In total, 101 trees from 18 sites and 76 trees from 15 sites (stand age: 5-33 years) were harvested to estimate above-ground biomass (stems, branches, leaves), and below-ground biomass. The coefficients of correlation for the obtained allometric relationships between tree DBH and stem, branch, and aboveground biomass showed high values, ranging from 0.94 to 0.99 at each site. DBH also had a high correlation with below-ground biomass (R2=0.90). Similar wood density of the sampled trees might have reduced site-specific differences. The present results indicated that stem, branch, above-ground biomass, and below-ground biomass might be estimated from our allometric equations with DBH data even when collected from site with different index values, and climatic conditions. Stand-level carbon stock amount was estimated using the present equations. Above-ground and below-ground carbon stock ranged from 1.3 to 67.7 Mg ha-1 and from 0.4 to 13.7 Mg ha-1, respectively. These values were similar to other studies in Thailand.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_30002_file35":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_access","date":[{"dateType":"Available","dateValue":"2024-06-18"}],"displaytype":"simple","fileDate":[{"fileDateType":"Issued","fileDateValue":"2017-03-17"}],"filename":"jircas_working_report85-_1-10.pdf","filesize":[{"value":"743KB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"jircas_working_report85-_1-10","objectType":"fulltext","url":"https://jircas.repo.nii.ac.jp/record/2000295/files/jircas_working_report85-_1-10.pdf"},"version_id":"cf4409bf-2f4e-4f0d-b99b-0da8b5f2bbf0"}]},"item_30002_funding_reference21":{"attribute_name":"助成情報","attribute_value_mlt":[{"subitem_award_titles":[{"subitem_award_title":"Improvement of Utilization Techniques of Forest Resources to Promote Sustainable Forestry","subitem_award_title_language":"en"}],"subitem_funder_identifiers":{"subitem_funder_identifier":"https://doi.org/10.13039/501100009472","subitem_funder_identifier_type":"Crossref Funder"},"subitem_funder_names":[{"subitem_funder_name":"Japan International Research Center for Agricultural Sciences","subitem_funder_name_language":"en"}]},{"subitem_award_titles":[{"subitem_award_title":"Improvement of Utilization Techniques of Forest Resources to Promote Sustainable Forestry","subitem_award_title_language":"en"}],"subitem_funder_identifiers":{"subitem_funder_identifier":"https://doi.org/10.13039/501100022245","subitem_funder_identifier_type":"Crossref Funder"},"subitem_funder_names":[{"subitem_funder_name":"Royal Forest Department (RFD)  [Thailand]","subitem_funder_name_language":"en"}]}]},"item_30002_geolocation20":{"attribute_name":"位置情報","attribute_value_mlt":[{"subitem_geolocation_place":[{"subitem_geolocation_place_text":"Thailand"},{"subitem_geolocation_place_text":"タイ"}]}]},"item_30002_identifier_registration17":{"attribute_name":"ID登録","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34556/0002000295","subitem_identifier_reg_type":"JaLC"}]},"item_30002_language12":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_30002_publisher10":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"Japan International Research Center for Agricultural Sciences","subitem_publisher_language":"en"}]},"item_30002_relation18":{"attribute_name":"関連情報","attribute_value_mlt":[{"subitem_relation_name":[{"subitem_relation_name_language":"en","subitem_relation_name_text":"Improvement of Utilization Techniques of Forest Resources to Promote Sustainable Forestry in Thailand"}],"subitem_relation_type":"isPartOf","subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.34556/0002000291","subitem_relation_type_select":"DOI"}}]},"item_30002_resource_type13":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"book part","resourceuri":"http://purl.org/coar/resource_type/c_3248"}]},"item_30002_source_identifier22":{"attribute_name":"収録物識別子","attribute_value_mlt":[{"subitem_source_identifier":"1341-710X","subitem_source_identifier_type":"PISSN"},{"subitem_source_identifier":"AA11159468","subitem_source_identifier_type":"NCID"}]},"item_30002_subject8":{"attribute_name":"主題","attribute_value_mlt":[{"subitem_subject":"Biomass estimation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Root biomass","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Wood density","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Carbon stock","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Tectona grandis","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_30002_title0":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Estimation of biomass and carbon stock in young teak plantations in Thailand","subitem_title_language":"en"}]},"item_30002_version_type15":{"attribute_name":"出版タイプ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_title":"Estimation of biomass and carbon stock in young teak plantations in Thailand","item_type_id":"40039","owner":"74","path":["1718084285672"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2024-06-18"},"publish_date":"2024-06-18","publish_status":"0","recid":"2000295","relation_version_is_last":true,"title":["Estimation of biomass and carbon stock in young teak plantations in Thailand"],"weko_creator_id":"74","weko_shared_id":-1},"updated":"2024-06-20T06:28:17.325320+00:00"}
