Falanghina Grapevine (<i>Vitis vinifera</i> L.) Yield and Berry Quality under Different Pedoclimatic Conditions in Southern Italy

Abstract

Climate is a determinant driver for grapevine geographical distribution, influencing yield and berry quality. The current environmental changes are intensifying the need to improve the knowledge of the soil–plant–atmosphere system in the vineyard, to properly manage cultivation factors and to increase berry yield and quality. Since most of the berry growth and ripening phases occur during the driest period in the Mediterranean area, increasing environmental constraints are expected to impose more and more limitations on grapevine productivity and finally on wine quality. The aim of this study was to evaluate whether different pedoclimatic conditions in four proximally located vineyards of the Campania Region in Southern Italy determine differences in crop yield and must quality of Vitis vinifera L. subsp. vinifera “Falanghina”. This study was conducted over three growing seasons, by monitoring vine growth and characterizing yield and must quality. The overall results showed differences in yield and berry quality characteristics for the four vineyards, with the field CA (Calvese) and GR (Grottole) showing pedoclimatic conditions limiting growth and yield compared to SL (Santa Lucia) and AC (Acquefredde).
