- Abstract
- The popularity and demand of early season ‘Wonhwang’ pear fruit are getting increased due to premium fruit quality. However, numerous physiological disorders can be developed after harvest and during short-term storage. The objective of the study was aimed to evaluate the effectiveness of gibberellic acid4+7 (GA4+7) at fruitlet stage, 1-methylcylcopropene (1-MCP), pre-conditioning, or 1-MCP + pre-conditioning on fruit quality attributes and incidence of physiological disorders in ‘Wonhwang’ pears stored at commercial storage facility and then shipped to Taiwan from South Korea. GA4+7 treatment reduced fresh weight loss but was lowered flesh firmness compared with the other treatments. 1-MCP treatment maintained superior fruit firmness during shelf life relative to other treatments. Soluble solids concentration (SSC) did not differ among treatments. Titratable acidity (TA) was lowest in GA4+7 treatment but relatively retained in 1-MCP treatment, compared with the other treatments. Lightness (L*) was not affected by treatments among tissues during shelf life but was higher in 1-MCP treatment than in pre-conditioning or GA4+7 treatments. Peel staining was only detected in GA4+7 treated fruit. 1-MCP treatment reduced the severity of flesh browning, core browning, water soaking and cavity, compared with the other treatments. Overall, the results suggested that 1-MCP treatment to early season ‘Wonhwang’ Asian pears enables the retention of fruit firmness and reduces the severity of physiological disorders for international trading, compared with GA4+7 or pre-conditioning treatments. © 2019 Elsevier B.V.
