Table 2.
Maximum ribulose 1,5-bisphosphate carboxylation rates (Vcmax), maximum electron transport rates (Jmax) and CO2 compensation points determined for Pisum sativum L. plants grown under the sole or combined CeO2 and ZnO NPs treatments. Distinct letters show the statistically significant differences among treatments as calculated with Tukey’s HSD post hoc test (p = 0.95), n = 6.
