Abstract

In semi-arid regions like Mendoza, Argentina, climatic conditions such as low precipitation, irregular rainfall distribution, high evapotranspiration, hailstorms, and extreme temperatures pose significant challenges to plant production. The objective of this study is to explore the influence of two colors of anti-hail nets on the water status of vineyards. δ13C and the physicochemical composition of grapes were used as indicators during the ripening-harvest period. The methodology involved sampling berries from Malbec grape vines covered with two colors of anti-hail nets (pearl and black) in a plot located at the INTA Rama Caída Experimental Station, San Rafael, Mendoza, Argentina. The main results showed that the black anti-hail net was more favorable for the vineyards' water status, while the pearl net resulted in larger grapes with higher soluble solids concentration. Understanding these effects is crucial for optimizing water use in viticulture, particularly in arid regions where water is scarce and vital for sustainable production.
