- Abstract
In order to improve the commerciality of Suli pear fruit, Jindingxiehua Suli pear was used as the material to study the effects of different semi‐underground ventilation storage time treatments combined with cold storage on its fruit quality during storage. The results showed that pear fruits stored in a ventilated warehouse could quickly turn yellow form green, and low temperature could effectively inhibit chlorophyll degradation. The combination of semi‐underground ventilation and cold storage could effectively improve the color of stored pear and promote the fruit peel to turn yellow from green. 20 days of semi‐underground ventilation storage treatment could maintain fruit hardness, maintain high soluble solids (TSS) content, catalase (CAT) and superoxide dismutase (SOD) activities, and inhibit the increase of polyphenol oxidase (PPO) activity. After being stored in a semi‐underground ventilated warehouse for 20 days, pears were transferred to a cold storage for 200 days, and the fruit quality and various physiological indicators showed good performance. The peel of the pears turned yellow, the decay rate (3. 3%) was the lowest, the fruit smoothness L* value (78. 5) was the highest, the TSS content (11. 8%), hardness (3. 88 kg/cm²), titrableacid (TA) content (0. 098%), and carotenoid content (29. 01 µg/g), SOD activity [354. 48 U/ (min·g)], and CAT activity [12. 97 U/ (min·g)] were lower than those of direct cold storage (CK), but the difference was not significant. PPO activity [1 621. 06 U/ (min·g)] was higher than CK and the difference was significant. The chlorophyll content in the fruit peel was significantly lower than CK. In summary, after 20 days of storage in a semi‐underground ventilated warehouse, pears should be transferred to a cold storage for medium to long‐term storage, which could meet consumer needs and maintain fruit quality comparable to cold storage. The operation was simple and convenient for application, and it could be promoted in pear producing areas
