Performance of planted seedlings in shelterwoods near Prospect, Oregon

Creator:

Giles, Robert Steven

Abstract:

A survey of partial cuts planted with bare-root seedlings, was conducted on the Prospect Ranger District, Rogue River National Forest, Oregon, during the 1977 summer season. The purpose was to assess stocking and its composition under present levels of canopy cover, and to determine relationships between canopy density and performance...

Diurnal and seasonal changes in xylem water potential, stomatal conductance and abscisic acid in five different habitat types of Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco)

Creator:

Murphy, Ellyn Margaret

Abstract:

Sapling Douglas-fir trees on five sites in the Coastal and Cascade Mountain ranges of Oregon were measured five times during the year from the summer of 1977 through the spring of 1978 for diurnal patterns of xylem water potential, stomatal conductance and abscisic acid. Vapor pressure deficit and solar radiation...

Masters Thesis
The effect of plant moisture stress on the physiology and establishment of planted Douglas-fir and ponderosa pine seedlings

Creator:

Cleary, Brian D.

Abstract:

The role of moisture stress in seedling physiology and establishment was studied in both the field environment and laboratory experiments. Plant moisture stress was measured using the pressure chamber technique. This technique was modified and tested using a fascicle of pine needles as a sample, an improvement which allows the...

Dissertation
Relative low temperature tolerance of lodgepole and ponderosa pine seedlings

Creator:

Berntsen, Carl M.

Abstract:

The hypothesis is explored that lodgepole pine at the seedling emergence period is more resistant to low temperatures than ponderosa pine. Differential tolerance between species to low temperatures is then related to the prevalence of lodgepole pine in frost pocket areas in central Oregon to the exclusion of ponderosa pine....

Dissertation
The effect of age on transpiration rates of Douglas-fir seedlings (Pseudotsuga menziesii (Mirb.) Franco)

Creator:

Geppert, Rollin Roger

Abstract:

The objective of this study was to determine the effect of age on rates of transpiration by Douglas-fir seedlings. Seeds were collected from a xeric site (Goldendale, Washington) and a mesic site (Forks, Washington). The seedlings were grown in a cold frame and in a growth chamber for periods of...
