Influence of Picking Stage and Storage Type on the Fruit Respiration Change and Panel Test in 'Wonhwang', 'Hwasan', and 'Mansoo' Pear

摘要

Three kinds of Asian pear fruits were harvest at conventional ripening stage and several days earlier than ripening ones including 'Wonhwang', 'Hwasan' and 'Mansoo' represented the early-season, mid-season, and late-season mature cultivars, respectively. In the ambient temperature storage, respiratory pattern of 'Wonhwang' cultivar showed some climacteric, but 'Hwasan' and 'Mansoo' showed non-climacteric, So, the controlled atmosphere (CA) effect was not clear in 'Hwasan' and 'Mansoo'. The fruit firmness of 'Wonhwang' pear was well-maintained in CA storage compared with low temperature storage. According to the fruit firmness, incidence of core breakdown, and value of sensory test, the proper storage periods of 'Wonhwang' pear was 15-20 days in ambient temperature, 120 days in low temperature, and 160 days in CA storage. And marketable quality was kept properly for 20-30 days in ambient, 120 - 160 days in low temperature, and 160-180 days in CA storage of 'Hwasan' pear. Storage periods was longerin 'Mansoo' fruit that 'Hwasan' pear stored at ambient temperature. But in low temperature storage, the proper storage periods was about the same as 'Hwasan' pear. The storage periods of 'Mansoo' pear was 200 days in CA storage.
