Updated knowledge of the vine rootstocks

For some time, the use of rootstocks in viticulture is no longer considered only as a means of agronomic method to avoid the phylloxera damages (Daktulosphaira vitifoliae), but as a tool to be able to influence the physiology of the cultivars and to adapt the vine’s behavior to the different soil conditions, the climatic characteristics and the cultivation techniques.In particular, it is increased the need to use the rootstock as a means to control the physiological processes of the plant, being the root activity closely related to that of the canopy, by exchanging signals and metabolites.
