“…Wood density is an important indicator for charcoal production since wood with higher densities tends to result in denser charcoal, consequently allowing for a higher gravimetric production per unit in a kiln (MOULIN et al, 2017a). Therefore, the greater the basic density, the greater the biomass stored per cubic meter (m³) (SANTOS et al, 2016).…”

This study aimed to evaluate the biomass yield, volume, and basic density of Mimosa caesalpiniifolia Benth. wood in response to planting densities in 13-year-old trees. The research was conducted in Mossoró-RN using a randomized block design with three replications. Plants obtained from seeds collected from the natural vegetation of the Caatinga in Mossoró-RN were subjected to densities of 800 (5.0 m x 2.5 m), 1600 (2.5 m x 2.5 m), 2000 (2.0 m x 2.5 m), and 4000 (1.0 m x 2.5 m) plants ha-1. The following characteristics were assessed: plant height, diameter at breast height, cross-sectional area, basal area, individual volume, stere volume, aboveground biomass, and basic wood density. The dendrometric variables showed a high correlation with planting density. For DBH and cross-sectional area, higher values were observed in the lowest planting densities. The highest values of basal area, volume (m3), stere volume, and dry biomass per hectare were found at the highest planting density. Biomass allocation showed the sequence stem>branches>leaves, regardless of the planting density evaluated. The higher densities resulted in a higher basic density of the wood. The higher planting densities proved advantageous 13 years after planting due to the higher production of dry biomass, volume (m3), and stere volume per hectare.

“…Some references indicate a small increase in density as a function of planting spacing in eucalyptus stands (Feuchard 2015, Rocha et al 2016, Moulin et al 2017, Teixeira et al 2020. However, considering the multiple uses of wood, the increase in density impacts the production and economy of the forest-based sector (Lasserre et al 2009, Pachas et al 2019.…”

“…Planting spacing is one of the main factors to be considered when planning and implementing forestry projects for the production of wood. The distance between trees represented by the useful area results in economic, silvicultural and technological implications, influencing the cost of forest production, the growth rate and age of trees, forestry practices and the quality of the wood produced (Eloy et al 2016, Rocha et al 2016, Moulin et al 2017, Brito et al 2019, Resquin et al 2019, Souza et al 2020.…”

“…Studies that report the influence of spacing on the properties of Eucalyptus wood concentrate basically on the basic density of the wood (Alcorn et al 2007, Lasserre et al 2009, Moulin et al 2017, and the knowledge on information that precisely addresses the impact of planting spacing of young trees on the anatomy and chemical composition of wood is incipient. Although the short rotation periods provide greater volumes of wood, it is essential to guarantee conditions that allow the proper establishment of the forest crop (Resquin et al 2019), and consequently, quality wood.…”

“…One of these characteristics is planting spacing, which has effect on timber production per tree, and affects dendrometric attributes that influence volume (MOULIN et al, 2017;SILVA et al, 2019). Therefore, it is essential to assess the need to develop independent equations for each planting spacing, aiming to ascertain whether the specificity of adjustments contributes significantly to error reduction, comparatively to the adjustment of a single model using all available data.…”

The aim of this study was to develop volumetric equations for tachi-branco trees (Tachigali vulgaris L. G. Silva & H. C. Lima), by assessing the effect of initial planting spacing in volume estimates, as well as developing an equation to estimate the equivalent diameter (deq). Data are from an experiment located in north Pará. The experiment was conducted with the randomized blocks design, being three blocks with six treatments each. The most used volumetric models were assessed for two distinct situations: considering each trunk as a tree and using the tree deq as independent variables in the volumetric model. The need for individual equations for initial planting spacing was tested. In addition, an equation for deq estimate was proposed. The use of deq provided more precise and accurate volumetric estimates regarding diameter at breast height. Among the models tested, the Schumacher-Hall model was selected. Through the model identity test, the equation can be used to estimate tree volume of Tachigali vulgaris, regardless of planting spacing. The equivalent diameter can be estimated via equation from minimum and maximum diameters of tree trunks. The maximum percentage differences of volume by hectare obtained with the measurement of all trunks and deq were only 5% without loss in production accuracy per unit of area
