Universidade de Lisboa / Faculdade de Ciências. Universidade do PortoThe effects of global warming have led to increased evapotranspiration losses, modified and more erratic precipitation patterns and increased risks of severe water stress. These events have a negative impact on viticulture but also stimulate the search for alternative solutions for vineyard management. Some of these solutions involve novel irrigation strategies and improved knowledge on grapevine stress physiology. Therefore, this thesis aims to introduce the topic of irrigation frequency as an additional strategy to develop an adequate irrigation strategy, which can influence distribution of water and roots in the soil, influence water use efficiency (WUE) as well as the dynamics of berry ripening while contributing for water savings. This review summarizes grapevine responses to water stress, examining major changes in physiological and molecular processes and analyzing the effects on WUE. The tolerance mechanisms implemented by grapevine to respond to increased leaf temperature and the antioxidant protective systems activated to counteract adverse conditions, are reviewed. Some of the most important methods to monitor plant and soil water status are shortly described and explained. In addition, the effect of deficit irrigation strategies and the role of irrigation frequency on vine’s performance are discussed. The review of literature showed that irrigation frequency has a major impact on stomatal control, resulting in a purely hydraulic regulating mechanism in the case of high irrigation frequency and the grapevine transpiration tends to drop drastically once the effect of irrigation water disappears. However, under identical growing conditions, low irrigation frequency, associated with a consistent water volume, could activate hormonal stomatal regulation mechanism, mediated by the ABA signal. In this case, grapevine’s transpiration tends to decrease moderately, over a longer period, which will positively affect berry volume and sugar accumulation rates.n.Costa, Joaquim MiguelLovisolo, ClaudioRepositório da Universidade de LisboaCavallini, Simone2022-09-09T09:58:24Z20212021-01-01T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisapplication/pdfhttp://hdl.handle.net/10400.5/25452TID:203082141engCavallini, S. - Effects of irrigation frequency on water use efficiency and grapevine performance – a review.
