The objective of this research was to investigate the acclimation phenomena involved in plants as they adjust to a CO{sub 2} enriched atmosphere. Plants were grown under various CO{sub 2} concentrations in the controlled chambers of the Duke University Phytotron. Soil nutrients, irradiance, temperature, soil water, and atmospheric relative humidity were controlled. Photosynthesis, leaf structure, leaf biomass of photosynthetic leaves or leaflets and of growth points that are not assimilating CO{sub 2} were measured to determine contributions of carbon source tissues to sink tissues. Export and import rates following movement of plants into atmospheres of higher carbon dioxide concentration were specifically examined
