The electrodes equipped with iron and zinc or iron were soaked in the culture solution and voltage\\nand plants (spinach) growth were investigated. One pair of Fe-Zn (each volume; 15×45×1.0 mm) electrode made 0.35V during first several hours, then the voltage was gradually decreased and finally reached 0.2 V after ２ days.Two days after culture with chemical battery with Fe-Zn, Zn2+ concentration in culture medium was increased and Zn was highly accumulated in both shoots and roots. The dry weight of plants equipped without electrodes.\\nThis might be caused by excess Zn2+. Using the Fe-Mg as electrodes made 1.0V at first several hours, and then the voltage was also decreased and finally reached 0.5V. However, any excess symptom on plant, mineral concentration change in plant and dry weight differences between normal and chemical battery application were\\nnot observed when using Mg as electrode. In conclusion to make chemical battery equipped with hydroponically plant culture it was recommended to use electrode as Fe-Mg pair from the point of view of both plant nutrition\\nand electromotive force.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "162346", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ohtake, Norikuni"}]}, {"nameIdentifiers": [{"nameIdentifier": "162347", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ito, Saori"}]}, {"nameIdentifiers": [{"nameIdentifier": "162348", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Goto, Daiki"}]}, {"nameIdentifiers": [{"nameIdentifier": "162349", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ono, Tomoki"}]}, {"nameIdentifiers": [{"nameIdentifier": "162350", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Sueyoshi, Kuni"}]}, {"nameIdentifiers": [{"nameIdentifier": "52", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Ohyama, Takuji"}]}]}, "item_7_publisher_7": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "新潟大学農学部"}]}, "item_7_select_19": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_7_source_id_11": {"attribute_name": "書誌レコードID", "attribute_value_mlt": [{"subitem_source_identifier": "AN00183393", "subitem_source_identifier_type": "NCID"}]}, "item_7_source_id_9": {"attribute_name": "ISSN", "attribute_value_mlt": [{"subitem_source_identifier": "03858634", "subitem_source_identifier_type": "ISSN"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "大竹, 憲邦"}], "nameIdentifiers": [{"nameIdentifier": "162340", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "伊藤, 紗織"}], "nameIdentifiers": [{"nameIdentifier": "162341", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "後藤, 大輝"}], "nameIdentifiers": [{"nameIdentifier": "162342", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "小野, 雄基"}], "nameIdentifiers": [{"nameIdentifier": "162343", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "末吉, 邦"}], "nameIdentifiers": [{"nameIdentifier": "162344", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "大山, 卓爾"}], "nameIdentifiers": [{"nameIdentifier": "52", "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": "2019-08-20"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "69_49-55.pdf", "filesize": [{"value": "1.9 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1900000.0, "url": {"label": "69_49-55.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28262/files/69_49-55.pdf"}, "version_id": "4dbc9cc2-5c46-4be6-a3b4-7dfe71efd9f2"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "水耕栽培", "subitem_subject_scheme": "Other"}, {"subitem_subject": "化学電池", "subitem_subject_scheme": "Other"}, {"subitem_subject": "マグネシウム", "subitem_subject_scheme": "Other"}, {"subitem_subject": "培養培地", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Hydroponic culture", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Chemical battery", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Magnesium", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Mineral nutrient", "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": "植物水耕培養液を活用した化学電池の電極の調査", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "植物水耕培養液を活用した化学電池の電極の調査"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1585"], "permalink_uri": "http://hdl.handle.net/10191/47177", "pubdate": {"attribute_name": "公開日", "attribute_value": "2017-03-23"}, "publish_date": "2017-03-23", "publish_status": "0", "recid": "28262", "relation": {}, "relation_version_is_last": true, "title": ["植物水耕培養液を活用した化学電池の電極の調査"], "weko_shared_id": 2}
