We tested this proportionality for the herb Helianthus tuberosus. During growth, we repeatedly measured the percentage of leaves with high, medium, and low photosynthetic capacity to estimate the whole-plant sum of photosynthetic capacity. We found that the whole-plant sum of the light-saturated photosynthetic rate of leaves is proportional to the whole-plant leaf area, disregarding the dynamics of the leaf population. We also found that the daily photosynthesis of each leaf appeared as a linear function of the light-saturated photosynthetic rate of that leaf, as predicted by the optimization theory. Using those results, we expressed whole-plant photosynthetic rate as a product of the light-saturated whole-plant photosynthetic rate and an efficiency index that reflects resource limitation as in the logistic equation. This efficiency decreased with increasing leaf area, reflecting light limitation. Therefore, realized whole-plant photosynthetic rate is not proportional to leaf area. These \"diminishing returns\" are well explained by a simple saturating curve, such as the logistic equation.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_2_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"The American Society of Naturalists","subitem_publisher_language":"en"}]},"item_2_rights_15":{"attribute_name":"権利","attribute_value_mlt":[{"subitem_rights":"The American Society of Naturalists","subitem_rights_language":"en"}]},"item_2_source_id_11":{"attribute_name":"書誌レコードID","attribute_value_mlt":[{"subitem_source_identifier":"AA00521767","subitem_source_identifier_type":"NCID"}]},"item_2_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"00030147","subitem_source_identifier_type":"PISSN"}]},"item_2_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":[{"creatorAffiliations":[{"affiliationNameIdentifiers":[{"affiliationNameIdentifier":""}],"affiliationNames":[{"affiliationName":""}]}],"creatorNames":[{"creatorName":"Koyama, Kohei","creatorNameLang":"en"},{"creatorName":"小山, 耕平","creatorNameLang":"ja"}],"familyNames":[{},{}],"givenNames":[{},{}],"nameIdentifiers":[{},{},{},{}]},{"creatorNames":[{"creatorName":"Kikuzawa, Kihachiro","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":"2018-01-30"}],"displaytype":"detail","filename":"koyama173(5),640-649,2009.pdf","filesize":[{"value":"458.3 kB"}],"format":"application/pdf","licensetype":"license_note","mimetype":"application/pdf","url":{"label":"koyama173(5),640-649,2009.pdf","url":"https://obihiro.repo.nii.ac.jp/record/663/files/koyama173(5),640-649,2009.pdf"},"version_id":"a1f3eac3-7ffb-46c0-b8e5-d36f06b208ce"}]},"item_keyword":{"attribute_name":"キーワード","attribute_value_mlt":[{"subitem_subject":"metabolic scaling theory","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"whole‐plant photosynthesis","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"allometry","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"leaf demography","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"logistic equation","subitem_subject_language":"en","subitem_subject_scheme":"Other"},{"subitem_subject":"Helianthus tuberosus (Jerusalem artichoke)","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":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Is whole-plant photosynthetic rate proportional to leaf area?
