Abstract

Projected changes in drought occurrence in the Mediterranean region are rising concerns about the adaptive capability of typically rainfed crops, as grapevine, to increasing aridity. Cultivation management, especially the techniques influencing the hydraulic pathway, can play a role in plant adaptation to drought for the consequent changes in wood anatomical functional traits. The aim of this study was to assess the effect of grafting on wood anatomy in tree-ring series of Vitis vinifera L. 'Piedirosso' grapevine cultivated in a volcanic area in Southern Italy. Tree-ring anatomy was analysed in vines grown on their own-roots or grafted to 420A rootstock. Results showed that grafted vines had higher occurrence of wood traits linked with safety of water transport if compared with non-grafted vines. Grafting induced the formation of tree rings with higher incidence of latewood also characterised by narrower and more frequent vessels if compared with non-grafted vines. This study suggested a different regulation of water flow in the grafted and non-grafted vines. Such findings support the analysis of wood anatomy as a tool to drive decisions linked with plant cultivation management. In this specific case, being grapevine a rainfed crop, results encourage to evaluate the opportunity to move from a traditional cultivation with own-rooted grapevines towards grafted models inducing better adaptation to increasing drought.
