Japono-gigas). The experiment were studied, repeated twice at Tokyo University Experiment Station, Tanasi, Tokyo. Young cuttings of clones mentioned above were used for the experiment. The plants were grown in pots arranged in line, and the pots were burried to their rims in the field. The measurements of height growth, leaf area and leaf longevity, were carried out at a week interval through a whole growing season, and the plants employed in the experiment, finally were dug out for the calculation of total dry weight increment. In both years, total dry weight increment were in proportion to both leaf area duration and total leaf area per plant, regardless of clonal differences. As a result, net assimilation rate was similar among all poplar clones. However, total leaf area per plant showed a dignificant difference among the clones used in the present experiment, and this is attributed to difference among clones in both years. Furthermore the difference in relationship between total dry weight increment and total leaf area per plant among clones, were attributed to leaf longevity among clones in growing season. The differences in leaf longevity were remarkable among the clones in a season of vigorous growth. For example, OP20 continuously shed old leaves and regenerated new leaves in short interval, on the other hand, OP206 shed scarcely and their leaves were long-lived. The results as above mentioned, showed that the growth of poplar clones in this experiment highly depends on total leaf area per plant and leaf longevity through the growing season.","subitem_description_type":"Abstract"}]},"item_4_full_name_3":{"attribute_name":"著者別名","attribute_value_mlt":[{"nameIdentifiers":[{"nameIdentifier":"55158","nameIdentifierScheme":"WEKO"}],"names":[{"name":"SHIBA, Yoshihiro"}]}]},"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":"Department of Forestry, Faculty of Agriculture, University of Tokyo"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"斯波, 義宏"}],"nameIdentifiers":[{"nameIdentifier":"55157","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":"esrh082001.pdf","filesize":[{"value":"530.0 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"esrh082001.pdf","url":"https://repository.dl.itc.u-tokyo.ac.jp/record/25515/files/esrh082001.pdf"},"version_id":"9c02842d-695d-417b-a3ae-37f0dba44298"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"ポプラ","subitem_subject_scheme":"Other"},{"subitem_subject":"NAR（純同化率）","subitem_subject_scheme":"Other"},{"subitem_subject":"LAD（葉積）","subitem_subject_scheme":"Other"},{"subitem_subject":"累計葉面積","subitem_subject_scheme":"Other"},{"subitem_subject":"葉の寿命","subitem_subject_scheme":"Other"},{"subitem_subject":"Poplar","subitem_subject_scheme":"Other"},{"subitem_subject":"NAR (net assimilation rate)","subitem_subject_scheme":"Other"},{"subitem_subject":"LAD (leaf area duration)","subitem_subject_scheme":"Other"},{"subitem_subject":"Total amount of leaf area per plant","subitem_subject_scheme":"Other"},{"subitem_subject":"Leaf longevity","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":"ポプラクローンの総乾物増加量と純同化率(NAR), 累計葉量, 葉積(LDA), 葉の寿命の関係","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"ポプラクローンの総乾物増加量と純同化率(NAR), 累計葉量, 葉積(LDA), 葉の寿命の関係"}]},"item_type_id":"4","owner":"1","path":["2578","2577"],"pubdate":{"attribute_name":"公開日","attribute_value":"2014-09-03"},"publish_date":"2014-09-03","publish_status":"0","recid":"25515","relation_version_is_last":true,"title":["ポプラクローンの総乾物増加量と純同化率(NAR), 累計葉量, 葉積(LDA), 葉の寿命の関係"],"weko_creator_id":"1","weko_shared_id":null},"updated":"2022-12-19T04:03:43.932250+00:00"}
