Compared with the other mature Shii stands, production rates of male catkins in the young study stand were lower and those of female flowers were equal. This difference produced small M/F and P/O ratios (male to female flowers/inflorescences and pollen to ovules on a land-area basis, respectively), representing high efficiency of seed production. Large year-to-year fluctuations in the production rates of male catkins were recognized, the maximum/minimum rate being 12. The decrease in the number of female flowers in an unproductive year was larger than that of male frowers. The large number of female inflorescences was reduced within a year after flowering and that of immature fruits was reduced from infructescences within the nut growing season of the following year. Little growth of immature fruits was recognized, corresponding to 3.0% of the mean weight of mature nuts. The proportion of infructescences borne in the nut growing season ranged from 6% in an unproductive year to 44% in a productive one. That of fruits ranged from 0.5% to 19%, of which the proportion of fruits that matured was about 60%, regardless of nut yield. The assimilation product necessary for producing a single nut was similar to that in other mature stands.","subitem_description_language":"en","subitem_description_type":"Other"}]},"item_3_source_id_1":{"attribute_name":"雑誌書誌ID","attribute_value_mlt":[{"subitem_source_identifier":"AN00062275","subitem_source_identifier_type":"NCID"}]},"item_3_source_id_20":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00757373","subitem_source_identifier_type":"PISSN"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"齋藤, 秀樹","creatorNameLang":"ja"},{"creatorName":"サイトウ, ヒデキ","creatorNameLang":"ja-Kana"},{"creatorName":"Saito, Hideki","creatorNameLang":"en"}],"familyNames":[{},{},{}],"givenNames":[{},{},{}],"nameIdentifiers":[{}]}]},"item_files":{"attribute_name":"ファイル情報","attribute_type":"file","attribute_value_mlt":[{"accessrole":"open_date","date":[{"dateType":"Available","dateValue":"2017-02-20"}],"displaytype":"detail","filename":"KJ00000079215.pdf","filesize":[{"value":"1.3 MB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000079215.pdf","url":"https://kpu.repo.nii.ac.jp/record/5216/files/KJ00000079215.pdf"},"version_id":"b6673aaf-55ee-4c29-870e-aabbc1716dd4"}]},"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"}]},"item_title":"若いシイ林の種子生産様式(林学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"若いシイ林の種子生産様式(林学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["438"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"5216","relation_version_is_last":true,"title":["若いシイ林の種子生産様式(林学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-03-01T00:36:00.852904+00:00"}
