Abstract
The integration of agrivoltaic (AV) systems in Mediterranean vineyards is gaining attention as a strategy to mitigate climate change impacts while maintaining agricultural productivity.
This study evaluated agronomic and physiological responses of Vitis vinifera L. ‘Primitivo’ to photovoltaic shading, focusing on leaf morphology and plant water status.
Field trials were conducted in 2024 in Puglia (southeastern Italy) under three light regimes: full sunlight (control), moderate shading, and higher shading from fixed photovoltaic panels.
Leaf area, leaf fresh weight, net CO2 assimilation, and stem water potential were monitored throughout the growing season.
Shaded vines showed significant increases in leaf area and fresh weight compared with the control.
Despite reduced radiation, net CO2 assimilation remained stable or slightly higher under shading at mid-season, while shading improved vine water status, maintaining less negative stem water potential toward late season.
These results indicate that agrivoltaic systems can mitigate Mediterranean climate stress and enhance grapevine physiological performance, supporting their potential to integrate renewable energy with sustainable viticulture.
