The morphological differences between control and treated calluses. Experiment A: (a), (b), (c), and (d). Experiment B: (e), (f), (g), and (h). Control calluses for experiment A and experiment B are (a) and (e), respectively. Calluses treated with 0.5 mg/l iron oxide NPs are (b) and (f); with 1 mg/l iron oxide NPs (c) and (g); with 1.5 mg/l iron oxide NPs (d) and (h).
