental goals. In order to study the effect of zinc oxide- and titanium dioxide-nanoparticles on white grape (cv. Sultana) seedlings under Cd stress, a factorial experiment was conducted based a completely randomized design with three replicates. The first factor was cadmium stress at three levels (0, 50 and 100 mg/kg soil) and the second factor was the spraying of the nanoparticles of zinc oxide and titanium dioxide at 3 levels (0, 50 and 100 mg L-1). The results showed that cadmium stress significantly reduced the growth parameters and photosynthesis pigments, and increased H2O2 and malondialdehyde (MDA) contents and antioxidant enzymes activity of guaiacol peroxidase (GPX) and super oxide dismutase (SOD). Foliar application of zinc oxide- and titanium dioxide-nanoparticles improved morphological characteristics, photosynthetic pigments and enzymatic antioxidants but reduced MDA and H2O2 contents under cadmium stress. Based on the results of this research, it seems that foliar spraying the nanoparticles of zinc oxide and titanium dioxide (especially at the concentration of 100 mg L-1), can improves the growth, photosynthetic pigments and antioxidant enzymes activity under cadmium stress, and increases plant tolerance to harmful effect of this toxic metal in grape cv. Sultana.
