This project will develop models of phenology — which predict winegrape development stages for different grape varieties — to give growers the information they need to make management decisions for planting choices, watering regimes and pest and disease management.
Over the last decade, the viticulture industry has been adapting to the impacts of climate change in the Okanagan Valley by planting varieties that could not have thrived there earlier. However, winegrape producers are making these decisions with limited information about how changing climatic conditions relate to the specific needs of different varieties.
This project will build budburst-to-sugar maturity models for winegrapes for the Okanagan region and is designed to help growers adapt to climate change over both the short- and long-term. Over four years, the project will:
- Collect, clean and collate three years of researcher-collected phenological data as well as existing long-term phenological and local meteorological data from Okanagan vineyards.
- Develop phenological models for six varieties of Okanagan winegrapes.
- Test seasonal predictions of models for two years and, given accurate predictions, project models to 2100 to inform growers’ planting decisions for future decades and warmer temperatures.
