To verify the significance of differences between the individual analyzed parameters, analysis of variance and Tukey's multiple comparison test (P < 0.05) were performed using the two wood tissues (heartwood and sapwood) and the different chemical components in each tree as criteria.
volvatus is restricted to the sapwood, it may play a role in promoting wood boring insects such as flat-headed wood borers (Coleoptera: Buprestidae), round-headed wood borers (Coleoptera: Cerambycidae), and other under-bark inhabiting insects (Borden and McClaren 1970, 1972), which provide further food resources for bark-foraging birds.
In adult trees, the sapwood is approximately 5.0 cm thick (Lemmens, 2008), and the flux density in the radial direction may vary, as observed in C.
The objectives of this study were: (a) to examine the variations of wood density and mechanical strength properties (MOE and MOR) along longitudinal position, (b) to compare wood properties between heartwood and sapwood, and (c) to determine the relationship between wood density and mechanical properties in Persian silk wood (Albizzia julibrissin).
"It is the mockingbird of wood with sapwood that resembles ash, heartwood that looks like white oak and pecky wood that looks like elm or even chestnut.
The distinction between heartwood and sapwood was performed macroscopically by colour difference, and heartwood radius and sapwood width were measured.
