Respiration of pine crown under elevated CO2 and temperature
Long-term acclimation to elevated CO2 and temperature of respiration by the foliage in the crown of Scots pine trees is assessed by Wang et al. (pp. 325-335). Changed respiration parameters for individual leaves made only a small contribution to the annual crown respiration compared with the increased total foliage area. Effects of changes in crown architecture and nitrogen distribution, caused by treatments, on the daily and annual course of crown respiration are highlighted.
