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...

Growth and moisture relations of western hemlock seedlings as affected by root or shoot disturbance

Creator:: Morris, John W. (John William), 1954-
Abstract:: The need for increased efficiency in regeneration of western hemlock (Tsuga heterophylla (Raf.) Sarg.) requires greater understanding of seedling physiology. Experiments examined western hemlock seedling growth responses to in-bed root pruning, and pruning of shoots or roots prior to transplanting. Measurement of plant moisture stress (PMS) after physical root disturbance,...

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,...

Patterns of growth and seasonal changes in the concentrations of abscisic acid and indoleacetic acid in roots of western hemlock

Creator:: Brown, Charles Joseph
Abstract:: The capacity for root growth and concentration of indole-3-acetic acid and abscisic acid in the roots of western hemlock seedlings was investigated. The root regenerating capacity (RRC) was defined as the increase in root length, greater than 5 mm, following a 28-day test period. RRC measurements over a two-year period...

Transformation of Western Hemlock Tree Crowns by Dwarf Mistletoe

Creator:: Calkins, Stephen J.
Abstract:: Hemlock dwarf mistletoe (Arceuthobium tsugense subsp. tsugense) is an arboreal, hemiparasitic plant that principally parasitizes western hemlock (Tsuga heterophylla). Hemlock dwarf mistletoe exerts a profound influence on infected trees that can drastically change the structure of the tree crown due to reduced growth, top dieback, branch deformation and death, resulting...

Effect of high temperature drying on bending and shear strengths of western hemlock

Creator:: Thiam, Massamba
Abstract:: The advantages of high-temperature drying are faster drying, reduced inventory, reduced energy requirements, and reduced equilibrium moisture content. However the disadvantages are higher initial costs of the kiln, greater power needs, knot dropout, and reduction in some strength properties. The latter was the subject of this study. Three hundred pieces...
