Abstract: The kiwifruit has long been called ‘the king of fruits’ because of its remarkably high vitamin C content and balanced nutritional composition of minerals,dietary fiber,and other health-beneficial metabolites.Kiwifruit is a climacteric fruit and easily decays after harvest Hence,how to extend the storage life of kiwifruit is a current challenge for the rapid development of the kiwifruit industry.Postharvest physiological changes in kiwifruit have a strong impact on storage life and fruit quality,in particular,changes in respiration,ethylene biosynthesis,signal transduction,and fruit softening.These physiologies are also closely related to the development and application of preservation technology in kiwifruit.Therefore,in this review,studies on postharvest respiration,ethylene biosynthesis,signal transduction,and fruit softening of the kiwifruit were reviewed,and their effects on fruit storability and preservation technology were discussed.This study aims to provide theoretical guidelines for the breeding of new kiwifruit cultivars with high storability and for the development of kiwifruit preservation technology.
