Grape production is very sensitive to extreme temperatures. Over the current century, temperatures are predicted to continue rising with adverse impacts on viticulture. These impacts range from short-term effects on wine quality to long-term consequences such as the sustainability of vineyards in traditional wine regions. Certain viticultural regions may not be ideal for growing wine grapes in the not-so-distant future. For the wine-making industry to survive, it is crucial to develop heat stress-adapted genotypes or identify and utilize stress-tolerant germplasm. Grapevines have developed mechanisms to maintain homeostasis and tolerate thermal stress and water scarcity. These mechanisms include physiological adaptations and the initiation of signaling pathways and gene regulatory networks that modify the heat stress response.
Field measurements show that high temperatures alter grapevine physiology, decreasing stomatal conductance and the average photosynthetic rate. Grape berry metabolism and juice quality are also affected, as elevated temperatures disturb several metabolic pathways, resulting in berries with lowered acidity and increased sugar content, and ultimately, unbalanced wines. This Research Topic explores the physiological and chemical response of grapevines and grape berries to heat stress and water scarcity. The role of heatwaves and excessive solar radiation is also investigated, as well as grape quality, namely secondary metabolite accumulation in berries. This topic also explores solutions to improve the sustainability of vineyards in a changing climate, including precise irrigation scheduling, the re-evaluation of trellising, cultural canopy management strategies, and the use of preventative measures to improve canopy micro-climate. Also taken into consideration are issues of spatial variability due to natural variability in vineyard soil, and the use of proximal/remote sensing technologies in topography and vineyard layout designs.
All types of articles (Original Research, Opinions, Perspectives, Methods, and Reviews) are welcome. And the topics should address the following aspects:
• Cultivars (from breeding or originated from warm/hot climates) evaluation on suitability for the warming trend;
• Evaluation of meteorological approaches to enhance the accuracy and precision of predicting vineyard climate fluctuation and extreme weather events;
• Modifying viticultural techniques and cultural practices to avert the negative effects from climate change;
• Improvement on the resiliency against climate change by using precision agriculture technologies;
• Soil and water management to improve adaptability to climate change;
• The effects of climate change on grapevine and berry ripening at molecular biological level;
