Change in the rate of photosynthesis (A), stomatal conductance (B), and chlorophyll b (C) of bell pepper plants exposed to different types of nanomaterials (fullerene C60, multi-walled carbon nanotubes and graphene nanoplatelets) at different concentrations (0, 100, 200 and 1000 mg/L) under drought stress intensities [(50%, 75%, and 100% (control) of field capacity (FC) moisture)]. The values reported are means ± SD (n = 3) and the Bars with different letters show significant difference among employed treatments at P < 0.05 probability level using Duncan’s test
