Responses of Vitis vinifera ‘Pinot gris’ Grapevines to Exogenous Abscisic Acid (ABA): I. Yield, Fruit Quality, Dormancy, and Freezing Tolerance

Abstract

Economic losses due to cold weather events are a major constraint to the expansion of premium but cold-sensitive winegrape cultivars in colder regions, such as Ohio (USDA) Plant Hardiness Zones 6b–5b (−17.8 to −26.1 °C) (ARS-USDA 2012). The purpose of this study was to determine whether a foliar application of abscisic acid (ABA) could increase the freezing… (More)
