We studied the effects of elevated CO2 and elevated temperature on photosynthesis and composition of Scots pine needles during three years of treatments, started in August 1996. CO2 and temperature were elevated day- and year- round in closed-top chambers, which were constructed around naturally regenerated Scots pine trees growing at a nitrogen poor site. Our aim was to study, whether there is photosynthetic acclimation during three years of growth at elevated CO2 and elevated temperature in Scots pine, and whether acclimation response is connected to the aging of the needles
