The two main parts of a log, sapwood and heartwood, have different properties. With regard to
utilization in the wood industry, the latter is of great importance because of its higher durability
and better mechanical properties. In case of wood species with colored heartwood, this fact is
considered through the removal of the sapwood. This is especially true for oak, which is one of the
most valuable dominant hardwood species in Hungary that prefers full sunlight and has a wide
range of utilization. More than one third
of the domestic wood volume consists of oak species. The
heartwood formation process of oak – just like in any other wood species – is influenced by many
factors. Perhaps the most important is the genetic features of the tree, namely the wood species.
There are several external determinative factors,
however, like the growing conditions and ecological
circumstances (geographical situation, climate, site, hydrology, etc.). Unfortunately, the effect of the
circumstances is usually not taken in account despite its high importance. In terms of the quality
improvement of oak stands, the examination of the relationship between heartwood-sapwood ratio
and environmental factors can be a new approa
ch. Increasing heartwood ratio, among numerous
other benefits, primarily results in economic asset, therefore the investigation of the heartwood
formation rate cannot be neglected. To confirm this statement, the present study demonstrates that
the geographic situation of forest stands is an impor
tant factor in the heartwood formation process.
