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

Singleton, R.; DeBell, D. S.; Gartner, B. L. (Society of Wood Science and Technology, 2003-07)

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

Gartner, B. L.; Robbins, J. M.; Newton, M. (Society of Wood Science and Technology, 2005-04)

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 manag ...
Effects of release from suppression on wood functional characteristics in young Douglas-fir and western hemlock

Renninger, H. J.; Gartner, B. L.; Meinzer, F. C. (NRC Canada, 2006)

Little is known of wood properties in trees that were initially suppressed and subsequently released from suppression. The purpose of this study was to assess differences in growth ring width, specific conductivity (Ks), ...
Impact of the foliar pathogen Swiss needle cast on wood quality of Douglas-fir

Johnson, G. R.; Grotta, A. T.; Gartner, B. L.; Downes, G. (NRC Canada, 2005)

Many stands of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) near coastal areas of Oregon and Washington are heavily infected with the foliar pathogen causing Swiss needle cast (SNC) disease, and yet there is very l ...
Sapwood and inner bark quantities in relation to leaf area and wood density in Douglas-fir

Gartner, B. L. (International Association of Wood Anatomists, 2002)

The relationships between leaf area and sapwood and inner bark quantities (widths, areas, and volumes) were studied in an attempt to understand the design criteria for sapwood quantity in eighteen 34-year-old Douglas-fir ...
Wood density and fiber length in young populus stems: relation to clone, age, growth rate, and pruning

DeBell, D. S.; Singleton, R.; Harrington, C. A.; Gartner, B. L. (Society of Wood Science and Technology, 2002)

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 avera ...
Wood density and hydraulic properties of ponderosa pine from the Willamette Valley vs. the Cascade Mountains

Bouffier, L. A.; Gartner, B. L.; Domec, J.-C. (Society of Wood Science and Technology, 2003)

The Willamette Valley (WV) race of ponderosa pine (Pinus ponderosa) is being widely planted for timber in the Willamette Valley, western Oregon, because it grows in habitats that are either too wet or too dry for Douglas ...
