“…Fibre length has been reported to show negligible correlation with density (Dean et al 2002) and this was the observation in this study. In contrast, fibre wall thickness and lumen diameter were the more influential factors on the wood density and similar findings were reported by Qumruzzaman et al (2012), Kiaei (2011) and Maharani and Andrian (2015).…”

Adhesion capability of timbers varies greatly depending on anatomical structure and origin of the species. Unlike temperate hardwood, tropical hardwood has slightly different anatomical structure due to the influence of growing season. This study evaluates the anatomical structure of three tropical hardwood species of different densities, namely, batai, sesendok and kedondong and their effects on surface roughness and wettability. Rubberwood was used as control. The fibre length, wall thickness, lumen diameter, fibre diameter, vessel diameter, density, surface roughness and wettability were determined according to the relevant standards. The study showed that the strength of the relationship varied according to species and anatomical structure. Very good correlations (r 2 > 0.8) were obtained between the anatomical characteristics and density, surface roughness and surface wettability for batai, sesendok, kedondong and rubberwood. Rubberwood behaved differently than the three species while batai and sesendok were quite similar. Density and surface roughness were highly influenced by fibre wall and cell wall thicknesses while contact angle, by fibre length, fibre diameter, fibre wall thickness and lumen diameter. Surface wettability of the wood was influenced mainly by fibre wall thickness and surface roughness.

“…There was a significantly positive relationship between wood fiber cell wall thickness and SG (r = 0,78 in earlywood, r = 0,79 in latewood) while wood fiber lumen diameter was negatively correlated with SG. The present results are in line with those of Ishiguri et al (2009) and Chowdhury et al (2012) for Paraserianthes falcataria and C. equisetifolia, respectively. Table 3: Pearson's correlation coefficients between anatomical characteristics and wood specific gravity in Melia azedarach.…”

“…In this study, as shown in Table 3, a significant positive correlation was found between vessel lumen diameter and SG both in early and latewood (Pearson's correlation coefficient r = 0,79 in earlywood, r = 0,62 in latewood). While contradictory to those reported by Savidge (2003) a positive correlation between vessel lumen diameter and wood density was also found in Casuarina equisetifolia (Chowdhury et al 2012). A probable explanation is that average vessel lumen diameter increased, while vessel frequency decreased from the pith to bark.…”

The radial variation in cell morphology of ten-year-old Melia azedarach trees planted in northern Vietnam was experimentally investigated. The earlywood fiber lumen diameter and latewood fiber lumen diameter were almost unchanged from pith to 6th ring before significantly decreasing and remaining constant from 7th ring outwards. In contrast, fiber cell wall thickness in both earlywood and latewood increased from pith to 7th ring before becoming stable towards the bark. The maturation age of earlywood vessel lumen diameter estimated by segmented regression analysis indicated that wood of the Melia azedarach could be classified into core wood and outer wood, and the boundary between core and outer wood may be located at 7th ring from pith. This should be taken into account in wood processing using M. azedarach grown in northern Vietnam.

“…Thus, the best use of the material also depends on these values (Usta and Guray 1998;Logsdon 1999;Boldin et al 2008;Lubas et al 2008;Quartaroli et al 2010;Chowdhury et al 2012;Moore et al 2015;Kotlarewski et al 2016).…”

Wood is a material widely used in various sectors of construction, such as in structures and building components. The volume of wood extracted from tropical forests has reached a considerable amount, and this wood is marketed with popular names without prior characterization. Wood density is an easy property to measure, and its use as an estimator of other properties is very common in this sector. This study investigated the possibility of the estimation of important quantities in dimensional stability of Brazilian tropical woods by using the density at 12% moisture content, anhydrous density, and basic density. Testing the ability to estimate radial, axial, tangential, and volumetric shrinkage, anisotropy coefficient, coefficient of volumetric rate of volumetric shrinkage, as well as the rate of volumetric swelling using the densities above, with linear, exponential, geometric, and logarithmic models, the best determination coefficient was: R 2 = 19.58%. The results were, in summary, that the variable density was not a good estimator of the dimensional stability of the wood.
