AB Eight poplar genotypes grown in a short rotation forest plantation established in an acidsoil in South Europe were sampled at the age of 7 years to determine the energy properties regardingthermochemical conversion. The goal was to address the effect of selection of genotypes or shoot sizeat harvest on the energy quality of biomass. Between 34 and 50 biomass samples were obtained foreach genotype: three disks were systematically sampled along the stem and were pooled togetherwith a subsample of leafless branches representative of the biomass share of this component. Severalenergy properties were determined: higher calorific value, net calorific value, fresh moisture content,basic density, ash, volatile matter, fixed carbon content and elemental composition. Genotype had asignificant effect on most of these properties, and the balsam genotypes displayed superior qualityparameters and also higher biomass yield than the Euramerican genotypes. As a covariate, shootbasal diameter had a significant effect on the moisture content, basic density, ash content and on theconcentrations of the elements N, K, Ca, Mg, S, Na and C. It was concluded that genotypes with lownutrient requirements planted at low density (<8000 cuttings ha−1) and harvested at a long enoughrotation (7 years) produce good yields and high chip quality. Poplar short rotation crops can be grownto produce chips of A2 quality for non-industrial heating use (according to UNE-EN ISO 17225-4),able to be combusted in domestic thermal facilities of <1 MWth power.
