Post-budburst hand finishing of winter spur pruning can delay technological ripening without altering phenolic maturity of Merlot berries

摘要

Background and Aims Global warming can lead to technological ripening occurring in advance of phenolic maturity for red wine cultivars. This study evaluated the effect of post-budburst winter pruning on the phenology, yield components, berry composition and phenolic maturity in Vitis vinifera L. cv. Merlot.
