- <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.
