Abstract

Toestablishagermplasmevaluationmethodofrapeseedseedlingonnitrogen(N)efficiency,hydroponicassaywasperformedusing162rapeseedlinesunder2nitrogenlevels(control,9500μmol/L;LN:lowN treatment,237.5μmol/L)atseedlingstage.Biologicalcharacteristics,includingNefficiencyandgenotypicdifferencesamongdifferentrapeseedlineswereinvestigatedin2015and2016.Resultsshowedsignificantdifferencesbetween2treatmentsonbiomass,mainrootlength,lateralrootlength,root-shootratio,Naccumulation,Nuptakeanduseefficiency.Amongthem,seedlingbiomasswashighlypositivelycorrelatedwithNaccumulation,Nutilizationindex,andNuptakeefficiency.Itwaspositivelycorrelatedwithlateralrootlength.Significantincreaseinmainrootlength,lateralrootlengthandroottoshootratiowerefoundinLN-treatment.Additionally,apositivecorrelationwasfoundbetweenroottoshootratioandlateralrootlengthunderLN.ItwassuggestedthatfacilitatinglateralrootgrowthmightbeanimportantwayforrapeseedrespondtoLNstress.ResultalsoshowedthatNuptakeefficiencyhadgreaterinfluenceonbiomassproductionthanthatofNuseefficiency.BiomassshowedhighlysignificantcorrelationwithNuptakeefficiency.Lateralrootlength,NaccumulationandNutilizationindexalsoexhibitedsignificantcorrelationwithNuptakeefficiency.Therefore,biomasswaschosentobeamajorindicatorforevaluatingrapeseedNefficiencyatseedlingstage.Andlateralrootlength,NaccumulationandNutilizationindexmightbeassistantindexes.Thus162rapeseedlineswerefurtherclassifiedinto3typesbasedonaveragebiomassunder2Nlevels.Specifically,23ofthemweredouble-highNefficiencyrapeseedgenotypes,28weredouble-lowNefficiencyrapeseedgenotypes,and111werethemiddletype.Furtheranalysisrevealedthatbiomass,NaccumulationandNutilizationindexofdouble-highNefficiencygenotypeswereindeedgreaterthanthoseofdouble-lowNefficiencygenotypes.Moreover,theyweremoreefficientinNuptakeandaccumulationunderLNstress.TheresultssuggestedthatNefficiencyevaluationofrapeseedbyseedlingbiomasswasreliable.
