Özet

© 2020 International Society for Horticultural Science. All rights reserved.Crown gall (Rhizobium vitis) is an economically important disease affecting growth of grapevine (Vitis vinifera L.). But the effects of the disease are generally focus on the lack of vine vigour rather than chemistry of berry content. In this study, impacts of crown gall disease on fruit yield and berry quality were investigated in the white wine grape cultivar ‘Narince’ planted in a commercial vineyard. ‘Narince’ vines showing symptoms and non-symptoms were compared. An equal number of 15 vines were evaluated in each group. Juice from grapes were collected at five stages of berry ripening after the onset of veraison. Number and total weight of clusters and berries were collected at the time of commercial harvest. Data on berry quality attributes (total soluble solids measured as °Brix, pH, titratable acidity, and some phytochemical characters) were investigated in grape samples of symptomatic and non-symptomatic vines. Descriptive analysis was realised by variance analysis and the test of Duncan.
