Abstract
ⶠFertilization increased growth of stem-wood but decreased root starch concentrations-likely because they were consumed by growth related processes. ⶠRoot starch concentrations consistently declined with increasing sapwood area, diameter at breast height, height-to-live-crown, and cambial surface area. Thus, larger trees had consistently lower starch reserves than smaller trees. ⶠVigor index was a poor predictor of carbohydrate reserves when tree size and resource availability varied from site to site. ⶠVariables that reflect both growth and maintenance sinks are more informative predictors of carbohydrate reserves than growth variables on their own.
