Article Synopsis
- Intra-annual variations of carbon stable isotope ratios (δ13C) in tree compartments can indicate plant carbon source-sink dynamics on a weekly basis, but tracking these variations has been challenging due to the complexity of tree ring development.
- A new method was developed to monitor weekly δ13C variability in the cambium-xylem continuum of black spruce trees over multiple growing seasons in Quebec, allowing researchers to create δ13C series for both growing cambium and developing xylem cellulose.
- Strong positive correlations between δ13C values suggest a consistent supply of fresh carbon to support tree growth, while trends in δ13C indicate potential shifts in carbon allocation strategies related to environmental factors such as seasonal light changes.
