Since three individuals of T. yadoriki had fallen on the ground, which had parasitized on branches of Quercus acutissima at Nara University of Education (Nara City, western Japan) owing to the attack of typhoon No. 21 in 2018, we collected and weighed those samples. Mean dry weight of three T. yadoriki was 4725.7 g (2490.9 ‒ 8115.3 g), including 17.8% of leaf, 2.9% of flower bud, 65.8% of twigs, and 13.5% of parasitic root (estimated) . In order to clarify the size of T. yadoriki on the canopy, we defined multiplied volume index (MVI; m3), i.e., volume of the hypothesized cuboid containing T. yadoriki. Mean MIV was 4.9 m3 (2.2-7.1 m3) and correlated with the dry weight of T. yadoriki̶dry weight of T. yadoriki =-315.3 + 10 29.6 × MVI. Adopting density of T. yadoriki in an evergreen broad-leaved forest, above ground biomass of T. yadoriki was estimated to be 170.1 kg/ha, which was suggested to be very small value for the relatively high dominance of litter fall in the evergreen broad-leaved forest.","subitem_description_type":"Abstract"}]},"item_3_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"Tsujino, Riyou"}]},{"nameIdentifiers":[{}],"names":[{"name":"Matsui, Kiyoshi"}]}]},"item_3_publisher_32":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"奈良教育大学自然環境教育センター "}]},"item_3_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"21887187","subitem_source_identifier_type":"ISSN"}]},"item_3_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA11996234","subitem_source_identifier_type":"NCID"}]},"item_3_version_type_15":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"辻野, 亮"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"松井, 淳"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2019-04-09"}],"displaytype":"detail","filename":"BCNEE(20)_37-42.pdf","filesize":[{"value":"3.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"BCNEE(20)_37-42","url":"https://nara-edu.repo.nii.ac.jp/record/13228/files/BCNEE(20)_37-42.pdf"},"version_id":"5c12ae43-8fef-4138-b00e-d0528bdfeca5"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"半寄生","subitem_subject_scheme":"Other"},{"subitem_subject":"現存量","subitem_subject_scheme":"Other"},{"subitem_subject":"乗算体積指数","subitem_subject_scheme":"Other"},{"subitem_subject":"奈良市","subitem_subject_scheme":"Other"},{"subitem_subject":"乾燥重量","subitem_subject_scheme":"Other"},{"subitem_subject":"hemiparasite","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"biomass","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"multiplied volume index","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Nara City","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"dry weight","subitem_subject_language":"en","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"}]},"item_title":"台風で落下した半寄生樹木オオバヤドリギの乾燥重量データ","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"台風で落下した半寄生樹木オオバヤドリギの乾燥重量データ"},{"subitem_title":"Dry weight data of hemiparasitic plant Taxillus yadoriki fallen by a typhoon attack.","subitem_title_language":"en"}]},"item_type_id":"3","owner":"8","path":["1727"],"pubdate":{"attribute_name":"公開日","attribute_value":"2019-04-09"},"publish_date":"2019-04-09","publish_status":"0","recid":"13228","relation_version_is_last":true,"title":["台風で落下した半寄生樹木オオバヤドリギの乾燥重量データ"],"weko_creator_id":"8","weko_shared_id":-1},"updated":"2023-05-15T10:09:48.243957+00:00"}
