The mycorrhizal associations of western hemlock

Creator:: Kropp, Bradley Ray
Abstract:: Two objectives of this research were to identify fungi which are mycorrhizal with western hemlock and to examine the ecology of hemlock mycorrhizal fungi indigenous to outplanting sites. Another objective was to evaluate the effectiveness of mycorrhizal inoculation in improving the performance of outplanted hemlock seedlings. A list of over...

Genetic considerations in cloning western hemlock

Creator:: Foster, George Samuel
Abstract:: Using clones to regenerate a species new to clonal reforestation presents the forest manager with many problems. A number of interrelated and interdependent research and development activites are needed to answer these technical questions. Network diagraming was used for scheduling research activities and for indicating interdependencies among activities. The resultant...

The physiology of dormancy of western hemlock (Tsuga heterophylla (Raf.) Sarg.) seedlings

Creator:: Nelson, Eric Alan
Abstract:: The physiology of dormancy of western hemlock (Tsuga heterophylla (Raf.) Sarg.) seedlings was examined. Many areas proved to exhibit similarities to those elucidated for Douglas-fir, although significant differences were also found and necessitate the use of caution in extrapolating data from one species to the other.. Dormancy of western hemlock...

Provenance variation in Western hemlock (Tsuga heterophylla (Raf.) Sarg.) seedlings

Creator:: Kuser, John E.
Abstract:: A range-wide sample of 221 provenances of western hemlock (Tsuga heterophylla (Raf.) Sarg.) showed much variation in several characteristics. Variation in seed weight was significant, but not correlated with seed source latitude, elevation, or distance from the ocean. Variation in the frequency of 4-cotyledon seedlings was significant at regional, provenance,...

The impact of wood variability on the drying rate at different moisture content levels

Creator:: Berberović, Adin
Abstract:: Variability in wood properties causes boards within a stack of lumber to dry at different rates and reach different moisture content levels after drying is completed. The consequence is that the boards will have properties that differ from ones that were intended to be achieved by the drying process. The...

Logs as sites of tree regeneration in Picea sitchensis-Tsuga heterophylla forests of coastal Washington and Oregon

Creator:: Harmon, Mark E.
Abstract:: Logs are seedbeds for trees in many Picea sitchensis-Tsuga heterophylla forests of Washington and Oregon. Factors affecting this close association, including seed retention and seedling establishment on logs and successional changes in log characteristics, are explored In this study. Field and laboratory experiments indicated that competition with vegetation on the...

Carbohydrates in a thermomechanical pulp, a sulfite pulp, and a solvent sulfite pulp from western hemlock

Creator:: Ni, Hae-Rong
Abstract:: A thermomechanical pulp, a high yield sulfite pulp, and a high yield solvent sulfite pulp from western hemlock [Tsuga heterophylla (Raf.) Sarg.] wood were investigated to determine the amount of carbohydrate material present and to elucidate the structures of the carbohydrates. The effects of the three pulping processes, which were...

The influence of pre-harvest killing of western hemlock on subsequent stump invasion by Fomes annosus

Creator:: Laird, Peter Paul
Abstract:: This study concerns the effect of pre-harvest killing of commercial sized, forty year old western hemlock (Tsuga heterophylla (Raf.) Sarg.) on subsequent stump infection by Fomes annosus (Fr.) Karst. Further evaluations were made on tree drying, loosening of bark, wood deterioration and rate of crown and cambial death. Findings on...

Structural development of late successional forests in the central Oregon Coast Range : abundance, dispersal, and growth of western hemlock (Tsuga heterophylla) regeneration

Creator:: Schrader, Barbara A.
Abstract:: Patterns of western hemlock regeneration were studied in relation to forest structural development and environment in the Oregon Coast Range. Density of western hemlock seedlings was examined across the climatic gradient from cool, moist coastal areas to the seasonally hot and dry Willamette Valley Margin. Seedling densities were most strongly...
