This study evaluated the effects of ZnO and green-synthesized nanoparticles (ZnO-NPs) from Sargassum ilicifolium extract on biochemical interactions between tomato leaves destructive pest Tuta absoluta. The average size stability ZnO-NPs were characterized using DLS, X-RD, FE-SEM. Peaks in FT-IR spectrum algae ZnO-NPs, indicated presence carboxyl groups, amines, alkynes alcohols. Treated exhibited increased total chlorophyll anthocyanin contents, particularly at 100 50 ppm, compared to control. A significant increase flavonoid content was observed while phenolic also enhanced ppm. In T. absoluta larvae, exposure ppm led a reduction α-amylase, protease, protein, TAG levels, alongside catalase activity. Additionally, G6PD ALT activities decreased Lactate, MDA, RSSR/RSH Furthermore, elevated larval aldolase activity, AST γ-GT declined. These findings indicate that enhance defense mechanisms mitigate damage, supporting their potential use integrated management strategies against

Zinc Oxide Nanoparticles: Plant Response, Interaction, Phytotoxicity, and Defence

Опубликована: Янв. 1, 2023

Agronomy is the strength of developed countries, with more than 70% people depending on it for their survival. The potency plant to protect itself against risks depends a certain degree its genetic makeup and nutritional status. Many continuous efforts have been made in an attempt eradicate these stresses or even reduce incidence them. Nanotechnology working introduce modern techniques agricultural field, such as enhancing absorption nutrients, identifying diseases early, making smart management improve quality production. Zinc Oxide nanoparticles (ZnONPs) are characterized by bio-availability, low toxicity, high biological activity plants, where they increase activities some enzymes scavenge free radicals. Eventually, ZnONPs shown good effective advantages over other nanomaterials because work support stabilize immune system activate defence response plants.
