The rooted cutting was cultured in greenhouse for six months under five different nutrient concentrations; (a) standard, and (b) 1/2, (c) 1/5, (d) 1/10 in dilutions and (e) water. The growth of saplings was the best at (a) and poorest at (c), (d) and (e). When the saplings were placed for six months under the room temperatures of (A) 20℃, (B) 20°-25℃ and (C) 25°-30℃, the growth was better under higher temperatures. Furthermore, the experiment was undertaken in each combination of three temperatures, (A), (B) and (C), with three nutrient solutions as (a) standard concentration, (f) doubled concentration and (e) water. There was no significant difference in growth between (a) and (f) in the same temperature and between (B) and (C) in the same concentration. All of the rooted cuttings died in the open field during the winter, but many of them survived inside the cover with twofold polyvinyl film, where the lowest temperture was recorded -1℃. When the stem was cut in the fall and the stump was mulched with straw, all the sapling stumps died in spite that the temperature under the straw was +3℃. When the rooted cuttings were grown from May to November at the spacing of 0.25m×0.30m in the nursery, total dry weight of the stem was calculated to be 2.3 tons per ha.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55617","nameIdentifierScheme":"WEKO"}],"names":[{"name":"GOO, Masasi"}]},{"nameIdentifiers":[{"nameIdentifier":"55618","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KATO, Sakio"}]},{"nameIdentifiers":[{"nameIdentifier":"55619","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IKEDA, Hiroyuki"}]},{"nameIdentifiers":[{"nameIdentifier":"55620","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YAGI, Kazuhiro"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学農学部演習林樹芸研究所"},{"subitem_text_value":"東京大学農学部演習林本部"},{"subitem_text_value":"Arboricultural Research Institute in Izu, Faculty of Agriculture, University of Tokyo"},{"subitem_text_value":"Administration Office of the University Forests, Faculty of Agriculture, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"郷, 正士"}],"nameIdentifiers":[{"nameIdentifier":"55613","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"加藤, 咲夫"}],"nameIdentifiers":[{"nameIdentifier":"55614","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池田, 裕行"}],"nameIdentifiers":[{"nameIdentifier":"55615","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"八木, 和弘"}],"nameIdentifiers":[{"nameIdentifier":"55616","nameIdentifierScheme":"WEKO"}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-06-12"}],"displaytype":"detail","filename":"esrh073004.pdf","filesize":[{"value":"581.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh073004.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25611/files/esrh073004.pdf"},"version_id":"0a919829-7556-4cb6-b3e3-4dc48f043463"}]},"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":"アオサンゴの栽培","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"アオサンゴの栽培"}]},"item_type_id":"4","owner":"1","path":["2596","2595"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25611","relation_version_is_last":true,"title":["アオサンゴの栽培"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:48.952917+00:00"}
