Susceptibility of harvested softwoods to infection by sap-staining fungi
2002 - IRG/WP 02-10435
In the UK a field study programme was carried out to compare the susceptibility of softwood timber from five different commercially important tree species to infection by sap-stain fungi. Logs cut from freshly felled Scots pine (Pinus sylvestris), Lodgepole pine (P. contorta var. latifolia), Sitka spruce (Picea sitchensis), Norway spruce (P. abies) and Japanese larch (Larix leptolepis) were expo...

Factors affecting resistance to sapstain infection in freshly felled softwood logs
2003 - IRG/WP 03-10467
Previous studies in the UK have shown a marked difference in the susceptibility of logs of five softwood species to infection by sapstain fungi over a 4 month field trial. Recently this result has been confirmed and the rank order of greatest to least susceptibility in these commercially important species is lodgepole pine > Scots pine > Norway spruce > Japanese larch > Sitka spruce. C...

Anatomical, physical and chemical changes of Bamboo (Phyllostachys puberscence ) during weathering processes
2008 - IRG/WP 08-10650
Bamboo (Phyllostachys puberscence) culms with 1, 2, 3 year old were exposed to natural weathering condition in Gwangju, Korea for 12 months. Changes in color, surface topography, strength and chemical properties were investigated using various microscopic and instrumental techniques. After one year’s weathering, the color of bamboo became lighter but strengths of bamboo did not change significan...

Characterization of protein patterns from decayed wood of loblolly pine (Pinus taeda L.) by proteomic analysis
2008 - IRG/WP 08-10654
The primary biotic decomposers of wood belong to the basidiomycetes. The members of this group can attack and biodegrade both wood in the forest and in service. By the time wood decay is visible, there has already been a significant loss of strength. The identification of basidiomycetes and other organisms on wood only tell us what is present, not what is actively decaying the wood. When organisms...

Wood Decay Research Using Molecular Procedures, What Can It Tell Us?
2008 - IRG/WP 08-10678
There are many unanswered questions in wood decay and protection research, and no single research technique will ever answer all of these questions. The process of wood decay is a very complex series of biochemical and chemical reactions that are heavily influenced by the hundreds of bacterial and fungal species found on environmental samples of wood. There are a variety of molecular techniques b...

Gene expression of selected decay enzymes produced during biodeterioration of three wood types
2009 - IRG/WP 09-10702
Comparative studies were conducted on the expression of several decay enzyme genes during the decay of pine, cedar, and ACQ treated pine over 10 months. Measurements of MOE, decay rating, and moisture control were monitored for physical properties. Identification of decay fungi and the detection of decay enzymes were carried out before gene expression levels were measured. The MOE of wood stakes d...

DNA-based tools for rapidly detecting, quantifying and monitoring ophiostomatoid fungi on beetles, in trees and wood products
2010 - IRG/WP 10-20450
Approximately half of the trees harvested for commercial purposes are lost because of native or introduced insects or insect-vectored microorganisms. Ophiostomatoid fungi, which are well adapted to dissemination by insects, include ~140 species of saprobes and pathogens. They are present worldwide, have high economical impact and many are subject to quarantine regulation. Thus, it is necessary to ...

Micromorphological and chemical characteristics of waterlogged archaeological bamboos excavated from the Yellow Sea
2012 - IRG/WP 12-10785
Bamboos have widely used as documentation material in Far Eastern countries such China, Korea and Japan. In particular, bamboo slips as documentation material were extensively used even after the wide spread of paper in those countries. A large number of bamboo slips have been excavated from the shipwreck since 2009 in Korea. Understanding the cause of deterioration of ancient bamboos is crucial f...

Young People’s Perceptions about Wood
2017 - IRG/WP 17-40777
The aim of this research is to gain insight into how students from the various undergraduate programs at a university think about wood as the full members of society with a focus on understanding young people’s opinions by asking to write a short essay as a term paper on a wood. This article is a subjective qualitative research by making content analysis based on the evaluation of the term paper...
A Conceptual Review of Young People’s Perceptions about Wood
2018 - IRG/WP 18-40836
This article was adapted from the previous study “Young People’s Perceptions about Wood” prepared by Usta (2017), and extended through the development and evaluation of the initial data in terms of the conceptual framework regarding the descriptions of wood by young people. Because it was highlighted by previous study that the university students as the full members of society have the aware...
