In this study, we examined the role of zinc oxide nanoparticles (ZnO NPs) on the growth facet, photosynthetic attributes, lipid peroxidation, electrolyte leakage (EL), and antioxidant activity of basil plants following growth subjected to different levels of sodium chloride-induced salinity [1.0 (control), 2.0, 3.0, 4.0, and 5.0 deci Siemens per meter (dSm–1)]. The foliage of 30-day-old plants was sprayed with an aqueous solution of ZnO NPs [(1.5/2.0 parts per million (ppm)]. Treated plants sampled at 75 days after sowing showed a concentration-dependent response against salinity for all studied growth, photosynthetic attributes, and other biochemical parameters. All growth parameters decreased with increasing salt levels in the soil. However, a direct relationship was observed for lipid peroxidation, EL, and all antioxidant stress markers, and all these parameters increased with the increased salinity levels in the soil. Moreover, ZnO NPs alone (1.5 or 2.0 ppm) or as a follow-up treatment with salinity (2.0 dSm–1 + 1.5 or 2.0 ppm ZnO, 3.0 dSm–1 + 1.5 or 2.0 ppm ZnO, 4.0 dSm–1 + 1.5 or 2.0 ppm ZnO, and 5.0 dSm–1 + 1.5 or 2.0 ppm ZnO) enhanced all the growth and photosynthetic parameters and protected the plants against salinity by reflecting the enhanced activity of antioxidants and decreasing EL and lipid peroxidation. The results of this study confirmed the ameliorating role of ZnO NPs against salt stress and screened out an effective dose of ZnO NPs (2.0 ppm) for growing Ocimum basilicum plant species in saline soil.

Key words: Photosynthetic machinery, salinity, stress markers, sweet basil, ZnO NPs.
