Conditions of 35 and 60% shading were brought about covering the plants with two and six layers of white cheese cloth, respectively. Morphological features and dry matter production were determined three times at 10 or 14 day-intervals. 1. On reducing light intensity, plant height and leaf blade length significantly increased and the number of leaves and stems per plant remarkably decreased in most species. Total leaf area per pot increased under shaded conditions significantly in the grass species, but only slightly in the legumes. Root length was not affected by shading in most pasture plants. 2. Total weight of dry matter of temperate grasses was not affected by shading, while that of warm-season grasses and legumes decreased with severe light reduction. Leaf dry weight of most grass species did not differ significantly for all shading conditions, but that of legumes decreased greatly by shading. Root dry weight decreased significantly by shading in most species. 3. RGR (relative growth rate ) for most species remained constant though LAR (leaf area ratio) increased and NAR (net assimilation rate) decreased with shading. Increase in LAR was due primarily to increase in LWR (leaf weight ratio) for warm-season grasses and to increase in SLA (specific leaf area) for temperate grasses and legumes, respectively. 4. Based on dry matter production data, warm-season grasses and legumes adapt to light reduced by 30% or less in the summer season, and temperate grasses adapt to light reduced by as much as 60%.","subitem_description_type":"Abstract"},{"subitem_description":"夏季に，多年性牧草10種（寒地型イネ科牧草5種，寒\n地型マメ科牧草2種，暖地型牧草3種）を無遮光と白色\n寒冷紗によって相対日射量約60％と35％の遮光条件下で\nポット栽培した。牧草の形質と乾物量について10～14日\n間隔で調査して，乾物生産におよぼす遮光の影響につい\nて検討した。1）イネ科の牧草は，遮光によって草丈，葉身長が伸び，\n葉数，茎数が減少した。ポット当たりの葉面積はイネ\n科草種では増加したが，マメ科牧草では変わらなかっ\nた。大部分の草種の根長は遮光程度が変わっても変化\nがみられなかった。2）全乾物重は，寒地型イネ科牧草では，処理区間差は\n見られなかったが，暖地型牧草とマメ科牧草は，強遮\n光区で有意に減少した。葉重は，イネ科牧草では遮光\nによって変わらなかったが，マメ科牧草では減少した。\nまた，根重はほとんどの草種で減少した。\n3）ほとんどの草種のRGRは，遮光条件下においても\n無遮光と同程度に維持され。これは，各牧草とも\nLARを増大させて対応していた。このLARの増加は，\n暖地型牧草ではLWRを増加させることによってもた\nらされたのに対し，寒地型牧草ではSLAを増加させ\nることによってもたらされた。\n4）乾物生産量から判断して，夏季には暖地型と寒地型\nマメ科牧草は30％程度までの遮光下で，また，寒地型\nイネ科牧草は60％以内の遮光条件にそれぞれ適応でき\nると考えられる。","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"}]},"item_4_source_id_7":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"0915-0471","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":"AN10073846","subitem_source_identifier_type":"NCID"}]},"item_4_subject_16":{"attribute_name":"日本十進分類法","attribute_value_mlt":[{"subitem_subject":"616","subitem_subject_scheme":"NDC"}]},"item_4_text_18":{"attribute_name":"その他のタイトル","attribute_value_mlt":[{"subitem_text_language":"en","subitem_text_value":"Growth and Dry Matter Production of Pasture Plants Grown under Reduced Light Conditions of Summer Season"}]},"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":"森田, 脩","creatorNameLang":"ja"},{"creatorName":"Morita, Osamu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"後藤, 正和","creatorNameLang":"ja"},{"creatorName":"Goto, Masakazu","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"江原, 宏","creatorNameLang":"ja"},{"creatorName":"Ehara, Hiroshi","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":"AN100738460001203.pdf","filesize":[{"value":"633.4 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"AN100738460001203.pdf","url":"https://mie-u.repo.nii.ac.jp/record/5786/files/AN100738460001203.pdf"},"version_id":"ca979ed7-f4d5-4876-af33-4c384b2b9bab"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"Dry matter production","subitem_subject_scheme":"Other"},{"subitem_subject":"Growth analysis","subitem_subject_scheme":"Other"},{"subitem_subject":"Shading","subitem_subject_scheme":"Other"},{"subitem_subject":"Temperate grass and legum","subitem_subject_scheme":"Other"},{"subitem_subject":"Warm-season grass","subitem_subject_scheme":"Other"},{"subitem_subject":"寒地型牧草","subitem_subject_scheme":"Other"},{"subitem_subject":"乾物生産","subitem_subject_scheme":"Other"},{"subitem_subject":"遮光","subitem_subject_scheme":"Other"},{"subitem_subject":"生長解析","subitem_subject_scheme":"Other"},{"subitem_subject":"暖地型牧草","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":"夏季の遮光が牧草の生長ならびに乾物生産に及ぼす影響","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"夏季の遮光が牧草の生長ならびに乾物生産に及ぼす影響","subitem_title_language":"ja"}]},"item_type_id":"4","owner":"13","path":["455"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-04-17"},"publish_date":"2007-04-17","publish_status":"0","recid":"5786","relation_version_is_last":true,"title":["夏季の遮光が牧草の生長ならびに乾物生産に及ぼす影響"],"weko_creator_id":"13","weko_shared_id":-1},"updated":"2023-10-12T05:46:56.502064+00:00"}
