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.
and heartwood veneers in combination with Pinus elliottii veneers.
"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.
In order to isolate fungi from sapwood
under galleries of H.
The distinction between heartwood and sapwood
was performed macroscopically by colour difference, and heartwood radius and sapwood
width were measured.

Table 1.--Mean boron acid equivalent content (%BAE) in sections cut from the bark and sapwood
of Douglas-fir log sections treated with disodium octaborate tetrahydrate (DOT) alone or DOT with glycol.
Red oak has a nearly white sapwood
, with the heartwood typically brown with a tinge of red.
