Abstract

Like tree growth, dormant-season carbon storage is an important, integrative measure of tree health. Carbon is stored throughout trees in the form of carbohydrates for later use as an energy resource and substrate for synthetic products (Kozlowski et al. 1991). Trees rely on carbon fixed during the latter part of the growing season, and stored through the winter, to produce new organs for gathering light, water, and nutrients (Gholz and Cropper 1991; Kozlowski et al. 1991). Effects of altered throughfall levels leading to changes in carbon-exchange rates should be cumulative over time (Chapin et al. 1990), resulting in either accumulation or degradation of stored nonstructural carbohydrate pools in the wetter or drier environments, respectively. (1987) and (1975) have shown evidence of stress-induced carbohydrate reductions in Quercus. Stored carbohydrate concentrations of stems are typically similar to that of coarse roots, with bothtissues responding similarly to environmental changes. However, given that stems are much more easily accessible, they are most often sampled to assess carbon storage.
