Figure 5.

Copper (a), manganese (b), iron (c), magnesium (d), calcium (e), and potassium (f) concentrations in roots and shoots of Pisum sativum L. grown under the sole or combined CeO₂ and ZnO NPs treatment. Concentrations of nanoparticles are given in mg/L of elemental cerium and zinc, respectively. The cultivation time was 12 days. Vertical bars represent standard deviations (n = 6). Distinct letters show the statistically significant differences among treatments as calculated with Tukey’s HSD post hoc test (p = 0.95).
