Conserving energy by environmentally acceptable practices in maintaining and procuring transmission poles for long service ; August 1988

Creator:: Morrell, Jeffrey J. and Corden, M. E. (Malcolm E.)
Abstract:: The eighth annual report details continued progress on each of the five objectives. In this year's report, Objectives II and III from previous reports have been combined to reflect the similarity of each effort. Improved fumigants: The previously established field trials continue to demonstrate the superior performance of both chioropicrin...

Potential for using through-boring to improve groundline treatment of Australian wood species: A preliminary study

Creator:: Morrell, Jeffrey J. and Norton, Jack
Abstract:: An aging electricity distribution system and reduced availability of naturally durable tropical hardwoods in Australia will combine in the next decade to produce a major shortage of poles. One approach to mitigating this shortage is to utilize lower durability species and improve the penetration of preservatives into the refractory heartwood...

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...

Effects of incising on lumber strength and stiffness: Relationships between incision density and depth, species, and MSR grade

Creator:: Winandy, Jerrold E. and Morrell, Jeffrey J.
Abstract:: This report describes the relationship of incising-induced strength loss in bending as a function of preservative treatment and incising pattern, density, and depth of penetration for various machine stress-rated (MSR) grades of full-size 2 by 4 Douglas-fir, Hem-Fir, and Spruce-Pine-Fir (South) dimension lumber. This study may represent a worst-case "incising...

Evaluating potential decay control agents with a small block test

Creator:: Corden, Malcolm E. and Morrell, Jeffrey J.
Abstract:: A small-scale test was developed to evaluate the ability of fungicides to control decay fungi established in wood. The test, which uses blocks 2.5 x 2.5 x 10 cm, tests the ability of a chemical to migrate from the middle of the block to control a previously established decay fungus,...

Relationship between incipient decay, strength, and chemical composition of Douglas-fir heartwood

Creator:: Winandy, Jerrold E. and Morrell, Jeffrey J.
Abstract:: A new laboratory technique to simulate the initiation of wood decay and to assess the effects of incipient decay on material properties is described. Douglas-fir heartwood specimens were exposed to brown-rot (Postia placenta and Gloeophyllum trabeum) fungi for various periods. Bendlng properties were determined by nondestructive and destructive tests, and...

Effects of bison on willow and cottonwood in northern Yellowstone National Park

Creator:: Painter, Luke E. and Ripple, William J.
Abstract:: On the northern ungulate winter range of Yellowstone Park, willow (Salix spp.) and cottonwood (Populus angustifolia and P. balsamifera) have increased in height and cover in some places since the reintroduction of wolves (Canis lupus) and the subsequent changes in elk (Cervus elaphus) behavior and population densities. However, in the...

Date of earlywood-latewood transition in provenances and families of loblolly pine, and its relationship to growth phenology and juvenile wood specific gravity

Creator:: Jayawickrama, K. J. S., McKeand, S. E., Jett, J. B., and Wheeler, E. A.
Abstract:: When grown together in plantations, fast-growing southern and coastal sources of loblolly pine (Pinus taeda L.)often have lower wood specific gravity than northern and inland sources. This study investigated whether this phenomenon could be explained by a later transition to latewood, associated with a longer period of height growth, of...

Rootstock effects on scion growth and reproduction in 8-year-old grafted loblolly pine

Creator:: Jayawickrama, K. J. S., McKeand, S. E., and Jett, J. B.
Abstract:: Contributions of sites, rootstocks, and scion clones (and the nteractions between these factors) to scion growth and reproduction were studied in loblolly pine (Pinus taeda L.). Twenty-five full-sib families were used as rootstocks. Six scion clones were grafted on them in all combinations. Study sites were three seed orchards in...

Ionic balance and organic acids in western redcedar, western hemlock, and Douglas-fir seedlings grown in low- and high-N soils

Creator:: Graff, J. E., Hermann, Richard K., and Zaerr, J. B.
Abstract:: Seedlings of western redcedar (Thuja plicata Donn ex. D. Don), western hemlock (Tsuga heterophylla (Raf.) Sarg.), and Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) were transplanted into soils with low and high levels of available NO3 – (and total N). Current-year foliage was sampled after 10 weeks to determine the effect of...
