(A) Changes in soluble sugars, and (B) soluble proteins (mg g− 1 DW) in 7 day-old seedlings of Nubaria 4 variety of faba bean (Vicia faba L.) as affected by seed presoaking for 6 h in different concentrations of nano titanium (TiO2NPs ≈ 12.8 nm) solution at 0.0, 1, 5, 10, 25, 50 and 100 µM and grown at 25 °C ± 0.5. Each value represents the mean of 3 replicates. Different letters indicate significant differences between treatments (Duncan test p ≤ 0.05). Vertical bars represent ± SE.
