In this study blue light dose-response curves were made for the photosynthetic properties and related developmental characteristics of cucumber leaves that were grown at an equal irradiance under seven different combinations of red and blue light provided by light-emitting diodes. Only the leaves developed under red light alone (0% blue) displayed dysfunctional photosynthetic operation, characterized by a suboptimal and heterogeneously distributed dark-adapted F(v)/F(m), a stomatal conductance unresponsive to irradiance, and a relatively low light-limited quantum yield for CO(2) fixation. Only 7% blue light was sufficient to prevent any overt dysfunctional photosynthesis, which can be considered a qualitatively blue light effect. The photosynthetic capacity (A(max)) was twice as high for leaves grown at 7% blue compared with 0% blue, and continued to increase with increasing blue percentage during growth measured up to 50% blue. At 100% blue, A(max) was lower but photosynthetic functioning was normal. The increase in A(max) with blue percentage (0-50%) was associated with an increase in leaf mass per unit leaf area (LMA), nitrogen (N) content per area, chlorophyll (Chl) content per area, and stomatal conductance. Above 15% blue, the parameters A(max), LMA, Chl content, photosynthetic N use efficiency, and the Chl:N ratio had a comparable relationship as reported for leaf responses to irradiance intensity. It is concluded that blue light during growth is qualitatively required for normal photosynthetic functioning and quantitatively mediates leaf responses resembling those to irradiance intensity. 000009587 536__ $$0G:(DE-Juel1)FUEK407$$2G:(DE-HGF)$$aTerrestrische Umwelt$$cP24$$x0 000009587 588__ $$aDataset connected to Web of Science, Pubmed 000009587 65320 $$2Author$$aBlue light 000009587 65320 $$2Author$$achlorophyll fluorescence imaging 000009587 65320 $$2Author$$acucumber (Cucumis sativus) 000009587 65320 $$2Author$$adose-response curves 000009587 65320 $$2Author$$aleaf mass per unit leaf area (LMA) 000009587 65320 $$2Author$$alight-emitting diodes (LEDs) 000009587 65320 $$2Author$$aphotoinhibition 000009587 65320 $$2Author$$aphotosynthetic capacity 000009587 65320 $$2Author$$ared light 000009587 65320 $$2Author$$astarch accumulation 000009587 650_2 $$2MeSH$$aChlorophyll: analysis 000009587 650_2 $$2MeSH$$aChlorophyll: metabolism 000009587 650_2 $$2MeSH$$aCucumis sativus: chemistry 000009587 650_2 $$2MeSH$$aCucumis sativus: growth & development 000009587 650_2 $$2MeSH$$aCucumis sativus: metabolism 000009587 650_2 $$2MeSH$$aCucumis sativus: radiation effects 000009587 650_2 $$2MeSH$$aLight 000009587 650_2 $$2MeSH$$aNitrogen: analysis 000009587 650_2 $$2MeSH$$aNitrogen: metabolism 000009587 650_2 $$2MeSH$$aPhotosynthesis: radiation effects 000009587 650_2 $$2MeSH$$aPlant Leaves: chemistry 000009587 650_2 $$2MeSH$$aPlant Leaves: growth & development 000009587 650_2 $$2MeSH$$aPlant Leaves: metabolism 000009587 650_2 $$2MeSH$$aPlant Leaves: radiation effects 000009587 650_7 $$01406-65-1$$2NLM Chemicals$$aChlorophyll 000009587 650_7 $$07727-37-9$$2NLM