Interactive effect of zinc oxide nanoparticles (ZnO NPs) and brassinosteroid on accumulation of Zinc in tomato seedlings. Tomato seeds after sprouting were placed on ½ MS medium containing 5 nM 24-epibrassinolide (BR) and/or 10 and 50 mg/L ZnO NPs (NP10 and NP50, respectively) and cultured for 15 days before the analysis of Zn content. The data shown here are the averages of four replicates, with the standard errors indicated by the vertical bars. The means denoted by the same letter did not significantly differ at a P < 0.05, according to Tukey’s test.
