Evaluation of the impact of different rootstocks on the vigour and drought tolerance of Pinot blanc: a case study in the Rheingau, Germany

Rootstocks play a crucial role in vine cultivation, influencing factors such as vine vigour, disease resistance and adaptation to different soil types and climates. Understanding the genetic background of rootstocks and their parent species is essential for selecting appropriate varieties and optimising vineyard management practices. Furthermore, understanding the parental species provides insight into the selection and breeding processes used to develop rootstock varieties with the desired traits and adaptability. Overall, this research underlines the importance of rootstocks in modern viticulture and highlights the need to continue to explore and utilise different parental species to further improve vine resilience and productivity in different growing regions. The study was conducted in the Rheingau region, Germany with the observation of different physiological parameters of grapevines in rainfed condition.
