Wood density and fiber length in young populus stems: relation to clone, age, growth rate, and pruning

Creator:: DeBell, Dean S., Singleton, Ryan, Harrington, Constance A., and Gartner, Barbara L.
Abstract:: Cross-sectional disks were cut at two stem heights (1.5 m and 3.0 m) from 9-year-old trees of three Populus clones grown in an intensively-cultured plantation in western Washington. At age 1.5 years, when the trees averaged 3.4 m tall, half of the trees were pruned by removing all branches below...

Environmental effects on heartwood extractive content and their consequences for natural durability in Douglas-fir and western redcedar

Creator:: Taylor, Adam McVaugh, 1969-
Abstract:: Heartwood can have properties that are distinct from sapwood, including resistance to insect and microbial attack. Despite the practical importance of heartwood formation in trees, a review of the literature revealed that little was known about the effects of environmental factors on heartwood quality or how variations in heartwood properties...

Effects of live crown on vertical patterns of wood density and growth in Douglas-fir

Creator:: Gartner, Barbara L., North, Eric M., Johnson, G. R., and Singleton, Ryan
Abstract:: It would be valuable economically to know what are the biological triggers for formation of mature wood (currently of high value) and (or) what maintains production of juvenile wood (currently of low value), to develop silvicultural regimes that control the relative production of the two types of wood. Foresters commonly...

Effects of selected management practices on lumber grade and drying properties of two central hardwood species

Grain and grade sorting to improve drying quality in western red cedar

Creator:: Millar, Sita, Gudmundson, Mervil, Western Dry Kiln Association, and Western Dry Kiln Association. Meeting (51st : 2000 : Reno, Nev.)
Resource Type:: Conference Proceeding
Full Text:: either through pruning or in new plantations. This is especially prevalent in British Columbia where most

Characterization of Grape Cane Fibers as a Composite Reinforcement

Creator:: A. Bakar, Balkis F.
Abstract:: Using plant fibers as a potential renewable material to substitute for glass fibers in fiber-reinforced polymer composites has been growing since the late 1990s. Due to high demand, there has been a shift towards ‘green concept’ material in many applications. Numerous secondary plant fibers have been explored as a source...

Management Strategies for Small, Structurally Diverse & Income-Generating Forests

Creator:: Geisel, Julian
Abstract:: Parcellization of the rural landscape threatens the provision of social, ecological and economic benefits to society due to loss of economies of scale. A continued provision requires new approaches to forest management for multiple, interconnected goals. I used interviews, archival records and field measurements to learn how select, experienced owners...

Effects of release from suppression on hydraulic architecture, photosynthetic capacity and functional wood characteristics in Douglas-fir and western hemlock

Creator:: Renninger, Heidi
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), a shade intolerant species, and western hemlock (Tsuga heterophylla (Raf.) Sarg.), a shade tolerant species, were compared to learn more about the temporal pattern of release from suppression in both species, whether hydraulic architecture or photosynthetic capacity constrain release and how wood functional properties change...

Relationships of density, microfibril angle, and sound velocity with stiffness and strength in mature wood of Douglas-fir

Creator:: Lachenbruch, Barbara, Johnson, G. R., Downes, G., and Evans, R.
Abstract:: The relative importance of density, acoustic velocity, and microfibril angle (MFA) for the prediction of the stiffness (MOE) and strength (MOR) has not been well established for Douglas-fir (Pseudotsuga menziesii). MOE and MOR of small clear specimens of mature wood were better predicted by density and velocity than by either...
