This project will develop phenology models, from budburst-to-sugar maturity, for six wine grape varieties in the Okanagan region to provide improved information for variety selection and management.
The viticulture industry has already been adapting to the changes in climate in the Okanagan Valley by planting varieties that could not have thrived there previously. However, phenology models have not been developed for any wine grape varieties in Canada, making this project the first of its kind, provincially and nationally.
In the short term, the phenology models can provide predictions of plant development for each season, information that can be used in conjunction with other decision support tools or weather data to allow for crop adjustments, more accurate watering regimes and improved management of pests and diseases.
In the longer term, phenological models can help guide planting decisions through information on how projections for changing climatic conditions relate to the specific needs of different varieties.
Over four years, the project will:
- Gather, clean and collate three years of researcher-collected phenological data as well as existing long-term phenological and meteorological data from Okanagan vineyards.
- Develop phenological models for six varieties of Okanagan wine grapes: three white (Chardonnay, Riesling, Sauvignon Blanc) and three red (Merlot, Pinot Noir, Syrah).
- Test accuracy of seasonal predictions of models for two years, and then apply models to 2100 to enable consideration of future conditions in variety selection.
Once complete, the phenological models, project results and fact sheets will be made publicly available.
