General Description: The heartwood is orange to
reddish-brown in colour and may be resinous. The growth rings are clearly
marked by the contrast between the earlywood and darker, more dense
latewood giving a coarse texture, especially in rapidly grown timber.
Southern Yellow Pine sheds its branches as it grows with the crown
generally consisting of the upper one-third of the tree. As a result,
knots are intergrown and sound with few holes or dead knots in the timber.
Since, with increasing frequency the trees are grown and harvested on
short rotation, saw-logs are comparatively small with sapwood
predominating. The weight varies between 537 and 626 kg/m3 (34 -
39lb/ft3); specific gravity 0.54 to 0.63. |
