Growth Processes of Norway Spruce in Elevated CO2 Concentrationted in 1982. The trees were exposed to the following three treatments: four OTC’s with ambient atmospheric CO. (350 ppm), four OTCs with doubled CO. (700 ppm) and four freely growing trees. A destructive analysis of all sample trees was carried out in 1995. The 15-year-old trees did not show signifi

Changes of the Primary Photosynthetic Reactions of Norway Spruce under Elevated CO2eading to an increased sensitivity of the photosynthetic apparatus to high irradiance. Therefore, the effects of elevated CO. on the light reactions of photosynthesis of Norway spruce during long-term growth in open chambers at ambient and elevated CO. concentration were studied. A significant depre

Experimental facilities included four open top chambers (OTC), representing two replicated CO. treatments, ambient (ca. 350 μmol mol., the current background level) and elevated CO.

Effects of High CO2 and N Fertilization on Scots Pine Needleseld-grown Scots pine were studied in a branch-bag experiment. Decreased Rubisco content and increased C/N in nonfertilized trees indicated acclimation response to elevated CO. . Photosynthetic rates measured at ambient CO. were maintained. No acclimation response to high CO. was observed in fertiliz
