Changes in biochemical parameters and the trend of each parameter in response to size and concentration of (Fe3O4) NPs-treated plants as compared to control plants . Sugar content [mg/L] (a and b). Protein content [% (f.m)] (c and d) as compared to control plants. (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)
