Abstract
In this study we were interested in assessing the impact of nanoparticles based on ZnO and
their effects on the physiological and biochemical parameters of durum wheat (Triticum turgidum ssp.
Durum). The impact of ZnO is evaluated in three wheat varieties (Boussallem, Gtadur and Ouarsenis), varieties are represented by V1, V2 and V3 through a range of physiological and biochemical parameters achieved in the laboratory. The selected varieties were exposed to increasing concentrations of ZnO nanoparticles (0.01mg / ml, 0.05mg / ml, 0.1mg / ml, 0.5mg / ml).
Preliminary results show that the presence of ZnO-based NPs can have a stimulating effect inhibitor according to the concentration and the effect parameter studied; Thus exposure to low concentrations induce d the reduction of levels of chlorophyll (chlo has chlo b), unlike the high concentrations caused the elevation of these levels mainly in the (chlor a). The presence of nanoparticles caused oxidative stress resulting in the accumulation of Lipoperoxydes (MDA) recorded in all studied varieties, following
exposure to different concentrations. On the other hand a varietal effect has contributed greatly in the variation of the remaining parameters related to ROS (carotenoids, APX and CAT).
Keywords: Nanoparticles, ZnO, oxidative stress, durum, concentrations, plant species
