In this report, change of the organic components especially Klason lignin and cutin during the decomposition of leaf litter of Japanese cedar (Cryptomeria japonica D.Don) in the Inabu forest of Nagoya University was studied. The samples in litter bag put on the forest floor were gatherd bimonthly and their organic components were analysed. When the leaf litter decomposed on the forest floor, some parts of cellulose in the amorphous region and hemicellulose of the leaf were easily degraded in the early periods of the biodegradation. After that, residual hemicellulose was relatively stabilised. Cellulose, on the other hand, seemed to be gradually degraded and remained a region of the higher crystallinity index at the final period. Klason lignin in the litter increased with the progress of biodegradation. However, the value of the Klason lignin did not represent that of the true lignin in the litter. It seemed that the Klason lignin might contain cutin, humic substance, protein, and nucreic acid in various ratios at each period. Cutin seemed to be easily degradable by soil microorganisms, it decreased to one half for 14months of biodegradation on the forest floor. In constitutent monomers of the cutin, 10 (9), 16-dihydroxyhexadecanoic aid was easily decomposed, while almost 16-hydroxyhexadcanoic acid was remained in the litter for 14months of biodegradation. In the final period of biodebradation, it seemed that humic substance was produced considerably in the litter.", "subitem_description_language": "en", "subitem_description_type": "Abstract"}]}, "item_9_description_5": {"attribute_name": "内容記述", "attribute_value_mlt": [{"subitem_description": "農林水産研究情報センターで作成したPDFファイルを使用している。", "subitem_description_language": "ja", "subitem_description_type": "Other"}]}, "item_9_identifier_60": {"attribute_name": "URI", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/2237/8666"}]}, "item_9_identifier_registration": {"attribute_name": "ID登録", "attribute_value_mlt": [{"subitem_identifier_reg_text": "10.18999/bulnuf.9.44", "subitem_identifier_reg_type": "JaLC"}]}, "item_9_publisher_32": {"attribute_name": "出版者", "attribute_value_mlt": [{"subitem_publisher": "名古屋大学農学部付属演習林", "subitem_publisher_language": "ja"}]}, "item_9_relation_43": {"attribute_name": "関連情報", "attribute_value_mlt": [{"subitem_relation_type": "isVersionOf", "subitem_relation_type_id": {"subitem_relation_type_id_text": "http://rms1.agsearch.agropedia.affrc.go.jp/contents/JASI/pdf/academy/40-2644.pdf", "subitem_relation_type_select": "URI"}}]}, "item_9_select_15": {"attribute_name": "著者版フラグ", "attribute_value_mlt": [{"subitem_select_item": "publisher"}]}, "item_9_source_id_7": {"attribute_name": "ISSN（print）", "attribute_value_mlt": [{"subitem_source_identifier": "0469-4708", "subitem_source_identifier_type": "PISSN"}]}, "item_9_text_14": {"attribute_name": "フォーマット", "attribute_value_mlt": [{"subitem_text_value": "application/pdf"}]}, "item_access_right": {"attribute_name": "アクセス権", "attribute_value_mlt": [{"subitem_access_right": "open access", "subitem_access_right_uri": "http://purl.org/coar/access_right/c_abf2"}]}, "item_creator": {"attribute_name": "著者", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "川上, 日出國", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "18777", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KAWAKAMI, Hidekuni", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "18778", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "草島, すなお", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "18779", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KUSAJIMA, Sunao", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "18780", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "沓名, 重明", "creatorNameLang": "ja"}], "nameIdentifiers": [{"nameIdentifier": "18781", "nameIdentifierScheme": "WEKO"}]}, {"creatorNames": [{"creatorName": "KUTSUNA, Sigeaki", "creatorNameLang": "en"}], "nameIdentifiers": [{"nameIdentifier": "18782", "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": "2018-02-19"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "bulnuf_9_44.pdf", "filesize": [{"value": "801.3 kB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_note", "mimetype": "application/pdf", "size": 801300.0, "url": {"label": "bulnuf_9_44.pdf", "objectType": "fulltext", "url": "https://nagoya.repo.nii.ac.jp/record/6995/files/bulnuf_9_44.pdf"}, "version_id": "25a9083e-0d59-448d-a72a-6fd0d271009d"}]}, "item_keyword": {"attribute_name": "キーワード", "attribute_value_mlt": [{"subitem_subject": "Leaf litter", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Klason lignin", "subitem_subject_scheme": "Other"}, {"subitem_subject": "Cutin", "subitem_subject_scheme": "Other"}, {"subitem_subject": "10,16-Dihydroxyhexadecanoic acid", "subitem_subject_scheme": "Other"}, {"subitem_subject": "16-Hydroxyhexadecanoic acid", "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": "スギ落葉有機組成分特にクチンの生分解について", "item_titles": {"attribute_name": "タイトル", "attribute_value_mlt": [{"subitem_title": "スギ落葉有機組成分特にクチンの生分解について", "subitem_title_language": "ja"}]}, "item_type_id": "9", "owner": "1", "path": ["864"], "permalink_uri": "https://doi.org/10.18999/bulnuf.9.44", "pubdate": {"attribute_name": "PubDate", "attribute_value": "2007-08-16"}, "publish_date": "2007-08-16", "publish_status": "0", "recid": "6995", "relation": {}, "relation_version_is_last": true, "title": ["スギ落葉有機組成分特にクチンの生分解について"], "weko_shared_id": -1}
