ASEV Selects 2021 Best Enology and Viticulture Papers
February 25, 2021
DAVIS, Calif., February 24, 2021…The American Society for Enology and Viticulture (ASEV) has selected the 2021 Best Paper Award winners. The authors are presented with a plaque and monetary award and will be presenting their papers during the 2021 Virtual ASEV National Conference, June 21-24. Both papers are highlighted on www.ajevonline.org and are available free of charge.
The 2021 Best Viticulture Paper, “Soil Temperature Prior to Veraison Alters Grapevine Carbon Partitioning, Xylem Sap Hormones, and Fruit Set” by Stewart K. Field of Nelson Marlborough Institute of Technology in New Zealand, Jason P. Smith and Bruno P. Holzapfel of Charles Sturt University in Australia, and Erin N. Morrison and R.J. Neil Emery of Trent University in Canada, looked into gaining a better understanding of environmental effects on grapevines and the physiological regulation of acclimation. The authors assessed the effects of soil temperature (14°C or 24°C) between bloom and veraison on growth, nonstructural carbohydrates, cytokinins, abscisic acid, and leaf function of potted Shiraz grapevines. They concluded that soil temperature significantly affects grapevine growth and that the responses are mediated largely by an influence of temperature on mobilization of reserve carbohydrates from the roots.
