In Vitis vinifera L., the same genotype can express different phenotypic characteristics depending on the environmental conditions, e.g. soil deepness. Wood anatomy, specifically xylem vessel traits, provide information about the plant?s eco-physiological responses to the environment. Slight changes in vessel diameter and density may impact plant hydrosystem functionality, since large vessels are more efficient in the volume of transported water compared to narrower ones, although the latter are more effective in avoiding stress-induced embolism. The aim of this study was to analyze variations in the wood hydraulic structure of three grapevine cultivars, induced by soils with strong contrast in depth, texture and rock volume, providing evidence of their adaptative capacities.
