POSTHARVEST BIOLOGY OF FRUITS

Project Details

Description

Certain polyphenolic phytochemicals in blueberry and cranberry fruit may be effective at increasing resistance to damage from fruit-rotting fungi. These fungi can cause significant reductions in both pre and post harvest fruit quality. The purpose of this study is to determine the optimum levels of each of these polyphenolic compounds extracted from blueberry and cranberry fruit that confer resistance to fruit rot infection and relate these levels to those needed for human health promotion. Once these levels are determined, through the process of dose-response, they could serve as targets levels and markers for breeding blueberries and cranberries for enhanced fungal resistance and ultimately improved health benefits and fruit quality. This could result in improved human health as a result of increased consumption of fruit. Another potential outcome could be an increase in fruit quality with reduced post-harvest decay in retail store packages if cultivars with higher levels of these phytochemicals are targeted. And it could provide updated information to growers on the most suitable fruit cultivars for postharvest quality, in combination with sensory and health benefit information.
