【 摘 要 】

Alnusglutinosa(Betulaceae)hasawidespreaddistributionintheCentralBlackSeaRegionofTurkey.Inthisstudy,annualnitrogen(N)andphosphorus(P)andfoliarresorptionefficiencyandproficiencywereinvestigatedinA.glutinosa.NandPconcentrationsweredecreasedinsenescentleaves.StatisticallysignificantdifferenceswerefoundinPconcentrationswhiletherewerenofoundsignificantdifferencesinNconcentrationswithrespecttomonths.AnegativecorrelationwasobtainedbetweenSLAandLMA,SLAandNconcentrations.However,thereweresignificantcorrelationsbetweenLMAandNconcentrations.NandPresorptionefficiency(NRE,PRE)andproficiency(NRP,PRP)valueswerehighascomparedtotheotherdeciduousspecies.TheseresultsindicateefficientinternalcyclingofnutrientsespeciallyPinA.glutinosa.
