Potential and Actual Bud Fruitfulness: A Tool for Predicting and Managing the Yield of Table Grape Varieties

Microscopic bud dissection can be used to assess grapevine fruitfulness prior winter pruning and long before actual measured in the vineyard following spring. Bud dissections should performed by qualified trained personnel because inflorescence primordia are difficult distinguish some varieties. In Puglia region, Southeastern Italy, 2018 2019, potential using observed were compared for seventeen table grape The percentage of fertile buds, number (IP) per node, incidence primary necrosis (PBN) detected with either managing or predicting yield during successive season. data successively buds varieties examined had similar values both vineyard. application longitudinal sections an alternative approach (or integrated into traditional cross sections) IP varieties, but two techniques together more repeatable results. technique (with provide useful insights viticulturist help guide (intensity canes) predict yield.
