Abstract:
The productivity of wheat, a vital crop in South Asia, is severely threatened by soil salinity. This study evaluated the potential of green-synthesized nanoparticles (NPs) to ameliorate salt stress during seed germination. Zinc oxide (ZnO), magnesium oxide (MgO), and magnesium-doped ZnO (Mg-ZnO) NPs, fabricated using a Tribulus terrestris L. extract, were applied at 5 mg/L and 25 mg/L concentrations under saline conditions (0-0.2 M NaCl). Physiological assessments revealed that Mg-ZnO NPs at 5 mg/L were optimal for overall seedling vigor across all stress levels. Under severe salinity (0.15-0.2 M), the lower concentration (5 mg/L) of all NPs was more effective, while higher concentrations (25 mg/L) benefited germination under mild stress. The results confirm the efficacy of green-synthesized NPs, particularly Mg-doped ZnO, as a promising nano-priming strategy for enhancing salinity tolerance in wheat. Future work should focus on large-scale application methods and environmental safety assessments.
