Rice seedlings were cultured in the seed packsTM containing 1/100 strength MS nutrient solution with or without 100mg/L LBP. Agronomical parameters were measured and the total root area was calculated according to the method described by Kimura (2001) after two weeks seeding. The plant age and plant height of rice seedlings were markedly enhanced by LBP treatment than those of control. The seminal root length of seedlings was also significantly (P\u003c0.05) increased by 26％ compared with that of control. In contrast, the root number per seedling was not affected by LBP treatments. Correlation between the total area of root, and the number of root or the seminal root length were not observed. It should be noted that LBP significantly (P\u003c0.05) increased the total area of root of seedlings through those of the thinner lateral root (less than 0.757 mm in diameter), not of the thicker one. These results suggest that the high recovery rate of fertilizer in co-situs application with a CAF is possible by using LBP.", "subitem_description_type": "Abstract"}]}, "item_7_full_name_3": {"attribute_name": "著者別名", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "163190", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Adachi, Yusuke"}]}, {"nameIdentifiers": [{"nameIdentifier": "163191", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Kimura, Kazuhiro"}]}, {"nameIdentifiers": [{"nameIdentifier": "163192", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Saigusa, Masahiko"}]}, {"nameIdentifiers": [{"nameIdentifier": "163193", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "Watanabe, Hajime"}]}]}, "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": "安達, 祐介"}], "nameIdentifiers": [{"nameIdentifier": "163186", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "木村, 和彦"}], "nameIdentifiers": [{"nameIdentifier": "163187", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "三枝, 正彦"}], "nameIdentifiers": [{"nameIdentifier": "163188", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "渡邊, 肇"}], "nameIdentifiers": [{"nameIdentifier": "163189", "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": "62(2)_97-103.pdf", "filesize": [{"value": "868.9 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 868900.0, "url": {"label": "62(2)_97-103.pdf", "url": "https://niigata-u.repo.nii.ac.jp/record/28369/files/62(2)_97-103.pdf"}, "version_id": "8098d9e3-be74-47b4-86ae-c4cf952089cf"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "L-β-フェニル乳酸", "subitem_subject_scheme": "Other"}, {"subitem_subject": "根表面積", "subitem_subject_scheme": "Other"}, {"subitem_subject": "植物成長調整物質", "subitem_subject_scheme": "Other"}, {"subitem_subject": "水稲", "subitem_subject_scheme": "Other"}, {"subitem_subject": "施肥効率", "subitem_subject_scheme": "Other"}, {"subitem_subject": "fertilizer recovery rate", "subitem_subject_scheme": "Other"}, {"subitem_subject": "L-β-phenyllactic acid", "subitem_subject_scheme": "Other"}, {"subitem_subject": "plant growth regulator", "subitem_subject_scheme": "Other"}, {"subitem_subject": "rice (Oryza sativa L.)", "subitem_subject_scheme": "Other"}, {"subitem_subject": "root surface area", "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": "根伸長促進物質L-β-フェニル乳酸が水稲幼植物の生育に及ぼす影響", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "根伸長促進物質L-β-フェニル乳酸が水稲幼植物の生育に及ぼす影響"}, {"subitem_title": "根伸長促進物質L-β-フェニル乳酸が水稲幼植物の生育に及ぼす影響", "subitem_title_language": "en"}]}, "item_type_id": "7", "owner": "1", "path": ["456", "1597"], "permalink_uri": "http://hdl.handle.net/10191/13105", "pubdate": {"attribute_name": "公開日", "attribute_value": "2010-07-14"}, "publish_date": "2010-07-14", "publish_status": "0", "recid": "28369", "relation": {}, "relation_version_is_last": true, "title": ["根伸長促進物質L-β-フェニル乳酸が水稲幼植物の生育に及ぼす影響"], "weko_shared_id": null}
