Dataset on "Effect of nano size Cu particles on Cu uptake, accumulation and oxidative stress in cowpea"

These data are the refined data set for an article published on the impact of nano-copper particles (< 25 nm and 60–80 nm) on Cu uptake, bioaccumulation (roots, leaves and seeds), activity of ascorbate peroxidase (APX), catalase (CAT), superoxide dismutase (SOD), glutathione reductase (GR), and lipid peroxidation in leaves and roots of Vigna unguiculata (cowpea) in soil medium. Plants were exposed to four levels (0, 125, 500 and 1000 mg/kg) of 25 nm or 60–80 nm nano-Cu for 65 days. Conclusively from the study, APX- and GR-activity level could be a useful predictive biomarker of nano-Cu toxicity in cowpea.
