IMPACT OF ZINC OXIDE NANOPARTICLES UNDER LEAD TOXICITY ON CHILLI
Abstract
Capsicum annuum L., a widely cultivated and nutritionally dense crop, holds historical, culinary, and medical significance. The principal active ingredient, capsaicin, is known for its antioxidant, analgesic, and anti-inflammatory activities. Advances in nanotechnology, notably zinc oxide nanoparticles (ZnO-NPs), have shown promise in increasing crop yield. ZnO nanoparticles promote plant germination, root and shoot growth, nutrient uptake, and stress tolerance. However, large amounts might result in oxidative and genotoxic damage, needing careful treatment. Heavy metal contamination, particularly lead and cadmium, greatly reduces agricultural productivity and quality. ZnO-NPs reduce heavy metal toxicity by increasing antioxidant activity, photosynthesis, and metabolic activities. Studies on numerous crops, such as chili and tomatoes, highlight the advantages of optimal ZnO-NP application for sustainable agriculture. Despite promising findings, comprehending the precise mechanisms of ZnO-NPs and mitigating their phytotoxic effects remain essential for their widespread agricultural use.
