Fiber length in young hybrid Populus stems grown at extremely different rates

Creator:: DeBell, Jeffrey D., Gartner, Barbara L., and DeBell, Dean S.
Abstract:: Length of libriform fibers was measured in rings 2 7 at breast height in 7-year-old hybrid poplar stems from two clones (11-11, a Populus trichocarpa Torr. & Gray ´ P. deltoides Bartr. ex Marsh. hybrid; and D-01, of unknown taxonomic identity) grown in a controlled test of three spacings (0.5,...

Wood quality studies in second-growth western redcedar (Thuja plicata Donn.)

Creator:: DeBell, Jeffrey D.
Abstract:: Western redcedar (Thuja plicata Donn.) is a valuable commercial species found in the northwestern United States and southwestern Canada. This dissertation includes four papers focused on wood and stem characteristics of second-growth western redcedar, and how those characteristics vary within the stem or how they are influenced by cultural practices....

Wood density of young-growth western hemlock: relation to ring age, radial growth, stand density, and site quality

Creator:: DeBell, Dean S., Singleton, Ryan, Gartner, Barbara L., and Marshall, David D.
Abstract:: Breast-high stem sections were sampled from 56 western hemlock (Tsuga heterophylla (Raf.) Sarg.) trees growing in 15 plots representing a wide range of tree and site conditions in northwestern Oregon. Growth and wood density traits of individual rings were measured via X-ray densitometry, and relationships of ring density and its...

Wood density of Eucalyptus saligna grown in Hawaiian plantations: effects of silvicultural practices and relation to growth rate

Creator:: DeBell, Dean S., Keyes, Christopher R., and Gartner, Barbara L.
Abstract:: We evaluated effects of chemical fertilizer, spacing, and interplanted nitrogen-fixing trees on wood density and diameter growth of 15-year-old Eucalyptus saligna trees. The trees were grown in silvicultural trials established on former sugarcane land on the island of Hawaii. Elevation was 480 m, slopes were gentle, and annual rainfall averaged...

Effect of extraction on wood density of western hemlock (Tsuga heterophylla (Raf.) Sarg.)

Creator:: Singleton, Ryan, DeBell, Dean S., and Gartner, Barbara L.
Abstract:: Extractives can account for between 1 to 20% of the oven-dry weight of wood of various tree species and can influence wood density values appreciably. Removing these chemical deposits (extraction)in wood samples can help establish a consistent baseline for comparing wood densities where extractives are expected to differ between sample...

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...

OPEnS Hub: Real-time Data Logging, Connecting Field Sensors to Google Sheets

Creator:: DeBell, Thomas C., Goertzen, Luke, Larson, Lars, Selbie, William, Selker, John S., and Udell, Chet
Abstract:: In Earth science, we must often collect data from sensors installed in remote locations. Retrieving these data and storing them can be challenging. Present options include proprietary commercial dataloggers, communication devices, and protocols with rigid software and data structures that may require ongoing expenses. While there are open-source solutions that...

Time and distance to clear wood in pruned red alder saplings

Creator:: DeBell, Dean S., Harrington, Constance A., Gartner, Barbara L., and Singleton, Ryan
Abstract:: This paper was published in: Deal, R.L. and C.A. Harrington, eds. 2006. Red alder—a state of knowledge. General Technical Report PNW-GTR-669. Portland, OR: U.S. Department of Agriculture, Pacific Northwest Research Station. 150 p.

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...
