In commercial markets in Korea, the recommended storage period of hardy kiwifruits is one to 2 weeks and an additional 2 or 3 days for shelf life. The main reasons for the short storage life are fruit softening, skin wrinkling due to water loss (dryness) and fruit decay. Fruit softening rapidly increases at the room-temperature ripening period, after harvest or cold storage (Krupa et al., 2011). Unlike A. deliciosa, the hardy kiwifruits are very sensitive to dryness because of their smooth peels that lack hair. This phenotype characteristic is the main reason for the short-storage time and fast loss of postharvest quality (Strik, 2005).
