Modeling thinning effects on ring width distribution and wood specific gravity of loblolly pine (Pinus taeda L.)
… for thinning effects on growth rate and wood quality requires a clear understanding and quantification of these effects. In this regard, four basic interrelated issues were addressed in this study: 1) thinning effects on ring specific gravity 2) thinning effects on ring width distribution …

Strength Properties of Juvenile and Mature Wood of Twelve Families of Loblolly Pine (Pinus Taeda L.)
<p>The wood mechanical properties of progeny from twelve open-pollinated parent trees were examined. Six families were from parents which had high wood specific gravity and six were from parents which had low wood specific gravity. Thirty-two-year-old trees, that had been planted at Many, …

Anatomical and phenological Variation of Liquidambar Styraciflua L. Under Controlled Environmental Conditions
… of variation in fiber tracheid length, vood specific gravity, and time of apical bud formation existed vithin two populations of Liquidambar styraciflua L. from south central Kentucky. The variation exhibited by these populations may be attributed to the self-sterility of Liquidaribar and the …

Withdrawal and combined load capacity of threaded fastener wood joints
… were tested. A multiplicative model containing wood specific gravity and the wood volume contained within the fastener threads provided very accurate predictions of withdrawal strength. A second study objective was to assess the accuracy of existing design criteria for threaded fastener joints …

Effect of Minimum Suppression and Maximum Release Years on Compression Parallel to Grain Strength and Specific Gravity for Small-sized Yellow-poplar (Liriodendron tulipifera L.) Specimens
… that there is little or no relationship between specific gravity and ring width or growth rate in yellow-poplar (Liriodendron tulipifera L.). Because most mechanical properties of wood are also closely related to specific gravity, it would thus be of interest to learn how minimum suppression and …
