摘要：

We report the carbon-13 and oxygen-18 isotope ratios in cellulose from the early and late wood of pedunculate oak (Quercus robur L.). The delta(13)C value of the early wood correlates best with that of the late wood of the previous year, The delta(18)O value of the early wood correlates best with that of the late wood of the same year. We suggest that a biochemical explanation of these data is that there is a rapid cycle between hexose monophosphates and triose phosphates in oak stem tissue during cellulose synthesis. Evidence in support of this explanation is provided by the intramolecular distribution of C-14 in labelled fructose extracted from cores of wood that had been supplied with [1-C-14]- and [6-C-14]glucose.
