The Incidence of Neofabraea spp. in 'Pinova' Apples Can be Reduced at Elevated Storage Temperatures

摘要

'Pinova' apples are highly susceptible to Neofabraea fungal storage rots. Experiments at the Competence Centre for Fruit Growing at Lake Constance (KOB) with dynamic controlled atmosphere storage (CA) have consistently shown lower rot incidence when 'Pinova' fruit are stored under higher temperatures (3 °C) compared to storage under ultra low oxygen (ULO) at 1 °C. DCA is storage technology that can be used for organic fruit. Increased storage temperatures had no negative effects on fruit firmness (FF). 'Pinova' is a slow softening cultivar and FF at the recommended storage temperature of 1 °C did not differ from fruit stored at 3 °C. Increased storage temperatures with DCA may help reduce the incidence of Neofabraea spp. storage rots in 'Pinova' while still maintaining acceptable fruit quality. Increased storage temperatures can also provide energy savings.
