Foldable lyre impacted the agronomic performance and phenolic profiles of ‘Merlot’ grapes cultivated in a humid temperate climate
The training system plays a key role in viticulture, influencing canopy structure, yield, grape and wine composition. This study evaluated the impact of vertical shoot positioning-VSP and foldable lyre training systems set at 20°, 30°, and 40° angles, on the production and biochemical profiles of ‘Merlot’ grapes at Ser...
