Abstract:

Estimates of terrestrial biomass depend critically on reliable information about the specific gravity of the wood of forest trees. The study reported on here was carried out in the southern Peruvian Amazon and involved collection of wood samples from trees (70 spp.) in intact forest stands. Results demonstrate the high degree of variability in specific gravity (ovendry weight/green volume) in trees at single locations. Three forest types (swamp, high terrace forest with alluvial soil, and sandy-soil forest) had values close to the average reported for tropical forest woods (.69). Two early suc

Abstract:

The effect of growth rate on the specific gravity of East-Liaoning oak (Quercusliaotungensis Koidz.) wood was studied and statistically compared with the effect of age (ring number from the pith). Results revealed that age is a decisive factor in controlling the specific gravity of wood, while effect of growth rate on specific gravity is statistically less important. Furthermore, the effect of growth rate varies with ring width range, age, and position within one growth ring (earlywood, latewood, or the whole ring). Within narrower ring widths, specific gravity increases rapidly with increasin

Ten trees were selected from each stand and two stands were chosen from each location. Univariate analyses of variance indicated that growth rate and latewood of juvenile wood varied significantly in various locations, stands, and trees at the α = 0.01 level of significance.

Local wisdom in utilizing swamp soil and water to improve the quality of gelam wood in Central Kalimantan becomes an interesting phenomenon. Improving the quality of wood can economize on the use of wood, which in turn preserves the forests in peat swamp lands. Gelam (Melaleuca sp.) woods that are mostly found in peat swamp forests can be used as piles/stakes in swamp soil, and they are durable for decades. The general objective of this study was to provide a scientific explanation of the effect of peat swamp soil and water on improving the quality of gelam wood either in barked and barkless c

Abstract Two 8-year-old grafted ramets from 12 lodgepole pine (Pinus contorta var. latifolia) ortets (wild stand parent trees) were sampled at each of three sites and were assessed for specific gravity with small diameter cores. The broad-sense heritability estimate from the analysis of variance was 0.62, but estimates derived by regressing clone means from ramets on ortet values were 0.49 and 0.54 for juvenile and mature wood, respectively. This relatively high repeatability for specific gravity suggests wild-stand ortet values may be useful for identifying low specific gravity clones in seed

Abstract:

Larch bark is an interesting resource for the production of insulation panels. As it consists of a sugar-rich inner bark and an outer bark containing more durable components, there is the requirement to separate these compartments. Additionally, bark is often mixed with wooden pieces after industrial debarking processes. In this study, the wet density, dry density, and specific gravity of wood, whole bark, and inner and outer bark are investigated using the pycnometer method, which has been proven to be adequate for the volume measurement of irregularly shaped, light objects such as bark flake

Abstract There has been increasing interest in using the plantation-grown white pine resource in Ohio. Potential uses include posts, poles, sawlogs, and pulp fiber. Estimates of specific gravity and weight prediction equations are needed to use this material effectively. Specific gravity or density is the simplest and most useful index to the suitability of wood for many important uses. It is a particularly important factor in the manufacture of pulp and paper because specific gravity largely determines the dry pulp yield from a given volume of wood. It is also directly related to strength and

Abstract:

AbstractVariations in the growth site of trees have influence on the internal structure of the trunk. Considering this fact, this study investigated influence of the characteristics of the growth site on wood specific gravity of two clones of Eucalyptus urophyllax Eucalyptus grandis, approximately six years old, growing in different altitudes and topographies. Furthemore, two methods of sampling of the wood specific gravity were studied, for comparison purpose. Results showed that wood specific gravity underwent variations between growth conditions andtrends in wood specific gravity variations

Abstract:

Specific gravity, moisture content of the wood, and stem bark percentages in 1-year-old shoots of 20 Salix (L.) clones originating from natural and artificial stands in Sweden were measured for 3 years. Clones were classified into three groups with high, medium, and low specific gravity. Ranking stability for specific gravity was high. Moisture content and bark percentage fluctuated considerably from one year to another but showed a slight increase from the high to the medium and low specific gravity groups.

Abstract:

The habit, specific gravity and wood anatomy of 43 Afromontane and 50 Bushveld species from Swaziland are compared, using qualitative features from SEM photographs of charred samples. Woods with solitary vessels, scalariform perforation plates and fibres with distinctly bordered pits are more common in the Afromontane species, whereas homocellular rays and prismatic crystals of calcium oxalate are more common in woods from the Bushveld.

Abstract:

The Tambopata region of the southern Peruvian Amazon supports a high diversity of both woody plants and forest types. Woods collected from low riverside vegetation, floodplain forest, clay-soil forest on an upper terrace, sandy-soil forest, and swamp forest provide an opportunity to test for significant differences in quantitative anatomical characters among forest types. Vessel-element length in floodplain-forest trees is significantly greater than in the other forest types. Specific gravity is lower in the two early-successional associations (low riverine forest and mature floodplain forest)

Abstract:

To be able to make accurate estimates of the carbon stocks present in the world's tropical forests, there is a growing need for accurate tree biomass estimations on large spatial scales (Chave et al. 2004, Cummings et al. 2002, Nascimento & Laurance 2004). Wood-specific gravity forms an important component of these biomass estimations (Baker et al. 2004, Magcale-Macandog 2004, Nogueira et al. 2005). Even though Chave et al. (2004) found that the most important source of error in above-ground biomass estimation (AGB) is currently related to the choice of allometric model, Baker et al. (2004

Abstract:

Selected anatomical characteristics and wood specific gravity of 8-year old teak trees protected from insect defoliation were compared with those from an unprotected population. Trees during the protection period of four years showed considerable increase in ring width (growth rate). Although latewood width was more closely correlated with ring width than earlywood width, no significant differences were found in specific gravity, cell wall percentage and diameter and percentage of vessels, probably due to juvenility. Furthermore, no intrinsic relationship could be established between the insec

Abstract:

Compression tests and specific gravity analyses were conducted to investigate the impacts of growth suppression and growth release on wood quality in yellow-poplar ( Liriodendron tulipifera L.). Growth ring widths in 23 increment cores were determined and the years of minimum suppression and maximum release were identified based on a modified radial growth averaging technique. Three specimens (1 mm × 1 mm × 4 mm) from both minimum suppression and maximum release years were prepared from each increment core. Data analysis using paired-samples t tests revealed that the mean ultimate crushing str

Abstract:

Increases in wood specific gravity (SG) with distance from pith are associated with the growth strategies of trees and their environments. In the present study, radial gradients in SG were analysed for 20 species from nutrient-rich whitewater floodplains (várzea), including seven pioneer species, and for 15 species from nutrient-poor blackwater floodplains (igapó) in Central Amazonia. Average SG increased from pith to bark by 12% in the species from igapó, compared to 16% in the nonpioneers and 35% in the pioneers from várzea. The increases lie in the range of tropical dry forests. SG variatio
