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.
