Abstract

Canopy architecture plays a crucial role in regulating plant growth, phenology and yield by influencing the microclimatic environment, light interception and resource use efficiency. This review systematically explores the interplay between canopy structure and plant phenological stages, particularly in flower crops. Structural traits such as leaf orientation, plant height, branching pattern and spatial distribution of foliage significantly determine the distribution of light within the canopy, affecting photosynthesis and developmental timing. Variations in canopy architecture have been shown to influence flowering induction, fruit set and yield potential by altering the temperature and light quality perceived by the plant. The review also highlights the hormonal control of canopy traits, with auxins, gibberellins and cytokinins modulating shoot elongation, leaf expansion and apical dominance. Furthermore, it examines practical approaches for canopy manipulation, including spacing, pruning and training systems, aimed at maximizing productivity and enhancing crop performance under varied environmental conditions. The integration of remote sensing tools and canopy modelling techniques is emphasized for real-time monitoring and optimization of canopy performance. Understanding the relationship between canopy design and phenology provides critical insights for breeding programs and precision agriculture strategies. This synthesis underscores the importance of tailored canopy management to achieve sustainable yield improvements and better adaptation to climate variability in flower crops.
