Abstract
This study was conducted on how the harvest time affect fruit quality, core breakdown, and taste of GA-pasted 'Wonhwang' pear (Pyrus pyrifolia Nakai) fruit in order to verify the optimum harvest time. Harvest time included 110, 115, 120, 125, 130 days after full bloom (DAFB). Delayed fruit harvest increased fruit weight and content of soluble solids but decreased firmness, titratable acidity, and starch content. Harvest at 130 DAFB severely reduced fruit firmness and increased fruit core breakdown for 21 days at room storage, while harvest at 115 DAFB showed the opposite result of the fruit firmness and breakdown. Delayed fruit harvest reduced fruit taste, regardless of GA pasting on fruit. GA-pasted fruit showed reduced taste in advance compared to those of non GA-pasted fruit, regardless of the harvest time. Harvest at 120 DAFB would be suitable to maintain fruit quality and reduce core breakdown.
