Special Issue Information

Dear Colleagues,

According to WMO and IPCC, the world has experienced unprecedented high-impact climate extremes over the past few decades with droughts, floods, and heat waves occurring in all parts of the world. Under this changing climate, as the quality and yield of grapevine are directly linked with local climate variables through the terroir expression, wine-growing regions now perfectly suited to a given cultivar may become less so. However, the potential impact of spatially heterogeneous climate changes on grapevine physiology is still largely unknown. Understanding the physiological and metabolic response of plants to challenging environments is essential for preventing and mitigating possible negative effects on yield and grape quality. As stresses involve simultaneous physiological alterations, a comprehensive characterization of the role of metabolic pathways in stress response requires high-throughput data and genome-scale approaches. Moreover, in different wine growing regions, mitigation strategies have been adopted in order to overcome the effects of the excessive temperatures and water stress (antitranspirants), and to delay the maturation in early ripening grapevine varieties (late apical shoot trimming or leaf removal). Such techniques determine modifications in plant physiology and grape maturation with transcriptome reprogramming and metabolite metabolism shifts that need to be understood. This Special Issue of Plants will highlight the mechanisms of regulation of grapevine physiology, organ metabolism, source-sink signaling, hormone crosstalk, and whole-plant ecophysiological responses to abiotic stresses expected in current and future climate change scenarios.

The co-application of N and Fe can improve wine grape composition and promote the formation of flavor compounds. To understand the effects of foliar co-application of N and Fe on wine grape quality and flavonoid content, urea and EDTA-FE were sprayed at three different developmental stages. Urea and EDTA-Fe were sprayed during the early stage of the expansion period, at the end of the early stage of the expansion period to the late stage of the veraison period, and during the late stage of the veraison period. The results demonstrated that the co-application of urea and EDTA-Fe, particularly N application during the late stage of the veraison period and Fe application during the early stage of the berry expansion period (N3Fe1), significantly improved grape quality. Specifically, the soluble solid content of berries increased by 2.78–19.13%, titratable acidity decreased by 6.67–18.84%, the sugar-acid ratio became more balanced, and yield increased by 13.08–40.71%. Further, there was a significant increase in the relative content of amino acids and flavonoids. In conclusion, the application of Fe and N fertilizers at the pre-expansion and late veraison stages of grapes can significantly improve the quality and yield of berries; ultimately, this establishes a foundation for future improvement in the nutritional value of grapes and wine.
