Nitrate content in the edible part was measured for nine leaf lettuce cultivars, and L-120 was selected as a low-nitrate cultivar because the nitrate content of this cultivar was 2590mg kg-1FW. As a vacuolar osmoticum, a decrease in nitrate content was compensated by an increase in the sum of contents of organic acids, sugars, and chloride, and this value of L-120 was significantly higher than those of the other eight cultivars. In the root system of leaf lettuce plants, roots of 1mm or less in diameter (fine roots) played a role in the absorbing function using the pipe model concept, and the volume of fine roots of L-120 was significantly smaller than those of the normal- nitrate cultivar no tip. L-120 exhibited a significantly lower net nitrate uptake than no tip during the growing period. No significant difference in nitrate assimilation rate was found between L-120 and no tip. These results suggest that the low-nitrate cultivar L-120 limits the root uptake of nitrate compared with no tip, and the limitation of nitrate uptake is caused in part by the small volume of fine roots.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00000229","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":"10.24514/00000229","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":"岡本, 章秀"},{"creatorName":"オカモト, アキヒデ","creatorNameLang":"ja-Kana"},{"creatorName":"OKAMOTO, Akihide","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"北﨑, 一義"},{"creatorName":"キタザキ, カズヨシ","creatorNameLang":"ja-Kana"},{"creatorName":"KITAZAKI, Kazuyoshi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"大和, 陽一"},{"creatorName":"ヤマト, ヨウイチ","creatorNameLang":"ja-Kana"},{"creatorName":"YAMATO, Yoichi","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":"NARO_ko_67_003p.pdf","filesize":[{"value":"770.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"NARO_ko_67_003p.pdf","url":"https://repository.naro.go.jp/record/249/files/NARO_ko_67_003p.pdf"},"version_id":"d7c45268-52e1-477d-b4f9-90a8209a1a7c"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"細根，品種間差，水耕，硝酸蓄積，硝酸吸収，浸透圧調整物質","subitem_subject_scheme":"Other"},{"subitem_subject":"Fine root, Genetic variation, Hydroponic, Nitrate accumulation, Nitrate uptake, Osmoticum","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":"完全人工光型植物工場で栽培するリーフレタスにおける低硝酸品種の選定および低硝酸品種の根部特性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"完全人工光型植物工場で栽培するリーフレタスにおける低硝酸品種の選定および低硝酸品種の根部特性"},{"subitem_title":"Screening Cultivars for Low Nitrate Content and Root Characteristics of Low-Nitrate Cultivars of Leaf Lettuce Grown in a Closed Plant  Factory","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":"249","relation_version_is_last":true,"title":["完全人工光型植物工場で栽培するリーフレタスにおける低硝酸品種の選定および低硝酸品種の根部特性"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-05-15T15:19:28.363015+00:00"}
