Promising Amazonia species for forest energy crops require further investigation into how silviculture affects wood quality. This study sought to investigate how planting spacing and stem type (forked and non-forked) affect the basic wood density, X-ray density, and heartwood development of Tachigali vulgaris in a homogeneous plantation in Amazonia. The experiment was established with initial planting spacings of 3.0 × 1.5 m, 3.0 × 2.0 m, 3.0 × 2.5 m, 3.0 × 3.0 m, 3.0 × 3.5 m, and 3.0 × 4.0 m. 102-month-old trees were harvested for the work. Disks sampled along the stem height were tested for wood basic density and density measured by X-ray densitometry (air-dry density by growth ring) analyses. Disks obtained at the 1.3 m height were photographed and submitted to image manipulation for heartwood/sapwood analysis. The lowest average wood density was 0.512 g cm−3 in the 3.0 × 1.5 m spacing, and the highest was 0.538 g cm−3 in the 3.0 × 4.0 m spacing. Among non-forked trees, 66% had medium-density (≥ 0.500 g cm−3) and 34% low-density (< 0.500 g cm−3) wood. In contrast, forked trees had only 55% of trees with medium-density wood. The X-ray density profiles reduced from 0.713 to 0.582 g cm−3 in the increasing longitudinal direction and from 0.393 to 0.973 g cm−3 in the radial direction. Forking did not influence the heartwood proportion (60.03–61.54%). The 3.0 × 3.0 m spacing favored the wood quality concerning density class and variability, while the widest spacings improved heartwood formation. The forking increases the chances of low-density wood and its variations along the stem. Thus, future genetic studies should focus on this phenomenon to increase the productivity of Tachigali vulgaris energy forests.
