The assumption that biomass allocation, energy allocation, and nutrient element allocation are equivalent for studies involving ecological-strategy analysis in plants was tested. The results for the semelparous Verbascum thapsus and 5 iteroparous Solidago spp. [S. nemoralis, S. rugosa, S. caradensis, S. flexicaulis, S. caesia] show that the mineral elements examined are allocated differently than biomass. Thus, in estimating the allocation strategy of plants within a population, biomass allocation does not reflect nutrient allocation. There are significant nutrient .times. population interactions, which means that between-population trends in biomass allocation do not reflect qualitative trends in mineral element allocation. This study does not identify a given mineral element, biomass, or energy as the best measure of resource allocation patterns. Results with Solidago show strong correlation between biomass allocation and energy allocation. This reemphasizes Hickman and Pitelka''s (1975) conclusion that calorimetry is not necessary to determine energy allocation patterns within populations in plants with primarily carbohydrate seed reserves. There was an overall lack of correlation between soil nutrients and the chemical composition of Solidago plant organs or whole plants.
