INFLUENCE OF THE INTERACTION SCION X ROOTSTOCK ON GRAPEVINE RESPONSE TO DROUGHT STRESS AS A TOOL IN NEW GRAPEVINE ROOTSTOCKS BREEDING PROGRAMS.

description: Viticulture is expected to face several challenges related to current and future climate changes. Particularly, the vine-growing areas experiencing severe drought stress are expected to increase in the coming years. This could affect grape quality and yield, as well as the character and style of wines, and, more generally, the viticultural potential of many regions. Many studies suggest adaptive strategies to address changing environmental conditions, and the use of drought-tolerant rootstocks is considered an effective mid-term solution to mitigate and manage these negative impacts. However, the range of available rootstocks is limited, and most of them were selected in the late 19th century, when grapevine cultivation practices vastly differed from those of today. As a result, there is a growing demand for drought-tolerant rootstocks that are suitable for modern viticulture. In response to this request, some new genotypes have been released in recent years. Among those, the M-series by University of Milano has shown promising performances in different viticultural contexts. A deep insight into the behaviour of these new rootstocks under water stress conditions, especially in comparison to traditional ones, could provide valuable information, useful at different levels. On one hand, a better understanding of rootstocks performance under drought stress would support winegrowers in making informed decisions when planning new vineyards. On the other hand, it would provide breeders with crucial data on the grapevine responses to water stress, with particular regard to the complex interaction between scion and rootstock, allowing them to better direct their research efforts. To address these questions, three experiments were conducted. The first study evaluates the scion x rootstock interaction effect on drought tolerance, considering two grapevine varieties characterized by different physiological strategies against water stress.
