Reconstruction of vine hydraulic behaviour from tree-ring series up to must in Falanghina under different pedo-climatic conditions

In the Mediterranean region, climate-change-driven increasing temperature and frequency of prolonged drought periods are affecting physiological behaviour and vine growth, with consequences on berry yield and quality. Assessing how plants have reacted to past environmental fluctuations can help understanding current plant behaviour and forecast possible responses to climate changes. The improvement of knowledge about the plasticity of morpho-functional traits in vines as response to climatic stress conditions can help the management of vineyards. In this study, we applied a wood-sciences approach to reconstruct past vine hydraulic behaviour in four vineyards of Vitis vinifera L. subsp. vinifera" Falanghina" located in southern Italy (La Guardiense farm, Benevento, Campania region), cultivated in different pedo-climatic conditions onto the same rootstock. Wood cores were extracted by the vine trunk and ...
