Changes in the morphological and physiological parameters and the trend of each parameter in response to size and concentration of (Fe3O4) NPs-treated plants as compared to control plants. Shoot height (cm) (a and b); Root length (cm) (c and d); Leaf area (cm2) (e and f); Chlorophyll content (g and h). (P < 0.0001 for all parameters) in response to (Fe3O4) NPs and their concentrations. * indicates values that are significantly different from the control (Post-hoc tukey test with P < 0.05)
