Canopy structure plays a critical role in regulating light distribution, photosynthetic efficiency, and ultimately fruit quality in grapevines. This study systematically reviews the characteristics of different canopy architectures and their effects on the vineyard light environment. It further analyzes how variations in canopy density and spatial configuration influence leaf photosynthesis, including differences among canopy layers and the accumulation and transport of photosynthates. The relationship between canopy structure and key fruit quality parameters, such as sugar content, organic acids, and secondary metabolites, is also discussed. In addition, common canopy management practices, including pruning, leaf removal, and training systems, are evaluated for their effectiveness in optimizing canopy microclimate. Case studies comparing different training systems and management strategies highlight practical approaches to improving grape quality. The interactions between canopy structure and environmental factors, such as light, water, and nutrients, are also addressed. Overall, this study provides a theoretical basis and practical guidance for optimizing canopy structure to enhance grapevine productivity and fruit quality.
