Energy and chemical contents of intensively cultured forest biomass are needed to determine the utilization potential of these cultural systems. Composite wood and bark specimens from 4-year-old trees of seven Populus hybrids were analyzed for: 0D gross heat of combustion, ash content, macronutrients, and selected chemicals. Similar analyses were conducted on segmental specimens (roots-no bark; wood and bark of 1, 2, 3, and 4 years of age; 1- to 4-year-old bark, and 4-year-old leaves) from one hybrid (NE-388). The energy potential, 0D gross heat of combustion, of the Populus biomass did not vary with parentage or plant tissue. Significant differences among the seven hybrids in macronutrient and chemical content suggest that parentage selection may influence nutrient budgets of the plantations and potential yield of chemical production from the biomass. In the segmental analyses of hybrid NE-388, substantial differences in macronutrient and chemical contents, as well as ash content, validated the need for judicious harvesting practices. 4 tables.
