In some areas in Brazil,\u3000sugarcane has been grown continually over very long periods without N fertiliser inputs.\u3000Therefore, the occurrence of N fixation has been suspected. However, quantitative studies\u3000seeking to identify the N2 fixation sites in the plant and to record the translocation of fixed N\u3000around the plant have not yet established. A 15N2 gas tracer experiment was conducted using\u3000young sugarcane plants to investigate the sites of N2 fixation and also to explore the possibility\u3000of translocation of the fixed N among the plant\u2019s major organs. Young sugarcane plants\u3000(Saccharum officinarum L.) about 40 cm high and some 14 days after sprouting from a stem\u3000cutting were exposed to 15N2 labeled air in a 500 mL plastic cylinder for 7 days. Following the\u30007-day 15N2 feeding, some plants were potted and grown on in normal air for a further chase\u3000period. The incorporation of 15N into the shoot, roots, and stem cutting was analysed at day-3,\u3000and day-7 of the labeling period and at day-14, and day-21 during the chase period. After 3 days\u3000of 15N2 feeding, the % of N derived from the 15N labeled air in the shoot, roots and stem cutting\u3000were 0.027%, 2.22 % and 0.271 %, respectively. The roots showed the highest N fixing activity\u3000followed by the stem cutting, while the incorporation of 15N into the shoot was very low. After\u300021 days about a half of the N originating in the stem cutting had been transported to the shoot\u3000and the roots. However, the 15N fixed either in the roots or in the stem cutting remained in the\u3000original parts and was not appreciably transported to the shoot.", "subitem_description_type": "Abstract"}]}, "item_5_publisher_7": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Nature Publishing Group"}]}, "item_5_select_19": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Ohyama, Takuji"}], "nameIdentifiers": [{"nameIdentifier": "52", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Momose, Atsushi"}], "nameIdentifiers": [{"nameIdentifier": "7388", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Ohtake, Norikuni"}], "nameIdentifiers": [{"nameIdentifier": "7389", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sueyoshi, Kuni"}], "nameIdentifiers": [{"nameIdentifier": "7390", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Sato, Takashi"}], "nameIdentifiers": [{"nameIdentifier": "7391", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Nakanishi, Yasuhiro"}], "nameIdentifiers": [{"nameIdentifier": "7392", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "Akao, Shoichiro"}], "nameIdentifiers": [{"nameIdentifier": "7393", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2019-07-29"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "npre20082360-1.pdf", "filesize": [{"value": "7.7 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 7700000.0, "url": {"label": "npre20082360-1.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/2172/files/npre20082360-1.pdf"}, "version_id": "db9ce822-8006-4741-b391-2f541f6da8d9"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Nitrogen Fixation and Translocation in Sugarcane", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Nitrogen Fixation and Translocation in Sugarcane"}, {"subitem_title": "Nitrogen Fixation and Translocation in Sugarcane", "subitem_title_language": "en"}]}, "item_type_id": "5", "owner": "1", "path": ["453/454", "485/486/487"], "permalink_uri": "http://hdl.handle.net/10191/23763", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2013-10-10"}, "publish_date": "2013-10-10", "publish_status": "0", "recid": "2172", "relation": {}, "relation_version_is_last": true, "title": ["Nitrogen Fixation and Translocation in Sugarcane"], "weko_shared_id": null}
