Physiological and Molecular Response of Wheat Cultivars to Titanium Dioxide or Zinc Oxide Nanoparticles under Water Stress Conditions

Figure 4

The effect of different concentrations of nano-TiO₂ or nano-ZnO (5 and 10 mg/L) on chlorophyll a (a), chlorophyll b (b), carotenoids (c), and total pigments (d) of both wheat cultivars (Gimeza 12 and Sids 13) subjected to different levels of water irrigation requirement at 75 days from sowing. TiO₂ 1 = 5 mg/L, TiO₂ 2 = 10 mg/L, ZnO 1 = 5 mg/L, and ZnO 2 = 10 mg/L.
