Summary

This research demonstrates that foliar application of zinc oxide nanoparticles can mitigate heatwave-induced losses in rice productivity whilst simultaneously improving grain nutritional quality, mediated partly through beneficial modifications to the phyllosphere (leaf surface microbial community). The findings suggest a novel mechanistic pathway by which nanotechnology may support climate adaptation in staple cereal crops, though field applicability across diverse agroclimatic zones requires further validation.

UK applicability

Direct applicability to UK rice cultivation is limited, as commercial rice production is not established in the UK climate. However, the nanoparticle application strategy and phyllosphere-mediated stress resilience mechanisms may be transferable to other temperature-sensitive UK cereal crops such as wheat or barley under future warming scenarios.

Key measures

Grain yield; grain zinc and nutrient concentration; phyllosphere microbial community composition; plant physiological stress markers under elevated temperature conditions

Outcomes reported

The study examined the effects of zinc oxide nanoparticles applied via the leaf surface on rice grain yield, nutritional composition, and physiological responses under heatwave conditions. Measurements likely included grain yield, zinc content, protein levels, and heat-stress biomarkers in plants.
