<meta content="Wounding caused by certain silvicultural practices such as pruning and thinning can facilitate the development of wood decay. In plantation
trees grown for the purpose of timber production, wood decay commonly develops from dead branches and is usually confined into the mature
portion of wood than in the sound sapwood. To better predict the susceptibility (or resistance) of sapwood to decay in different wound locations,
this study compared the influence of stem with branch wounding on decay extent in plantation Eucalyptus globulus and Eucalyptus nitens in
Tasmania (Australia) after summer wounding and artificial inoculation with two white rot decay fungi. The amount of sapwood discoloration and
decay, as well as the amount of total phenols extracted from the reaction zone (a dark colored zone produced by the accumulation of phenolics)
were assessed after tree felling (13 months).
In both Eucalyptus spp., greater sapwood discoloration and decay developed from stem wounds than branch wounds. Sapwood discoloration
and decay extended further in the axial than radial or tangential wood alignments. Fungal isolations showed that wounds challenged with the white
rot decay fungi Acanthophysium sparsum and an unidentified white rot fungus always developed significantly greater sapwood discoloration and
decay than the control treatment, regardless of wood alignment. In unwounded parts of the tree, total phenols were 4.7- and 6.3-fold higher in the
branch sapwood compared to stem sapwood in E. globulus and E. nitens, respectively. The higher inherent level of total phenols in the branch
sapwood may partly explain why less dysfunction resulted from the inoculation of branches compared to stems. Overall, E. globulus developed
smaller columns of discoloration and decay than E. nitens." name="eprints.abstract" />

In plantation
trees grown for the purpose of timber production, wood decay commonly develops from dead branches and is usually confined into the mature
portion of wood than in the sound sapwood. To better predict the susceptibility (or resistance) of sapwood to decay in different wound locations,
this study compared the influence of stem with branch wounding on decay extent in plantation Eucalyptus globulus and Eucalyptus nitens in
Tasmania (Australia) after summer wounding and artificial inoculation with two white rot decay fungi. The amount of sapwood discoloration and
decay, as well as the amount of total phenols extracted from the reaction zone (a dark colored zone produced by the accumulation of phenolics)
were assessed after tree felling (13 months).
In both Eucalyptus spp., greater sapwood discoloration and decay developed from stem wounds than branch wounds. Sapwood discoloration
and decay extended further in the axial than radial or tangential wood alignments. Fungal isolations showed that wounds challenged with the white
rot decay fungi Acanthophysium sparsum and an unidentified white rot fungus always developed significantly greater sapwood discoloration and
decay than the control treatment, regardless of wood alignment. In unwounded parts of the tree, total phenols were 4.7- and 6.3-fold higher in the
branch sapwood compared to stem sapwood in E. globulus and E. nitens, respectively. The higher inherent level of total phenols in the branch
sapwood may partly explain why less dysfunction resulted from the inoculation of branches compared to stems. Overall, E. globulus developed
smaller columns of discoloration and decay than E. nitens.</p></div><table style="margin-bottom: 1em" cellpadding="3" class="not_ep_block" border="0"><tr><th valign="top" class="ep_row">Item Type:</th><td valign="top" class="ep_row">Article</td></tr><tr><th valign="top" class="ep_row">Additional Information:</th><td valign="top" class="ep_row">Definitive version is available online at http://www.sciencedirect.com/</td></tr><tr><th valign="top" class="ep_row">Keywords:</th><td valign="top" class="ep_row">Wood decay, Australia, Eucalyptus spp., Wounding</td></tr><tr><th valign="top" class="ep_row">Subjects:</th><td valign="top" class="ep_row"><a href="http://eprints.utas.edu.au/view/subjects/300603.html">300000 Agricultural, Veterinary and Environmental Sciences > 300600 Forestry Sciences > 300603 Pests, Health and Diseases</a></td></tr><tr><th valign="top" class="ep_row">ID Code:</th><td valign="top" class="ep_row">1592</td></tr><tr><th valign="top" class="ep_row">Deposited By:</th><td valign="top" class="ep_row"><span class="ep_name_citation"><span class="person_name">Professor Craig R.
