Canopy Design Drives Photosynthetic Performance, Light Environment, and Fruit Quality in Peach (<i>Prunus persica</i> L. Batsch).

ABSTRACT: Training system selection critically influences peach orchard productivity through its effects on canopy light environment, physiological responses, and fruit quality. This study evaluated two contrasting training systems: a 2D planar fruiting wall system (Four-Axis, 1020 trees ha^-1) versus a 3D Quad-V system (590 trees ha^-1) using two peach cultivars, fresh table 'Platibelle' and clingstone 'Mirel' in Central Macedonia, Greece. Comprehensive physiological measurements including leaf gas exchange, chlorophyll fluorescence, and fruit quality parameters were assessed across two canopy zones (lower 0-1.2 m vs. upper 1.8-3.3 m) during the 2023 and 2024 growing seasons. Results demonstrated that the 2D system achieved superior leaf area index (LAI), but lower light interce
