Abstract

Effect of metal oxide nanoparticles on calli of two wheat varieties: Parabola (stress tolerant) and Raweta (sensitive) was studied. ZnO induced 10% larger membrane damage in Raweta calli. TiO2, Al2O3, and ZrO2 caused nearly 30% greater lactate dehydrogenase leakage for Raweta compared to Parabola. UV-irradiation of samples containing ZnO particles intensified this effect. Membrane lipid peroxidation in ZnO treated Raweta calli was twice as high as in Parabola and further increased after UV-irradiation. TiO2, Al2O3, and ZrO2 nanoparticles caused a 4-fold increase in malondialdehyde concentration in Raweta calli in comparison to Parabola calli. The nanoparticles studied damaged the cellular defense system by inactivating the antioxidative enzymes.
