This study systematically evaluates the impact of 6PPD (10 to 400 μg L⁻¹) on seed germination, seedling growth, nutrient accumulation, oxidative stress, and metabolic responses in wheat (<em>Triticum aestivum</em> L.). The findings demonstrate that 6PPD significantly inhibits seed germination, with rates declining by 19.64 % to 42.26 % across tested concentrations. Seed vigor and sprout length were notably reduced at higher concentrations (200 and 400 μg L⁻¹) (<em>p</em> &lt; 0.05). Exposure to 400 μg L⁻¹ 6PPD suppressed chlorophyll content and shoot biomass, indicating disruptions in photosynthetic efficiency and growth. Nutrient analysis revealed a biphasic response, with increased Cu, Mg, Mn, and Zn in leaves at lower 6PPD concentrations (10, 50, and 100 μg L⁻¹) and significant reductions in Cu at higher concentrations (200 and 400 μg L⁻¹) (<em>p</em> &lt; 0.05). Elevated reactive oxygen species (ROS) levels, correlating with increasing 6PPD concentrations, indicated severe disruption of the antioxidant defense system.
