We hand-pollinated two chloroplast DNA haplotypes (Ja/B1) of Aucuba japonica, a landscaping and horticultural plant species. The pollination success rate was calculated as the percentage of fertilized flowers to the total number of pollinated flowers. The average pollination success rate was 82.1% for Ja (female) × Ja (male), 75.3% for Ja × B1, 85.3% for B1 × Ja, and 78.6% for B1 × B1. A generalized linear model revealed no significant effects of paternal haplotype on the pollination success rate, except in the case of one maternal plant. Thus, natural hybridization between an introduced haplotype and a native haplotype can occur and the genetic composition of local populations of Aucuba japonica would cryptically be changed in this way.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"53645","nameIdentifierScheme":"WEKO"}],"names":[{"name":"YANO, Hatsumi"}]},{"nameIdentifiers":[{"nameIdentifier":"53646","nameIdentifierScheme":"WEKO"}],"names":[{"name":"GOTO, Susumu"}]}]},"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生圏システム学専攻緑地創成学研究室"},{"subitem_text_value":"東京大学大学院農学生命科学研究科附属演習林田無試験地"},{"subitem_text_value":"Laboratory of Landscape Ecology and Planning, Graduate School of Agricultural and Life Sciences, The University of Tokyo"},{"subitem_text_value":"Experimental Station at Tanashi, University Forests, Graduate School of Agricultural and Life Sciences, The University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"矢野, 初美"}],"nameIdentifiers":[{"nameIdentifier":"53643","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"後藤, 晋"}],"nameIdentifiers":[{"nameIdentifier":"53644","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":"ersh120002.pdf","filesize":[{"value":"895.7 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"ersh120002.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25268/files/ersh120002.pdf"},"version_id":"6570a79e-2d00-4d77-9d2d-496a55d5f616"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"園芸","subitem_subject_scheme":"Other"},{"subitem_subject":"種内交雑","subitem_subject_scheme":"Other"},{"subitem_subject":"人工受粉実験","subitem_subject_scheme":"Other"},{"subitem_subject":"都市域","subitem_subject_scheme":"Other"},{"subitem_subject":"葉緑体DNAハプロタイプ","subitem_subject_scheme":"Other"},{"subitem_subject":"horticulture","subitem_subject_scheme":"Other"},{"subitem_subject":"intraspecific hybridization","subitem_subject_scheme":"Other"},{"subitem_subject":"hand pollination experiment","subitem_subject_scheme":"Other"},{"subitem_subject":"urban","subitem_subject_scheme":"Other"},{"subitem_subject":"area","subitem_subject_scheme":"Other"},{"subitem_subject":"chloroplast DNA haplotype","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":"造園・園芸利用種アオキにおける異なる葉緑体ハプロタイプ間の交雑","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"造園・園芸利用種アオキにおける異なる葉緑体ハプロタイプ間の交雑"}]},"item_type_id":"4","owner":"1","path":["2502","2501"],"pubdate":{"attribute_name":"公開日","attribute_value":"2012-07-17"},"publish_date":"2012-07-17","publish_status":"0","recid":"25268","relation_version_is_last":true,"title":["造園・園芸利用種アオキにおける異なる葉緑体ハプロタイプ間の交雑"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:34.898046+00:00"}
