With funding from the Growing Forward 2 (OMAFRA) we are worked with the University of Guelph out of the Simcoe Research Station on this project to investigate frost tolerance of two grape cultivars in Southern Ontario. This is a multi-year project which began in May of 2012 and ended July of 2016.
The long-term benefits of this project include the provision of rootstock for current and new growers of grapes in Ontario, and will have additional specific benefits for growers in the sand plains. This assists with the diversification of agricultural operations in the former tobacco growing region. It is expected that rootstock will make the growers much more competitive, have the ability to have cold tolerant varieties and provide specific rootstock for the Ontario region.
Summary of Findings:
- Vitis riparia is more prevalent is more prevalent than Vitis syrticola in southwestern Ontario.
- There is a greater percentage of male plants compared to female plants because a lack of fruiting allows for increased winter survival. However, female plants survive winter well and may have more resistance to pests.
- There is a greater percentage of glabrous petioles than pubescent petioles in the area, which may affect the winter survival of the plants.
