During the study, seasonal changes of those bud characteristics to day length and temperatures were investigated morphologically and physiologically. The effects of photoperiods and temperature on the terminal buds formation of P. euramericana were investigated. The results, there were two independent physiological reaction systems in day and night length funcion respectively in the process of buds formation, were obtained. It was speculated that balance of both physiological reaction systems decide the critical day length to bud formation in P. euramericana. From study of mechanism of lammas shoots formation in P. densiflora, it was found the winter buds could re-elongate when they have 90 to 100 leaf primordia in their buds under the condition longer than 14-h day length. From results of reaction in winter buds of P. euramericana and P. densiflora to temperatures and day length, dormancy stage of both tree species can be distinguished as fellows, First is Dormancy induction stage, Second is Winter dormancy stage and Third is Dormancy release stage. And it was recognized for the first time that Inner growth stage existed following dormancy release before growing. Through this study, it was emphasized that the knowledge of responses to the environment of buds in each trees and their annual life cycle was significant in forest conservation and silviculture field.","subitem_description_type":"Abstract"}]},"item_4_publisher_30":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"三重大学生物資源学部附属演習林"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0916-8974","subitem_source_identifier_type":"PISSN"}]},"item_4_source_id_9":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN10438810","subitem_source_identifier_type":"NCID"}]},"item_4_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Studies on Dormancy in Woody Plants"}]},"item_4_text_63":{"attribute_name":"ノート","attribute_value_mlt":[{"subitem_text_value":"Agropedia提供データ"}]},"item_4_text_65":{"attribute_name":"資源タイプ（三重大）","attribute_value_mlt":[{"subitem_text_value":"Departmental Bulletin Paper / 紀要論文"}]},"item_4_version_type_15":{"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":"櫛田, 達矢","creatorNameLang":"ja"},{"creatorName":"Kushida, Tatsuya","creatorNameLang":"en"}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-18"}],"displaytype":"detail","filename":"AN104388100002401.pdf","filesize":[{"value":"6.6 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN104388100002401.pdf","url":"https://mie-u.repo.nii.ac.jp/record/5669/files/AN104388100002401.pdf"},"version_id":"545af039-f54e-4550-b90f-5c06fdc050be"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"1年間のライフサイクル","subitem_subject_scheme":"Other"},{"subitem_subject":"環境反応性","subitem_subject_scheme":"Other"},{"subitem_subject":"休眠","subitem_subject_scheme":"Other"},{"subitem_subject":"森林保全","subitem_subject_scheme":"Other"},{"subitem_subject":"annual life cycle","subitem_subject_scheme":"Other"},{"subitem_subject":"dormancy","subitem_subject_scheme":"Other"},{"subitem_subject":"forest conservation","subitem_subject_scheme":"Other"},{"subitem_subject":"responses to the environment","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":"樹木の休眠に関する研究","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"樹木の休眠に関する研究","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"13","path":["441"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-06-06"},"publish_date":"2007-06-06","publish_status":"0","recid":"5669","relation_version_is_last":true,"title":["樹木の休眠に関する研究"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-10-12T01:03:53.541545+00:00"}
