Actual levels of light and nutrient requirements for Bombax buonopozense and Khaya ivorensis tree species native of Ghana and Cedrela odorata (exotic) are not known. This study therefore attempted to find out the level of nutrient and light requirements as well as their interactive effect on growth and electron transport rate (a measure of photosynthetic process) of the species mentioned. Two-month old seedlings of the three species were grown for 14 weeks in five light regimes with three levels of nutrient treatments (I.e. 0 g, 5 g and 10 g of NPK) in each light regime and in replicates of two. The light treatments were : 1.00 RLI, 0.44 RLI, 0.15 RLI, 0.05 RLI and 0.01 RLI. Light and nutrient as well as their interaction significantly (p<0.05) influenced above and below ground growth of B. buonopozense and C. odorata seedlings while light treatment only significantly (p< 0.05) influenced above ground growth of K. ivorensis seedlings. Growth parameters I.e. height increment (HI), diameter increment (DI) , total growth increment (D^2HI) and root-shoot weight ratio (R/S) as well electron transport rate (ETR) increased with increasing relative light at higher nutrient supply for C. odorata and B. bonopozense. Where as in partial light treatment (0.44 RLI) growth and electron transport rate was high in the case of K. ivorensis. The nutrient treatments did not significantly (p<0.05) influence growth in K. ivorensis.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学農学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Miyazaki University","subitem_publisher_language":"en"}]},"item_10002_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AN00236503","subitem_source_identifier_type":"NCID"}]},"item_10002_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"05446066","subitem_source_identifier_type":"ISSN"}]},"item_10002_version_type_20":{"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":"ジマー, リチャード","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"中尾, 登志雄","creatorNameLang":"ja"},{"creatorName":"ナカオ, トシオ","creatorNameLang":"ja-Kana"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ゾー, ウー  ミン","creatorNameLang":"ja"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"GYIMAH, Richard","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"NAKAO, Toshio","creatorNameLang":"en"}],"nameIdentifiers":[{}]},{"creatorNames":[{"creatorName":"ZAW, OO  Min","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":"2020-06-21"}],"displaytype":"detail","filename":"KJ00004192530.pdf","filesize":[{"value":"1.1 MB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"KJ00004192530.pdf","url":"https://miyazaki-u.repo.nii.ac.jp/record/3187/files/KJ00004192530.pdf"},"version_id":"3c6a40f9-f17f-4b56-85b9-4c4c74ea6946"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"成長量, 電子伝達速度, 養分, 相対照度, 熱帯樹種","subitem_subject_language":"ja","subitem_subject_scheme":"Other"},{"subitem_subject":"Growth increments, Electron transport rate, Nutrient, Relative light intensity, Tropical tree species","subitem_subject_language":"en","subitem_subject_scheme":"Other"}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"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":"Effects of Light Intensity and Nutrient on Growth and Electron Transport Rate of Tropical Tree Seedlings (Bombax buonopozense, Khaya ivorensis and Cedrela odorata) found in Ghana","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Effects of Light Intensity and Nutrient on Growth and Electron Transport Rate of Tropical Tree Seedlings (Bombax buonopozense, Khaya ivorensis and Cedrela odorata) found in Ghana","subitem_title_language":"en"},{"subitem_title":"光強度と養分がガーナ産熱帯樹(Bombax buonopozense, Khaya ivorensis and Cedrela odorata)苗木の成長と電子伝達速度に及ぼす影響","subitem_title_language":"ja"}]},"item_type_id":"10002","owner":"5","path":["74","46","349","361"],"pubdate":{"attribute_name":"PubDate","attribute_value":"2007-06-28"},"publish_date":"2007-06-28","publish_status":"0","recid":"3187","relation_version_is_last":true,"title":["Effects of Light Intensity and Nutrient on Growth and Electron Transport Rate of Tropical Tree Seedlings (Bombax buonopozense, Khaya ivorensis and Cedrela odorata) found in Ghana"],"weko_creator_id":"5","weko_shared_id":2},"updated":"2023-07-30T03:03:51.559561+00:00"}
