Description
Guangling Shi and eight co-authors spray grapevines with nano iron plus a phosphate salt to lift fruit quality. Marselan grapes are grown for wine, and their color and health compounds set much of their value. Their 2026 study applied the pair to leaves and tracked what changed in the berries. Measures covered sugar and acid balance, color compounds, scent compounds, and how well the leaves captured sunlight.
The combined spray raised photosynthesis and the uptake of iron and phosphorus together. Berries gained in sweetness balance and in phenolic compounds, which drive color and antioxidant value. Gene and chemical profiling showed a broad rewiring of the fruit's secondary chemistry. The authors present nano-scale feeding as a precise tool for growers, while noting that how it works at the gene level is still being mapped.