Chemicals$$aNitrogen 000009587 650_7 $$2WoSType$$aJ 000009587 650_7 $$aBlue light 000009587 650_7 $$achlorophyll fluorescence imaging 000009587 650_7 $$acucumber (Cucumis sativus) 000009587 650_7 $$adose–response curves 000009587 650_7 $$aleaf mass per unit leaf area (LMA) 000009587 650_7 $$alight-emitting diodes (LEDs) 000009587 650_7 $$aphotoinhibition 000009587 650_7 $$aphotosynthetic capacity 000009587 650_7 $$ared light 000009587 650_7 $$astarch accumulation 000009587 7001_ $$0P:(DE-HGF)0$$aTrouwborst, G.$$b1 000009587 7001_ $$0P:(DE-HGF)0$$aMaljaars, H.$$b2 000009587 7001_ $$0P:(DE-Juel1)129384$$aPoorter, H.$$b3$$uFZJ 000009587 7001_ $$0P:(DE-HGF)0$$avan Ieperen, W.$$b4 000009587 7001_ $$0P:(DE-HGF)0$$aHarbinson, J.$$b5 000009587 773__ $$0PERI:(DE-600)1466717-4$$a10.1093/jxb/erq132$$gVol. 61, p. 3107 - 3117$$p3107 - 3117$$q61<3107 - 3117$$tThe @journal of experimental botany$$v61$$x0022-0957$$y2010 000009587 8567_ $$2Pubmed Central$$uhttp://www.ncbi.nlm.nih.gov/pmc/articles/PMC2892149 000009587 8564_ $$uhttps://juser.fz-juelich.de/record/9587/files/J.Exp.Bot._2010_61.11_3107-3117.pdf$$yOpenAccess 000009587 8564_ $$uhttps://juser.fz-juelich.de/record/9587/files/J.Exp.Bot._2010_61.4_1031-39.pdf$$yOpenAccess 000009587 8564_ $$uhttps://juser.fz-juelich.de/record/9587/files/J.Exp.Bot._2010_61.11_3107-3117.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000009587 8564_ $$uhttps://juser.fz-juelich.de/record/9587/files/J.Exp.Bot._2010_61.11_3107-3117.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000009587 8564_ $$uhttps://juser.fz-juelich.de/record/9587/files/J.Exp.Bot._2010_61.11_3107-3117.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000009587 8564_ $$uhttps://juser.fz-juelich.de/record/9587/files/J.Exp.Bot._2010_61.4_1031-39.jpg?subformat=icon-1440$$xicon-1440$$yOpenAccess 000009587 8564_ $$uhttps://juser.fz-juelich.de/record/9587/files/J.Exp.Bot._2010_61.4_1031-39.jpg?subformat=icon-180$$xicon-180$$yOpenAccess 000009587 8564_ $$uhttps://juser.fz-juelich.de/record/9587/files/J.Exp.Bot._2010_61.4_1031-39.jpg?subformat=icon-640$$xicon-640$$yOpenAccess 000009587 909CO $$ooai:juser.fz-juelich.de:9587$$pdnbdelivery$$pVDB$$pdriver$$popen_access$$popenaire 000009587 915__ $$0StatID:(DE-HGF)0010$$aJCR/ISI refereed 000009587 915__ $$0StatID:(DE-HGF)0510$$2StatID$$aOpenAccess 000009587 9141_ $$y2010 000009587 9131_ $$0G:(DE-Juel1)FUEK407$$bErde und Umwelt$$kP24$$lTerrestrische Umwelt$$vTerrestrische Umwelt$$x0 000009587 9132_ $$0G:(DE-HGF)POF3-582$$1G:(DE-HGF)POF3-580$$2G:(DE-HGF)POF3-500$$aDE-HGF$$bKey Technologies$$lKey Technologies for the Bioeconomy$$vPlant Science$$x0 000009587 9201_ $$0I:(DE-Juel1)ICG-3-20090406$$d31.10.2010$$gICG$$kICG-3$$lPhytosphäre$$x1 000009587 970__ $$aVDB:(DE-Juel1)119508 000009587 980__ $$aVDB 000009587 980__ $$aConvertedRecord 000009587 980__ $$ajournal 000009587 980__ $$aI:(DE-Juel1)IBG-2-20101118 000009587 980__ $$aUNRESTRICTED 000009587 980__ $$aJUWEL 000009587 980__ $$aFullTexts 000009587 9801_ $$aFullTexts 000009587 981__ $$aI:(DE-Juel1)IBG-2-20101118 000009587 981__ $$aI:(DE-Juel1)ICG-3-20090406
