We examined whether stands in which many Q. serrata seedlings had been\nestablished had become Q. serrata-dominated stands 14 years after cutting. In a stand without mechanical ground treatment by a small-sized excavator， the resu1ting secondary stand was dominated by Magnolia obovata and Castanea crenata, and regenerating Q. serrata trees were not found. By contrast，i n as tand with mechanical ground treatment, many regenerating Q. serrata trees were found. However, the relative dominance of regenerating Q. serrata trees based on basal area was lower than those of M. obovata\nand Swida controversa trees. In addition, the height increment of regenerating Q. serrata trees was also lower than those of M. obovata trees. It appears that the height growth of regenerating Q. serrata trees was suppressed by severe competition for light with the other trees such as M. obovata and S. controversa trees and the resulting secondary stand was dominated by M. obovata and S. controversa. Clearing and improvemen cutting are essential to remove woody vegetation except for Q. serrata to achieve the successful regeneration of Q. serrata trees.","subitem_description_type":"Other"}]},"item_41_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{}],"names":[{"name":"IMAIZUMI, Shoko"}]},{"nameIdentifiers":[{}],"names":[{"name":"KUNISAKI, Takashi"}]}]},"item_41_publisher_14":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"岩手大学農学部附属寒冷フィールドサイエンス教育研究センター"}]},"item_41_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0286-4339","subitem_source_identifier_type":"ISSN"}]},"item_41_text_4":{"attribute_name":"著者(機関)","attribute_value_mlt":[{"subitem_text_value":"岩手大学農学部共生環境課程"},{"subitem_text_value":"岩手大学環境科学系"}]},"item_41_version_type_27":{"attribute_name":"著者版フラグ","attribute_value_mlt":[{"subitem_version_resource":"http://purl.org/coar/version/c_970fb48d4fbd8a85","subitem_version_type":"VoR"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"今泉, 祥子"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"國崎, 貴嗣"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2016-11-14"}],"displaytype":"detail","filename":"biuf-n43p1-15.pdf","filesize":[{"value":"569.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"biuf-n43p1-15.pdf","url":"https://iwate-u.repo.nii.ac.jp/record/8992/files/biuf-n43p1-15.pdf"},"version_id":"457f78f1-9632-4773-af44-4c47380ac219"}]},"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":"機械地床処理を導入したコナラ天然下種更新試験地における14年後の更新状況","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"機械地床処理を導入したコナラ天然下種更新試験地における14年後の更新状況"}]},"item_type_id":"41","owner":"3","path":["1506"],"pubdate":{"attribute_name":"公開日","attribute_value":"2013-02-22"},"publish_date":"2013-02-22","publish_status":"0","recid":"8992","relation_version_is_last":true,"title":["機械地床処理を導入したコナラ天然下種更新試験地における14年後の更新状況"],"weko_creator_id":"3","weko_shared_id":-1},"updated":"2023-05-16T11:19:37.226342+00:00"}
