Summary
This study synthesised and characterised a novel lignin nanoparticle-zinc oxide hybrid material (ZnO@LNP) and demonstrated its application as a seed primer for maize for the first time. When applied to seeds, the material promoted early seedling development, enhanced accumulation of photosynthetic pigments and phenolic compounds, and reduced oxidative stress markers in young maize plants. The work presents exploratory evidence for hybrid nanoparticle technology as a potential seed treatment bio-activator, though field-level efficacy and agronomic significance remain to be established.
UK applicability
The findings are relevant to UK cereal production systems as a potential innovation in seed treatment technology. However, the study was conducted at laboratory and controlled seedling scale; field validation under UK growing conditions, assessment of agronomic yield impacts, and regulatory approval for nanoparticle agricultural use would be necessary before practical application.
Key measures
Thermal stability (TGA), surface hydrophilicity (contact angle), antioxidant activity, zinc release kinetics, chlorophyll content, carotenoid content, anthocyanin content, total phenol content, lipid peroxidation levels, seedling biomass development
Outcomes reported
The study evaluated physicochemical properties of synthesised ZnO@LNP hybrid nanoparticles and their effects when applied as a seed primer on maize seedling development, photosynthetic pigment accumulation, and oxidative stress markers.
