Grape bud hardiness reports for BC, Early December 2019
Cold weather remains an ongoing challenge for the grape and wine industry across Canada. While climate change is predicted to expand areas suitable for wine grape production in the country, more frequent extreme cold weather events through the year, including cold episodes lethal to grapevines are also predicted. Activities 5, 6 & 7 will explore methods to reduce crop loss risks by increasing vineyard tolerance to extreme cold events through enhanced hardiness, crop protection technologies and improved cultivar selection.
CCOVI partnered with two commercial grape growers to plant the St. Catharines and Niagara-on-the-Lake vineyards that are being used for a clone and rootstock evaluation program of the main VQA grapevine varieties in Ontario.
Winter Grape Bud Hardiness results for Early April. The hardiness levels were determined as average lethal temperature exotherms (LTE) measured on buds of several varieties by region collected on April 9th and 10th in the Okanagan Valley.
