It causes fruit sugar at harvest to be generally lower than that from healthy vines. This difference is not apparent in early summer. In unirrigated vineyards yields are about one third of those of healthy vines. Wood production is also reduced, and fruit clusters are fewer and smaller.}, issn = {0002-9254}, URL = {https://www.ajevonline.org/content/10/4/173}, eprint = {https://www.ajevonline.org/content/10/4/173.full.pdf}, journal = {American Journal of Enology and Viticulture} }
