dc.description.abstractViticulture and wine industry are important economic resources for many countries, represented in a wide range of extremely diverse climates all over the world and highly affected by global climate change at different scales. The global warming is the main cause of water sources reduction due to an altered precipitation pattern; this means a reduction in sources of supply and an increase in water demand from crops especially in Mediterranean regions. The high impact of irrigation in grapevine berry quality and yield makes the development of plant water status monitoring systems an essential issue in the context of sustainable viticulture. Knowledge of the physiological responses of the crop and the development of suitable water status monitoring systems are the main prerequisites for proper irrigation management, in order to mitigate climate change effects. This review aims to provide a state-of-the-art summary of the most important literature on grapevine water status assessment for monitoring and adapting vineyard management strategies to production goals in view of global warming. In this work mainly plant-based methods are reviewed, their advantages and drawbacks are discussed. In this work some factors influencing water relations and effects of severe water stress on grapevine are also reported. The main plant-based methods for irrigation scheduling, including those based on direct or indirect measurement of plant water status and those based on plant physiological responses to drought, are outlined and evaluated. New technologies approaches that belong to the field of precision viticulture are also described, which could offer the integration of heterogeneous information collected in the vineyard at different spatial and temporal resolutions. These new approaches offer new synergies to overcome the limitations inherent to plant water status measurement techniques obtained directly or indirectly. The potential of plant-based systems for automated irrigation control using various scheduling techniques is also discussedpt_PT
