Fig. 4From: Comparative morpho-physiological and biochemical responses of Capsicum annuum L. plants to multi-walled carbon nanotubes, fullerene C60 and graphene nanoplatelets exposure under water deficit stressChange in the electrolyte leakage index 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 testBack to article page
