Careful searches into natural forests, in which both species grow mixed or next stand each other, were carried out in 25 locations in 14 districts, Hokkaido, during the period from 1986 till 1988. And nine trees to be identified as natural hybrids were sifted out from five stands in Yamabe (two stands), Yukomanbetu, Biei and Oketo. 2. Among them, four individuals lie between both species in such characteristics as the time of bud-opening, the abundance and arrangement of stomatal lines and other characters of needles, the hairiness of current-year branchlets and others (hereafter these called g×jA type). The other five (g×jB type) represent features very similar to those of Yezo spruce, though easily distinguished form this by the pubescence of current-year branchlets and less abundance of stomatal lines on the upper surface of needles. 3. g×jA individuals are well coincident in many characteristics to g×jF1 individuals found in the sample plantation, while the g×jB are supposed as offsprings of F1 backcrossed to Yezo spruce, i.e., F1×j. 4. Those seedlings selected as hybrids out of the stock families in the nursery in 1982 and planted in the experimental fields represent better growth than both parental species at the ages of 12 and 14 years. But they are similar to Yezo spruce in the scarce formation of lateral branchlets on the current-year growth of main axes.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55229","nameIdentifierScheme":"WEKO"}],"names":[{"name":"HAMAYA, Toshio"}]},{"nameIdentifiers":[{"nameIdentifier":"55230","nameIdentifierScheme":"WEKO"}],"names":[{"name":"WATANABE, Sadamoto"}]},{"nameIdentifiers":[{"nameIdentifier":"55231","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KAJI, Mikio"}]},{"nameIdentifiers":[{"nameIdentifier":"55232","nameIdentifierScheme":"WEKO"}],"names":[{"name":"KURAHASHI, Akio"}]},{"nameIdentifiers":[{"nameIdentifier":"55233","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SASAKI, Chubei"}]},{"nameIdentifiers":[{"nameIdentifier":"55234","nameIdentifierScheme":"WEKO"}],"names":[{"name":"OGASAWARA, Shigeo"}]}]},"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":"東京大学農学部林学科"},{"subitem_text_value":"東京大学農学部附属北海道演習林"},{"subitem_text_value":"Department of Forestry, Faculty of Agriculture, University of Tokyo"},{"subitem_text_value":"University Forest in Hokkaido, Faculty of Agriculture, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"濱谷, 稔夫"}],"nameIdentifiers":[{"nameIdentifier":"55223","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"渡邊, 定元"}],"nameIdentifiers":[{"nameIdentifier":"55224","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"梶, 幹男"}],"nameIdentifiers":[{"nameIdentifier":"55225","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"倉橋, 昭夫"}],"nameIdentifiers":[{"nameIdentifier":"55226","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"佐々木, 忠兵衛"}],"nameIdentifiers":[{"nameIdentifier":"55227","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"小笠原, 繁男"}],"nameIdentifiers":[{"nameIdentifier":"55228","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":"esrh081005.pdf","filesize":[{"value":"2.0 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh081005.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25530/files/esrh081005.pdf"},"version_id":"20886d12-eec7-4a8d-8b5e-b8ba464132bb"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"アカエゾマツ","subitem_subject_scheme":"Other"},{"subitem_subject":"エゾマツ","subitem_subject_scheme":"Other"},{"subitem_subject":"天然雑種","subitem_subject_scheme":"Other"},{"subitem_subject":"節間雑種","subitem_subject_scheme":"Other"},{"subitem_subject":"形態","subitem_subject_scheme":"Other"},{"subitem_subject":"生育","subitem_subject_scheme":"Other"},{"subitem_subject":"Saghalien spruce","subitem_subject_scheme":"Other"},{"subitem_subject":"Yezo spruce","subitem_subject_scheme":"Other"},{"subitem_subject":"Natural hybrid","subitem_subject_scheme":"Other"},{"subitem_subject":"Morphology","subitem_subject_scheme":"Other"},{"subitem_subject":"Growth","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":"アカエゾマツとエゾマツの天然雑種の形態的並びに生育上の特徴","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"アカエゾマツとエゾマツの天然雑種の形態的並びに生育上の特徴"}]},"item_type_id":"4","owner":"1","path":["2580","2579"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25530","relation_version_is_last":true,"title":["アカエゾマツとエゾマツの天然雑種の形態的並びに生育上の特徴"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:59:51.790743+00:00"}
