Global atmospheric CO{sub 2} concentrations have been increasing over the past several decades and are projected to continue increasing for several more decades. Because of the fundamental role of CO{sub 2} in the physiology of all green plants, changes in plant growth and productivity are expected. There is ample experimental evidence illustrating an increase in photosynthesis and growth with increasing CO{sub 2} concentrations. However, much of this evidence is based on short term results and optimal growth and nutrient conditions. Kramer raised the question of whether plants growing in natural environments, which are probably more often limited by water or nutrient (especially nitrogen) deficiencies than by low CO{sub 2}, will respond to rising atmospheric CO{sub 2} concentrations. This package covers one segment of the research performed to determine whether the proposed mechanism occurs with elevated CO{sub 2} concentrations
