About the research project

Strawberry (Fragaria spp.) is an important horticultural crop worldwide and a model system for understanding non-climactic fruit ripening. Strawberry varieties grown in Tasmania have been bred to thrive in cool climates. However, even Tasmania experiences hot summers and these higher temperatures can have detrimental effects on fruit ripening and resulting fruit quality.

The factors controlling the impact of high temperatures on strawberry fruit ripening are not well understood, so adaptive management practices have not yet been developed. In this project we will investigate the biochemical, molecular, and ecophysiological factors affecting strawberry fruit ripening under hot temperature conditions and explore novel approaches to mitigate these factors, thereby improving strawberry fruit quality and marketability under these conditions. Specifically, we will be addressing two pressing grower issues: fruit size (too small in hot weather) and fruit quality (can turn soft in hot weather). We will determine a) the role of plant growth regulators (phytohormones) in strawberry ripening, b) which genes and proteins are involved in regulating fruit ripening and quality and c) management strategies that could be applied to improve fruit quality under hot temperatures. Management strategies will be tested in controlled field trials. Our experiments will allow us to determine which genes could be targeted for manipulation and we will make this information available to the strawberry breeding industry to aid in the development of heat tolerant strawberry cultivars that still perform well in the cool Tasmanian conditions.

This project has been co-designed with Berried In Tas and Pinata Farms. Where relevant, this project will be implemented on commercial farms, the Forthside Vegetable Research Facility and in glasshouse facilities offsite.
