Abstract: Pear is a major global fruit commodity, with the majority of pears being stored for an extended period after harvest to meet market demand. Therefore, post-harvest storage and transportation play crucial roles in maintaining the quality and value of pear fruits, as well as ensuring the sustainable development of the industry.However, one common issue that arises after harvesting is black skin disease on the surface of pear peel. This physiological disease often occurs during late storage or shelf life after leaving the warehouse, resulting in irregular black-brown spots on the fruit's appearance. While it does not affect the flesh consumption, it significantly reduces the commercial value of the fruit and leads to substantial economic losses.Due to its complex causes and lack of effective preservation measures, black skin disease has become a pressing problem that needs to be addressed in post-harvest storage and transportation of pear fruits.This paper elaborates on possible mechanisms behind black skin disease occurrence in pears after harvest and analyzes how factors such as origin, maturity, and storage environment impact its incidence. Additionally, it discusses preservation measures for preventing and controlling black skin disease occurrence in pears including temperature regulation, gas regulation, and hormone regulation.Finally, suggestions are made for further research on pear fruit black skin disease to provide reference for theoretical research and technological development in post-harvest storage and transportation of pear fruits.
