 Abstract: We investigated the functional and structural responses of Scots pine to climate and estimated the importance of the genotype on the traits studied. We analysed C-13 isotope discrimination (Delta(13)C) of various provenances in a common garden experiment and gas exchange characteristics for provenances growing in their natural environment. No clear climatic trend was found in the foliar Delta(13)C values of common garden trees. Similar results were obtained from estimation of lambda (a largely VPD, temperature and light independent measure of intrinsic water use efficiency) from the gas exchange data. The ratio of needle mass to unit stem area and branch area to stem area increased towards south in both experiments and hence, seemed to be genetic. Trees from drier and warmer conditions seemed not to have either lower needle mass or higher intrinsic water use efficiency compared to northern latitudes. [References: 50]
