Influence of red alder competition on cambial phenology and latewood formation in Douglas-fir

Creator:: Grotta, A. T., Gartner, Barbara L., Radosevich, S. R., and Huso, M.
Abstract:: To better understand the influence of competition on wood formation and wood quality in Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco), patterns of cambial growth and latewood production were examined for one growing season in 15-year-old plantations with similar densities but differing Douglas-fir/red alder (Alnus rubra Bong.) ratios. The treatments consisted of...

Effects of pruning on wood density and tracheid length in young Douglas-fir

Creator:: Gartner, Barbara L., Robbins, J. M., and Newton, M.
Abstract:: To study whether pruning young Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco var. menziesii) hastens the transition from juvenile to mature wood, we investigated the effects on wood properties in an intensively managed young plantation in the Coast Range of Oregon. Ten years after trees were pruned to a fixed height (3.4...

Fungal staining of ponderosa pine sapwood: Effects of wood preconditioning and bioprotectants

Creator:: Morrell, Jeffrey J. and Sexton, Camille M.
Abstract:: Differences in stain susceptibility were evaluated on sterile and unsterile samples of freshly sawn, frozen and thawed, or oven-dried and rewetted ponderosa pine sapwood. Samples treated with sterile medium or with medium inoculated with either Pseudomonas putida or Bacillus subtilis were inoculated with selected wood-staining fungi. In general, fresh unsterile...

Fungi colonizing redwood in cooling towers: Identities and effects on wood properties

Creator:: Morrell, Jeffrey J. and Smith, Susan M.
Abstract:: Heartwood from coastal redwood [Sequoia sempervirens (D. Don.) Endl.] is very durable and is often used untreated in harsh environments, such as cooling towers of power or chemical processing plants. Wood in this environment is often attacked by soft rot fungi. Some wood users attempt to bolster protection by including...

Laboratory decay resistance of preservative-treated red alder

Creator:: Mitchoff, M. E. and Morrell, Jeffrey J.
Abstract:: Alder represents an abundant but underutilized resource that has little natural resistance to decay. Treated alder might be used for stakes, posts, or other nonstructural applications. The performance of alder treated with chromated copper arsenate (CCA), copper 8 quinolinolate, zinc naphthenate (ZN), or thiocyanomethylthiobenzothiazole (TCMTB) was assessed in soil block...

Durability of a changing western redcedar resource

Creator:: Freitag, Camille M. and Morrell, Jeffrey J.
Abstract:: The heartwood of western redcedar (Thuja plicuta) is known for its natural resistance to fungal attack, but some users of western redcedar utility poles have suggested that its durability may be diminished as suppliers begin to harvest trees from younger stands. The decay resistance of western redcedar samples from the...

Assessing Fungal Decay of Wood by Small-scale Toughness Tests

Creator:: Sexton, Camille M., Corden, Malcolm E., and Morrell, Jeffrey J.
Abstract:: Impact bending and breaking radius were used to measure loss in toughness caused by basidiomycetes isolated from wood. Small test pieces were used to accelerate testing. Wide differences were found among, and sometimes within, the 26 species tested. Brown-rot fungi tended to cause greater losses than white-rot fungi, but no...

The effect of pH on decomposition of Mylone (dazomet) and tridipam to fungitoxic methylisothiocyanate in wood

Creator:: Morrell, Jeffrey J., Sexton, Camille M., and Lebow, Stan
Abstract:: Mylone@ and tridipam are two solid chemicals that decompose to produce methylisothiocyanate (MIT), a highly effective wood fumigant. In this study, two techniques -- a rapid, test-tube method and small-scale, wood-block assay -- were used to determine the effect of the pH of various chemical buffers on the decomposition of...

Decay resistance of saltwater-exposed Douglas-fir piles

Creator:: Schneider, Philip F., Freitag, Camille M., and Morrell, Jeffrey J.
Abstract:: Wood that is submerged in fresh water for long periods has increased permeability and other changed properties. Wood that is submerged in salt water may absorb considerable quantities of salts, which may render the wood resistant to microbial colonization. In this report, we describe decay tests on Douglas-fir sapwood and...

Controlling decay fungi in Douglas-fir heartwood with pelletized sodium n-methyldithiocarbamate

Creator:: Sexton, Camille M., Morrell, Jeffrey J., and Newbill, Mark A.
Abstract:: A small block test was used in assessing whether pelletized sodium n-methyldithiocarbamate (NaMDC) would decompose and produce methylisothiocyanate (MITC) and thereby eliminate Antrodia carbonica colonies from Douglas-fir heartwood. Also evaluated were the effects of wood moisture content, dosage, incubation period, pH level, and presence of copper sulfate on percentage of...
