Abstract :Titanium dioxide nanoparticles insert ignore into journalissuearticles values(TiO2-NPs); among metallic NPs are one of the most produced and consumed NPs in the world. Thus, TiO2-NPs release into the environment is inevitable. Their impact on food source cereals is still unclear. The purpose of this study was to assess the phytotoxic impacts of TiO2-NPs on growth and some mineral nutrient insert ignore into journalissuearticles values(zinc insert ignore into journalissuearticles values(Zn);, iron insert ignore into journalissuearticles values(Fe);, manganese insert ignore into journalissuearticles values(Mn);, copper insert ignore into journalissuearticles values(Cu);, nitrogen insert ignore into journalissuearticles values(N);, phosphorous insert ignore into journalissuearticles values(P);, potassium insert ignore into journalissuearticles values(K);); uptake of the wheat insert ignore into journalissuearticles values(Triticum vulgare L.); plant. The TiO2-NP suspensions at increasing concentrations insert ignore into journalissuearticles values(0, 5, 10, 20 and 40 mg L-1); were applied to wheat plant Yunus cultivar grown in hydroponic culture under controlled conditions for 21 days. The results indicate that the TiO2-NPs have not statistically significant effects on plant growth. The chlorophyll content was decreased with increasing TiO2-NP treatment, except for 5 mg L-1 TiO2-NPs treatment. The higher N insert ignore into journalissuearticles values(4.58%);, P insert ignore into journalissuearticles values(0.78%);, Zn insert ignore into journalissuearticles values(87.50 mg kg-1);, and Cu insert ignore into journalissuearticles values(12.90 mg kg-1); concentration were recorded at 40 mg L-1 TiO2- NPs treatment. On the other hand, K concentration was decreased at 20 and 40 mg L-1 TiO2-NPs treatments. This study has shown that exposure to TiO2-NPs causes no significant phytotoxic effect on wheat.
