Genetic diversity of the mother stand was maintained in the progeny stand for the most part. However some genetic offsets were observed in specific loci, which might be caused by biased seed collection from a limited number of mother trees. Therefore seed collection from large a number of mother trees is necessary to conserve the genetic diversity of the mother stand. Comparison between the progeny stand and the cutting stand of which stocks were taken from the progeny stand was undertaken. The expected heterozygosity of the cutting stand was lower than that of the progeny stand owing to the existence of plural individuals belonging to same clones. However, the expeceted heterozygosity of the cutting stand was almost the same as the progeny stand when individuals belonging to the same clone were considered as individuals. Accordingly, it is possible to conserve the genetic diversity even in a cutting stand by taking stocks from a reasonable number of mother trees.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"54478","nameIdentifierScheme":"WEKO"}],"names":[{"name":"TANG, Ding-Qin"}]},{"nameIdentifiers":[{"nameIdentifier":"54479","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IKEDA, Hiroyuki"}]},{"nameIdentifiers":[{"nameIdentifier":"54480","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WATANABE, Yoshihiro"}]},{"nameIdentifiers":[{"nameIdentifier":"54481","nameIdentifierScheme":"WEKO"}],"names":[{"name":"MURASE, Kazutaka"}]},{"nameIdentifiers":[{"nameIdentifier":"54482","nameIdentifierScheme":"WEKO"}],"names":[{"name":"IDE, Yuji"}]}]},"item_4_publisher_20":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"東京大学大学院農学生命科学研究科附属演習林"}]},"item_4_source_id_10":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00162451","subitem_source_identifier_type":"NCID"}]},"item_4_source_id_8":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"03716007","subitem_source_identifier_type":"ISSN"}]},"item_4_subject_15":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"610","subitem_subject_scheme":"NDC"}]},"item_4_text_21":{"attribute_name":"出版者別名","attribute_value_mlt":[{"subitem_text_value":"The Tokyo University Forests"}]},"item_4_text_4":{"attribute_name":"著者所属","attribute_value_mlt":[{"subitem_text_value":"東京大学大学院農学生命科学研究科"},{"subitem_text_value":"東京大学農学部附属演習林樹芸研究所"},{"subitem_text_value":"東京大学農学部附属演習林千葉演習林"},{"subitem_text_value":"Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"Arboricultural Research Institute, Faculty of Agriculture, The University of Tokyo"},{"subitem_text_value":"University Forest in Chiba, Faculty of Agriculture, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"湯, 定欽"}],"nameIdentifiers":[{"nameIdentifier":"54473","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"池田, 裕行"}],"nameIdentifiers":[{"nameIdentifier":"54474","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡邉, 良弘"}],"nameIdentifiers":[{"nameIdentifier":"54475","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"村瀬, 一隆"}],"nameIdentifiers":[{"nameIdentifier":"54476","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"井出, 雄二"}],"nameIdentifiers":[{"nameIdentifier":"54477","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":"2017-06-09"}],"displaytype":"detail","filename":"esrh099006.pdf","filesize":[{"value":"829.2 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh099006.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25397/files/esrh099006.pdf"},"version_id":"eda1f891-9931-4095-903a-f462a5779f38"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"アイソザイム","subitem_subject_scheme":"Other"},{"subitem_subject":"遺伝的多様性","subitem_subject_scheme":"Other"},{"subitem_subject":"ヒノキ","subitem_subject_scheme":"Other"},{"subitem_subject":"実生林分","subitem_subject_scheme":"Other"},{"subitem_subject":"さし木林分","subitem_subject_scheme":"Other"},{"subitem_subject":"Isozyme","subitem_subject_scheme":"Other"},{"subitem_subject":"Genetic diversity","subitem_subject_scheme":"Other"},{"subitem_subject":"Chamaecyparis obtusa","subitem_subject_scheme":"Other"},{"subitem_subject":"Seedling stand","subitem_subject_scheme":"Other"},{"subitem_subject":"Cutting stand","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":"異なる繁殖方法により造成されたヒノキ人工林分の遺伝的多様性","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"異なる繁殖方法により造成されたヒノキ人工林分の遺伝的多様性"}]},"item_type_id":"4","owner":"1","path":["2544","2543"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25397","relation_version_is_last":true,"title":["異なる繁殖方法により造成されたヒノキ人工林分の遺伝的多様性"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:39.967928+00:00"}
