Measurements during four successive years from 1982 to 1985 were made in Stand A, which consisted of young to middleaged trees, and for the years 1982 and 1983,in Stand B in which the trees were at the old growth stage. The results were as follows. 1. Pollen production rates, which were determined by the number of fallen male catkins per 1-hectare stand per year and the mean dry weight of pollen contained in catkin samples, were 41-220 kg/ha・yr for Stand A, and 27 and 77 kg/ha・yr for Stand B. The pollen content of the production rates of catkins bearing pollen was 40-55%, and that of the reproductive organs, 20-30%. 2. Production rates (by number) of pollen grains were determined to be 2.5×10^<12>-7.1×10^<12>/ha・yr for Stand A, and 1.6×10^<12> and 3.2×10^<12>/ha・yr for Stand B. 3. No differences were found among three sampled trees for each year with regard to the mean dry weight of pollen grains. However, the mean dry weight of pollen per catkin varied among the sampled trees because of the differences in the numbers of pollen grains per stamen, stamens per flower and flowers per catkin. 4. Changes in the mean dry weight of fallen catkins (without pollen) were slight among the years studied. However, annual fluctuations in the pollen production rates (maximum/minimum ratio : 5.4) were caused by differences in both the numbers of fallen catkins (max./min. ratio : 2.8) and the mean dry weight of pollen grains, which proportionally increased with increasing pollen production rates. 5. Little annual change was found in the numbers of pollen grains contained in catkin samples. 6. The old Stand B had a smaller number of fallen catkins than young Stand A. However, with regard to the total number of female flowers, including preripe and ripe fruits, there was little difference between the two stands. The lower number of ripe fruits in old Stand B might have been due to the low production rates (in number) of pollen grains.","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":"KJ00000079134.pdf","filesize":[{"value":"810.2 kB"}],"format":"application/pdf","mimetype":"application/pdf","url":{"label":"KJ00000079134.pdf","url":"https://kpu.repo.nii.ac.jp/record/5135/files/KJ00000079134.pdf"},"version_id":"41d2922f-349c-49c8-acad-94a60464b0bc"}]},"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":"オニグルミ林分の花粉生産速度(林学部門)","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"オニグルミ林分の花粉生産速度(林学部門)","subitem_title_language":"ja"}]},"item_type_id":"3","owner":"14","path":["430"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2017-02-20"},"publish_date":"2017-02-20","publish_status":"0","recid":"5135","relation_version_is_last":true,"title":["オニグルミ林分の花粉生産速度(林学部門)"],"weko_creator_id":"14","weko_shared_id":-1},"updated":"2024-03-06T01:09:05.082282+00:00"}
