Abstract

Zinc oxide nanoparticles (ZnONPs) have attracted significant attention in agricultural research due to their potential to enhance plant growth and improve stress tolerance. Their nanoscale properties enable increased bioavailability, facilitating essential zinc uptake, which plays a crucial role in enzymatic activity, photosynthesis, and overall metabolic function. However, excessive nanoparticle exposure may induce oxidative stress, disrupting cellular homeostasis. This study explores the impact of ZnONPs on Brassica oleracea var. capitata (white cabbage), assessing germination, biomass accumulation, chlorophyll synthesis, and oxidative stress markers at different ZnO NP concentrations (0, 25, 50, and 100 mg/L). Results indicate that lower concentrations (25 and 50 mg/L) enhance plant growth parameters through improved nutrient assimilation and chlorophyll biosynthesis. However, at 100 mg/L, a significant increase in malondialdehyde (MDA) levels and antioxidant enzyme activity suggests oxidative stress, likely due to reactive oxygen species (ROS) generation. The study underscores the dual role of ZnO NPs as both growth stimulators and potential phytotoxic agents, depending on concentration. Findings highlight the necessity of precise nanoparticle dosage in agricultural applications to harness their benefits while mitigating adverse effects.
