(A) Schematic illustration of measurements of tobacco after Mo NPs exposure; Morphological effects of Mo NPs on tobacco seedlings and their roots after root irrigation (B) and foliar spraying (C) for 25 days; Tobacco agronomic characters of (D) fresh weight, (E) plant height, (F) dry weight and (G) root length after different treatment methods. Data are means ± SD (n = 5), ∗ and ∗∗ indicate significant differences between the control and Mo NPs treatment at p< 0.05 and p< 0.01 levels according to one-way ANOVA followed by Tukey’s test.
