“…The measured compressive strength ranged from 2.6 to 5.6 MPa, with an average of 4.2 MPa. These results are comparable with similar values reported in the literature for the same species (McKimm 1985) and for other species of the same Eucalyptus genus (Nogueira et al 2018a). On the other hand, the values measured in this study were similar to those reported by Lobão et al (2004) for Eucalyptus grandis (4.9 MPa), and the results obtained by Awan et al (2012) for Eucalyptus camaldulensis (5.5 MPa).…”

“…Moreover, there are many studies with E. nitens in which the basic density is measured in the radial and longitudinal directions with reporting values from 400 to 550 kg/m 3 (Downes et al 1997;Evans et al 2000;Shelbourne et al 2002;Leandro et al 2008). McKimm (1985) studied the variation of properties in 8.5-year-old E. nitens and concluded that in general the strength properties are lower than in wood from adult E. nitens trees, but the values are comparable with those of Pinus radiata, showing the wood materials would be suitable for structural use. This was also confirmed by Yang and Waugh's research (1996), which considered the properties of 15-to 29-year-old plantation trees and the results suggest that wood from that type of plantation with those properties and characteristics can be used for producing sawn lumber for structural applications.…”

The objective of this study was to measure compressive strength properties perpendicular to the fiber of green Eucalyptus nitens specimens. The data was measured for clear 50 × 50 × 150 mm specimens obtained from 17-year-old trees that were harvested at the Ñuble region in Chile, and the data comprised modulus of elasticity (Ec), compressive strength (ƒc), basic density, initial moisture content, and some anatomical characteristics of the wood. The experimental design emphasized the influence of the radial position of the wood within the logs (defined as inner-wood, middle-wood, and outer-wood) on the measurements, and the results showed that the modulus of elasticity, compressive strength, and the basic density all increased from core to bark. The compressive strength of outer-wood showed a strong and positive relation with the basic density. Cell wall thickness and wall cell area showed a significant positive correlation with compressive strength.

“…With some exceptions (Washusen 2001;Waugh and Yang 1994), E. nitens sawmilling and processing studies have indicated that drying defects can substantially reduce the recovery of appearance-grade sawn timber from plantations (Haslett 1988;Lausberg et al 1995;McKenzie et al 2003b;McKimm et al 1988; Reid and Washusen 2001;Shelbourne et al 2002;Valencia 2008). These drying defects, including cupping, face checking (i.e.…”

Eucalyptus nitens plantations are generally established for pulpwood production but an increasing area is being managed for solid wood. Genetic variation in, and correlations among, three Kraft pulpwood traits (diameter at breast height, basic density and near-infrared-predicted cellulose content) and three 12-mm wood-core shrinkage traits (recoverable collapse, net shrinkage and gross shrinkage) were examined, utilising data from two 9-year-old firstgeneration progeny trials in Tasmania. These trials contained approximately 400 open-pollinated families (over 100 of which were sampled for wood properties) representing three central-Victorian E. nitens races. Significant genetic variation at the race and/or within-race level was identified in all traits. Within races, relative levels of additive genetic variation were higher for shrinkage traits, although narrowsense heritabilities were lower and the expression of genetic variation less stable across sites than for other wood property traits. Heterogeneous intertrait genetic correlations were identified across sites between growth and some wood property traits. However, where significant, genetic correlations indicated that within-race selection for growth would adversely affect core basic density and all core shrinkage traits. Furthermore, results based on cores suggested that within-race selection for higher basic density would favourably impact on cellulose content and collapse but selection for either higher basic density or cellulose content would adversely affect net shrinkage. Most within-race genetic variation in gross shrinkage appeared to be due to genetic variation in collapse. The implications of these results for sawn timber breeding will depend on the strength of genetic correlations between core traits and rotation-age objective traits and objective trait economic weights.

“…They also found a significant positive association of clear wood MoE with the basic density. The strong correlations between basic density with clear wood MoE have been reported for E. globulus and E. nitens (McKimm et al 1988;Yang 1997;Chauhan and Walker 2004). Since the green density was more or less uniform across the clones, nearly 97% variation in MoE is explained by the acoustic velocity measured in logs.…”
