Tropolone content of increment cores as an indicator of decay resistance in western redcedar

Creator:: DeBell, Jeffrey D., Morrell, Jeffrey J., and Gartner, Barbara L.
Abstract:: The high decay resistance of western redcedar (Thuja plicata Donn) is due to the presence of toxic extractives, called tropolones, in the heartwood. Therefore, tropolone content may be used as an indicator of decay resistance. With increment core-sized samples of western redcedar heartwood, we used gas chromatography to measure tropolone...

Thermoperiods and soil temperatures as they affect growth and dormancy of Douglas-fir seedlings of different geographic origin

Creator:: Lavender, Denis P., Overton, W. Scott, and Oregon State University. Forest Research Laboratory
Abstract:: The effects of a range of thermoperiods and soil temperatures upon growth of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) seedlings were studied. The seeds, of varieties glauca and menziesii, came from eight widely separated areas. Plants from both varieties made maximum growth with soil and air temperatures between 18 and 24...

The influence of wood moisture content on the fungitoxicity of methylisothiocyanate in Douglas-fir heartwood

Creator:: Zahora, Andrew R. and Morrell, Jeffrey J.
Abstract:: High concentrations of the fumigant methylisothiocyanate (MITC) will effectively control decay fungi in large wood structures, but the fungitoxicity of low MITC concentrations and the influence of wood moisture content (MC) on its performance are not well understood. The MC of Douglas-fir heartwood greatly influenced the susceptibility of the decay...

The hydrology of the humid tropics

Creator:: Wohl, Ellen, Barros, Ana, Brunsell, Nathaniel, Chappell, Nick A., Coe, Michael, Giambelluca, Thomas, Goldsmith, Steven, Harmon, Russell, Hendrickx, Jan M. H., Juvik, James, McDonnell, Jeffrey, and Ogden, Fred
Abstract:: Hydrological processes in the humid tropics differ from other regions in having greater energy inputs and faster rates of change, including human-induced change. Human influences on population growth, land use and climate change will profoundly influence tropical hydrology, yet understanding of key hydrological interactions is limited. We propose that efforts...

The genus Pseudotsuga : ancestral history and past distribution

The effects of chromated copper arsenate and ammoniacal copper zinc arsenate on shear strength development of phenolic resin to Sitka spruce bonds

Creator:: Prasad, T. R. Narayana, Humphrey, Philip E., and Morrell, Jeffrey J.
Abstract:: Preservative treatment of whole, wood-based composite products (mainly panels) has disadvantages; problems largely stem from swelling, strength loss, and incomplete or inappropriate penetration during treatment, and distortion during redrying. Pretreatment of comminuted wood prior to mat lay-up is one alternative, though the addition of chemicals may affect bonding during subsequent...

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...
