Comparison of stable carbon isotope ratios in the whole wood, cellulose and lignin of Oak tree-rings.

The resulting time series demonstrate a very high degree of coherence, with N13C of cellulose isotopically enriched by approximately 3xcompared to N13C of lignin. The N13C values of all three components are influenced by the climate of July and August. Modern whole wood retains the strongest climate signal, perhaps because its composition is closest to that of leaf sugars. In sub-fossil wood there is no evidence that differential decay leads to fractionation of carbon within either cellulose or lignin, but differential decay can alter the cellulose to lignin ratio.297515 bytesapplication/pdfenCopyright: 2003 Elsevier Science BVStable carbon IsotopesClimate signalsTree-ringsDendroclimatologiesCellulosesLigninsArticleLoader, N., Robertson, I., & McCarroll, D.
