“…In reforesting of Pinus taeda established in the region of Jaguariaíva-PR, on the spacing of 2.5 x 1.2 m; 2.5 x 2.0 m; 2.5 x 2.8 m; 2.5 x 3.6 m and 2.5 x 4.4 m, it was observed an effect on the planting density over the diameter, exceptionally at more advanced ages and on larger spacing (SANQUETA et al, 2003). In established planting with hybrids of Eucalyptus camaldulensis Dehn x Eucalyptus urophylla S.T.…”

This study aimed to assess the initial development of Eucalyptus benthamii implanted in four different spacing. The experiment was conducted in random block design, using the following spacing: 2x3, 3x3, 3x4 and 4x4. We used height and diameter at breast heights (DBH) data collected at the ages of 2 and 3 years to assess the linear correlation between the variables, annual height and diameter increase, and the volumetric production at 3 years old. The results did not show significant difference of individual height and volume in the performed assessments. However, it was observed a higher diameter increment according to higher vital area availability. The highest productivity rate was of 66.55 m³ ha-1 , registered in a 2x3 spacing between plants, while in the biggest spacing adopted (4x4) the productivity was of only 31.61 m³ ha-1 , at three years old. It was concluded that there's influence of the spacing on the dendrometric variables, mainly in diameter and volume.

“…The DBH results were therefore linked to the spatial arrangement, noting that the single row arrangement, which provides the greatest useable area per plant, provided the highest DBH values. Often, the greater the area available for plant growth, the greater will be the stem diameter (Berger et al, 2002;Sanquetta et al, 2003;Lima, 2010). The increase in the useable area per plant results in greater availability of environmental resources such as water, light and nutrients.…”

This research evaluated the influence of different spatial arrangements on the growth of three Eucalyptus clones as well as the characteristics that influence the quality of the timber. The experiment was carried out at Embrapa-Beef Cattle station, Campo Grande city, Mato Grosso do Sul State, Brazil. The design was in randomized blocks in a factorial scheme (3 × 3) with plots subdivided by time and four repetitions. Three clones of Eucalyptus were used (Urocam VM1, Grancam 1277 and Urograndis I144), and there were three spatial arrangements (single, double and triple row). At 20 and 32 months after planting, the variables, total plant height, diameter at breast height (DBH), volume of timber per tree, volume of timber per hectare, straightness and forking, and cylindricity were evaluated. The spatial arrangements influenced the behavior of the genetic material, and the greatest tree heights were observed in the triple row arrangements. The single row arrangement provided greater gains in DBH. The Grancam clone stood out from the others in the characteristics of straightness and forking, independent of the spatial arrangement and time of evaluation. It was concluded that the volume of timber per tree and the volume of timber per hectare were associated with the planting density, low density results in lower volume.

“…Husch et al (1972) stated that each species and each tree may need a period of time to complete its life cycle. Changes in forest growth conditions affect the amount of produced timber, dominance, mortality rate, and growth stagnation age (Sanquetta et al, 2003).…”

Do the Growing Conditions of Trees Influence the Wood Properties?

Currently, there is a little and sparse information about how the growing conditions influence the spatial variation of wood along the stem. Thus, the aim of this study was to compile the knowledge from literature in a manuscript for better understanding to what extent the growing conditions influence the spatial variation of wood properties in Eucalyptus plantations. The wood characteristics may present variations in their properties and can be caused by both genetic and environmental factors. However, how genetic and environmental factor acts on wood variation along the trunk is still unclear. Another point is that even with new genetic breeding programs, the mechanical properties of wood have not been considered in these programs, since the selection of new material is always based on the growing rate, cellulose and lignin content and wood density.
