Ability of natural extracts to limit mold growth on Douglas-fir sapwood

Creator:: Maoz, Michal, Karchesy, Joseph J., and Morrell, Jeffrey J.
Abstract:: The ability of selected plant extracts from wood and foliage to inhibit mold regrowth on fungal colonized wood was evaluated on Douglas-fir sapwood. Most foliage extracts produced some inhibition of Graphium or Trichoderma species, but isolations of other fungi increased following treatment. Five out of eight wood extracts produced 50%...

Antifungal effects of hinokitiol and its sodium salt for wood protection

Creator:: Li, Shujun, Freitag, Camille M., Morrell, Jeffrey J., and Okabe, Toshihiro
Abstract:: The ability of natural and synthetic hinokitiol, as well as a water soluble derivative (hinokitiol sodium salt), to protect wood against fungal attack was examined. Synthetic and natural hinokitiol provided similar protection. All three materials exhibited similar antifungal activity against Aspergillus niger and Penicillium citrinum on yellow poplar wafers at...

Examination of moisture content variation within an operational wet deck

Creator:: Schimleck, Laurence, Love-Myers, Kim, Sanders, Joe, Raybon, Heath, Daniels, Richard, Andrews, Edward, and Schilling, Erik
Abstract:: Many forest products companies in the southeastern United States store large volumes of round-wood under wet storage. Log quality depends on maintaining a high and constant wood moisture content; however, limited knowledge exists regarding moisture variation within individual logs, and within wet decks as a whole, making it impossible to...

An integrated approach using Bacillus subtilis B26 and essential oils to limit fungal discoloration of wood

Creator:: Wang, Yu, Chang, Jianmin, Morrell, Jeffrey J., Freitag, Camille M., and Karchesy, Joseph J.
Abstract:: Bacillus subtilis and essential oils have been explored separately for their ability to limit colonization by wood stain and mold fungi, but neither approach has been completely effective. One alternative strategy would be to combine the bacterial biocontrol with one or more natural products extracts. In this report, the ability...

Equations for predicting height to crown base for fourteen tree species in southwest Oregon

Creator:: Ritchie, Martin W., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations are presented for predicting height to crown base (or bole ratio) for fourteen species of trees common to the mixed-conifer zone of southwest Oregon. Nonlinear regression was used to fit a weighted logistic function for each species. The independent variables include height, crown competition factor in larger trees, stand...

Equations for predicting the 5-year height growth of six conifer species in southwest Oregon

Creator:: Ritchie, Martin W., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: Equations for predicting individual-tree height growth per 5-year period are presented for Douglas-fir, white fir, grand fir, ponderosa pine, sugar pine, and incense-cedar growing in the mixed-conifer zone of southwest Oregon. The data used to develop the equations came from 3,648 trees sampled from 391 stands in the study area....

Equations for predicting the height to crown base of six tree species in the central western Willamette Valley of Oregon

Creator:: Zumrawi, Abdel Azim M. A., Hann, David W., and Oregon State University. Forest Research Laboratory
Abstract:: This paper presents equations developed to predict the height to live crown base of six species in the central western Willamette Valley of Oregon. Weighted nonlinear regression was used to fit a separate logistic equation for each species. The predictor variables are total tree height, crown competition factor in trees...

Sustainable bio-composites for highway infrastructure: Feasibility of material substitution in existing products

Creator:: Karas, Michael and Muszynski, Lech
Abstract:: The U.S, Forest Service regularly removes tons of dead biomass from federal forestlands to control and prevent devastating wildfires. Every year thinning young trees and brush, as well as removing dead biomass from the forest floor generates large quantities of low-grade woody material for which there is little use. Currently...

Bibliography of Douglas-fir provenance studies, 1907-1974

Creator:: Hermann, Richard K., Ching, Kim K., and Oregon State University. Forest Research Laboratory
Abstract:: Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is one of the world's most important and valuable timber trees. Its natural distribution in North America resembles an inverted V with uneven sides. From the apex in British Columbia, the western half extends along the Pacific mountain ranges into California for about 2,200 km...
