Summary

The effects of elevated carbon dioxide concentration ([CO2]) on the structure of xylem cells in trees have not yet been clarified, in spite of the importance of woody plants as large, long-term carbon sinks. We review recent studies that have investigated how elevated [CO2] affects growth ring features. In general, elevated [CO2] enhances radial growth, especially when sufficient nutrients are supplied. The mean density of growth rings also increased but sometimes it decreased or remained unchanged, depending on the extent of cell division, cell expansion and cell wall thickening under elevated [CO2].
