Following these low temperatures a critical examination of buds, arms, and trunks showed that out of 88 European varieties 39 had little or no injury; out of 34 American varieties 17 showed no injury; and of 14 French hybrids there were 11 that were not appreciably affected.}, issn = {0002-9254}, URL = {https://www.ajevonline.org/content/25/1/24}, eprint = {https://www.ajevonline.org/content/25/1/24.full.pdf}, journal = {American Journal of Enology and Viticulture} }
