Therefore, we evaluated cultivar variations and differences in the way they respond to storage time and harvest period, as well as relationships with other traits, to obtain basic knowledge of the apparent modulus of elasticity of strawberries. The apparent modulus decreased during six days of storage at 15°C, and the extent of decrease differed among cultivars. Similarly, the apparent modulus of elasticity decreased over the harvest period, from February to April, and the extent of decrease again differed among cultivars. The apparent modulus of elasticity seems to be a good index of storage quality because it changes in a manner that is sometimes easier to discern than fruit firmness. However, neither the apparent modulus of elasticity nor fruit firmness differed among any cultivars observed after April. Furthermore, among the 48 cultivars studied, the apparent modulus of elasticity was higher in the Suzuakane and Morioka No. 24 cultivars than in Kurume No. 16. In addition, the apparent modulus of elasticity was an accurate predictor of fruit skin toughness 83.9% of the time. The present study confirmed that the apparent modulus of elasticity is more appropriate for evaluating storage quality even when it is substituted by fruit firmness to some extent. Our data suggested that the use of the apparent modulus of elasticity is recommended except for late spring.","subitem_description_type":"Abstract"}]},"item_10002_description_6":{"attribute_name":"内容記述","attribute_value_mlt":[{"subitem_description":"2018.4.24 誤植の修正(p1. タイトルの\"1)\"を削除)","subitem_description_type":"Other"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00000227","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"国立研究開発法人 農業・食品産業技術総合研究機構"},{"subitem_publisher":"National Agriculture and Food Research Organization (NARO)"}]},"item_10002_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type":"isIdenticalTo","subitem_relation_type_id":{"subitem_relation_type_id_text":"10.24514/00000227","subitem_relation_type_select":"DOI"}}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2432-8103","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"遠藤（飛川）, みのり"},{"creatorName":"エンドウ（ヒカワ）, ミノリ","creatorNameLang":"ja-Kana"},{"creatorName":"HIKAWA-ENDO, Minori","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"曽根, 一純"},{"creatorName":"ソネ, カズヨシ","creatorNameLang":"ja-Kana"},{"creatorName":"SONE, Kazuyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"藤田, 敏郎"},{"creatorName":"フジタ, トシロウ","creatorNameLang":"ja-Kana"},{"creatorName":"FUJITA, Toshiro","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"森下, 昌三"},{"creatorName":"モリシタ, マサミ","creatorNameLang":"ja-Kana"},{"creatorName":"MORISHITA, Masami","creatorNameLang":"en"}],"nameIdentifiers":[{},{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2018-03-27"}],"displaytype":"detail","filename":"67－001v2.pdf","filesize":[{"value":"533.5 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NARO_ko_67_001p.pdf","url":"https://repository.naro.go.jp/record/247/files/67－001v2.pdf"},"version_id":"e92455b6-8b59-45ee-8796-de9159d71bf6"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"イチゴ，果実硬度，貫入変形量，日持ち性，見かけ弾性率","subitem_subject_scheme":"Other"},{"subitem_subject":"Strawberry, Fruit firmness, Compression depth, Storage quality, Apparent modulus of elasticity","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"jpn"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"departmental bulletin paper","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"イチゴ果実における見かけ弾性率の貯蔵，収穫時期による変化および遺伝資源評価","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"イチゴ果実における見かけ弾性率の貯蔵，収穫時期による変化および遺伝資源評価"},{"subitem_title":"Changes in the Apparent Modulus of Elasticity of Strawberries During Storage and Harvest Periods, and Evaluation of the Apparent Modulus of Elasticity in Different Strawberry  Cultivars","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"11","path":["39","81"],"pubdate":{"attribute_name":"公開日","attribute_value":"2018-03-27"},"publish_date":"2018-03-27","publish_status":"0","recid":"247","relation_version_is_last":true,"title":["イチゴ果実における見かけ弾性率の貯蔵，収穫時期による変化および遺伝資源評価"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-05-15T23:16:05.577793+00:00"}
