Post-harvest UVC irradiation increases secondary metabolites in fruit of Haskap (Lonicera caerulea L.).

Post-harvest UVC irradiation has been used to increase the concentration of secondary metabolites in fruit crops. In this study we investigated the effect of post-harvest UVC irradiation on the concentration of secondary metabolites in immature, mature and over-ripe fruit of Haskap (Lonicera caerulea). Fruit were harvested from the haskap cultivar ‘Tundra’ at 16 (immature), 42 (mature) and 70 (over-ripe) days post fertilization of the flower and were subjected to 5, 10 or 20 mins of UVC irradiation. The results indicated UVC irradiation increased concentrations of quercetin, chlorogenic acid, 3,5-dicaffeoylquinic acid and the iridoid glucoside secologanin in haskap fruit after harvest. Responses of the fruit were maturity-specific, and show an interactive effect between duration of UVC irradiation and the maturity of the fruit.
