Addressing these gaps could lead to more sustainable and effective canopy management strategies. The changing climate poses significant challenges to viticulture, necessitating adaptive canopy management strategies to maintain and enhance grape yield and quality. Climate change impacts, such as increased temperatures and altered precipitation patterns, require innovative approaches to canopy management. For instance, canopy management practices that optimize solar radiation exposure can enhance flavonoid biosynthesis, crucial for grape quality, although care must be taken to avoid degradation of these compounds (Torres et al., 2020). Additionally, strategies that combine shoot thinning with preanthesis defoliation have shown potential in regulating vine yield and improving grape quality by increasing sugar concentrations (Silvestroni et al., 2016). As climate conditions continue to evolve, the development of canopy management practices that are resilient to these changes will be essential for sustaining grapevine productivity and quality. 10 Conclusion The role of canopy management in optimizing grapevine yield and quality is pivotal, as it directly influences the microclimate within the vineyard, which in turn affects both the quantity and quality of grape production. Key findings from various studies highlight that effective canopy management practices, such as shoot thinning, leaf removal, and the use of specific training systems, can significantly enhance grape yield and quality. For instance, optimal canopy density, typically around three leaf layers, is crucial for balancing light exposure and shading, which are essential for improving fruit composition and wine quality. Additionally, practices like shoot trimming and cluster thinning have been shown to improve berry ripening and reduce issues like bunch rot, thereby enhancing the overall quality of the grapes. For viticulturists and industry stakeholders, it is recommended to adopt a tailored approach to canopy management that considers the specific environmental conditions and grapevine varieties. Techniques such as shoot thinning combined with preanthesis defoliation can be particularly effective in increasing sugar concentrations and regulating vine yield over the long term. Moreover, in rainfed vineyards, strategies like reiterate shoot trimming can help adapt plant growth to soil water availability, thereby preserving wine quality without compromising yield. It is also advisable to explore innovative solutions like biostimulants, which have shown promise in enhancing grape color and quality under challenging climatic conditions. By implementing these strategies, viticulturists can optimize grapevine performance, ensuring high-quality grape production that meets market demands.
