In recent years, there has been a lot of attention in the use of multi-walled carbon nanotubes (MWCNTs) in farming. This study is aimed to see the effect of MWCNTs at various concentrations such as 30, 60, 90, 120, and 150 parts per million(ppm) and their impact on antioxidant activities including CAT (Catalase), SOD (Superoxide dismutase), POD (Peroxidase), and DPPH (2,2-diphenylpicrylhydrazyl) in15 days old pearl millet seedlings. Seeds were treated to MWCNTs using priming method. In result we noted the gradual increase in CAT activity with the increasing concentration upto 90 ppm (0.71mg) H2O2 destroyed/ sec./gmF.wt. and then it decreased with an increase in concentration. At 60ppm, POD activity was found to be the highest with 0.62μM/L/gm/sec.F.wt. and SOD activity increased till 90 ppm (0.63 unit/mg). DPPH inhibition activity was obtained 72.65% at 90 ppm to be maximum, whereas with the increase of the concentrations there was decline in DPPH activity. In conclusion the study showed MWCNTs works excellent at an optimal concentration in enhancement of antioxidant activities in developmental stage of seedling growth and shown negative results when concentrations were increased. These results suggested that the specific concentration of CNTs could help in the overall growth of the plant with the highest yield in terms of quality and quantity.
