The Proper Harvest Time and Storage Regime of 'Manpungbae' Pear Cultivated in Korea

摘要

The present study was conducted to establish the proper harvest time of thi Asian pear 'Manpungbae' through the changes in fruit quality at maturity anc during storage. The peel of 'Manpungbae' fruit turned yellow, fruit increased ii soluble solids concentration (SSC) as the harvest was delayed, however, firmnesi decreased and mealiness appeared after 170 days after full bloom (DAFB). The SSC increased but firmness did not change significantly during storage. Fruit SSC increased during storage of 5 weeks and fruit firmness decreased, however, th< firmness remained higher than 12 N (N/5 mm o) irrespective of harvest maturity Considering fruit quality after storage, the proper harvest time was from 160 unti 167 DAFB. The larger fruit (850 g) had a tendency to be higher in SSC than smallei fruit (550 g) at harvest and after storage. There was no difference in firmnes! between the larger and smaller fruit before storage. The firmness of smaller fruil did not change during storage, but for larger fruitit decreased by about 2.1 N.
