For the experiment, two genotypes of E. arundinaceus, JW4 and JW630, were obtained from the NIAS gene bank. The dry weights of shoots and roots of both genotypes were highest when N was supplied as NH4+NO3, but the difference in growth between plants grown with NH4+NO3 and those with NH4 or NO3 was greater for JW630 than for JW4. Plants supplied with NH4 alone had scorched leaves and those supplied with NO3 alone had pale colored leaves, but N form did not significantly affect the total N concentration of either shoots or roots of both genotypes. The NO3-N concentration of shoots and roots was highest in the NO3 treatment and higher in JW4 than in JW630. The NO3-N concentration of shoots of JW4 supplied with NO3 alone was 0.25% g–1 dry weight, but only a trace of NO3-N was present in shoots and roots of both genotypes when supplied with NH4 alone. The NO3-N concentration of both shoots and roots in plants supplied with NH4+NO3 was a fraction of that found in plants supplied with NO3 alone. In conclusion, the results suggest that the best form for supplying N to Erianthus arundinaceus during the initial 4 months of growth is NH4+NO3, and that a high level of NO3 will accumulate in plant tissue if NO3 alone is applied.","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.24514/00000072","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_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2432-7867","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":"高溝, 正"},{"creatorName":"タカミゾ, タダシ","creatorNameLang":"ja-Kana"},{"creatorName":"TAKAMIZO, Tadashi","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"安藤, 象太郎"},{"creatorName":"アンドウ, ショウタロウ","creatorNameLang":"ja-Kana"},{"creatorName":"ANDO, Shotaro","creatorNameLang":"en"}],"nameIdentifiers":[{},{},{}]},{"creatorNames":[{"creatorName":"小林, 真"},{"creatorName":"コバヤシ, マコト","creatorNameLang":"ja-Kana"},{"creatorName":"KOBAYASHI, Makoto","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":"2017-08-23"}],"displaytype":"detail","filename":"nilgs_report17-4.pdf","filesize":[{"value":"727.1 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"nilgs_report17-4.pdf","url":"https://repository.naro.go.jp/record/83/files/nilgs_report17-4.pdf"},"version_id":"d90c1532-5fc7-4aca-81fb-b997b686c9df"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"エリアンサス","subitem_subject_scheme":"Other"},{"subitem_subject":"Erianthus arundinaceus","subitem_subject_scheme":"Other"},{"subitem_subject":"窒素源","subitem_subject_scheme":"Other"},{"subitem_subject":"砂耕","subitem_subject_scheme":"Other"},{"subitem_subject":"硝酸態窒素","subitem_subject_scheme":"Other"},{"subitem_subject":"Erianthus arundinaceus","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"N form, sand culture","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"nitrate","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":"砂耕培養液中の窒素源の形態がエリアンサス（Erianthus arundinaceus）の 生育に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"砂耕培養液中の窒素源の形態がエリアンサス（Erianthus arundinaceus）の 生育に及ぼす影響"},{"subitem_title":"Growth Response of Erianthus arundinaceus Grown in Sand Culture to the Form of N Supplied in Nutrient Solution","subitem_title_language":"en"}]},"item_type_id":"10002","owner":"11","path":["29","42"],"pubdate":{"attribute_name":"公開日","attribute_value":"2017-08-23"},"publish_date":"2017-08-23","publish_status":"0","recid":"83","relation_version_is_last":true,"title":["砂耕培養液中の窒素源の形態がエリアンサス（Erianthus arundinaceus）の 生育に及ぼす影響"],"weko_creator_id":"11","weko_shared_id":-1},"updated":"2023-05-15T16:12:12.501366+00:00"}
