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

Figure 5

The effect of different concentrations of nano-TiO₂ or nano-ZnO (5 and 10 mg/L) on total soluble sugar (a), proline (b), and free amino acids (c) 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.
