Changes in physicochemical characteristics during fruit development in June-bearing strawberry cultivars

Changes in physicochemical characteristics were investigated during fruit development in 'Maehyang', 'Seolhyang', 'Keumhyang', 'Akihime', and 'Red Pearl' strawberries. Fresh weights and color parameters of strawberry fruits changed significantly during the fruit development in all cultivars. Fruit shapes of 'Maehyang' and 'Akihime' were conical, with an index of length to width being 1.5 and that of 'Seolhyang', 'Keumhyang', and 'Red Pearl' were cordate, the index being 1.3. Firmness decreased as the fruit developed in all cultivars. Contents of sugars, organic acids, ascorbic acid, and anthocyanin increased as the fruits developed while the ellagic acid content decreased. Sugars, ascorbic acid, and anthocyanin contents of 'Maehyang', 'Seolhyang', and 'Keumhyang' were higher than those of 'Akihime' and 'Red Pearl'. Results indicate that newly-bred Korean strawberry cultivars containing high levels of bioactive compounds were superior to major Japanese cultivars that have been broadly cultivated in East Asian countries.This work was carried out with the support of Cooperative Research Program for Agriculture Science & Technology Development (Project No. 907002082012)Rural Development Administration, Republic of Korea.OAIID:oai:osos.snu.ac.kr:snu2013-01/102/0000027607/1SEQ:1PERF_CD:SNU2013-01EVAL_ITEM_CD:102USER_ID:0000027607ADJUST_YN:YEMP_ID:A075898DEPT_CD:517CITE_RATE:0FILENAME:2013-2-heb-발달단계별딸기특성-김성겸.pdfDEPT_NM:식물생산과학부EMAIL:changhoo@snu.ac.krSCOPUS_YN:NCONFIRM:
