Manipulating the leaf area to fruit mass ratio alters the synchrony of total soluble solids accumulation and titratable acidity of grape berries

摘要

Background and AimsThis study investigated: (i) the importance of changing the leaf area: fruit mass ratio (LA:FM) by crop removal and/or shoot trimming on total soluble solids (TSS) concentration and content, pH, titratable acidity (TA) and berry mass; (ii) the extent to which changes in LA:FM ratio altered the synchrony TSS:TA ratio; and (iii) whether the responses were consistent for Pinot Noir and Sauvignon Blanc.
