Seed germination and morphometric analysis. Effects of two concentrations (50 mg kg−1 and 100 mg kg.−1) of nanomaterials on germination and growth of Vicia faba. A Germination rates of faba bean seeds in in vitro conditions. The results are expressed as percentage with respect to the control (CNT), considered as unit (100%), and represent the mean ± S.E. of three different experiments. B Measurements of the plant length, expressed in cm, of seedlings grown in the presence of the nanomaterials. Data are reported as mean ± S.E. of three independent measurements. C Representative images of the samples exposed to the high doses of the several treatments (the scale bar indicates 10 cm). The asterisks denote significant differences of the samples from the respective controls (one-way ANOVA/LSD test; **p < 0.01, *p < 0.05)
