Survival of planted ponderosa pine in Southern Oregon

Creator:: Hermann, Richard K. and Oregon State University. Forest Research Laboratory
Abstract:: Planting techniques, size and age of seedlings, and protection against animals were investigated for their influence on survival of ponderosa pine at two sites in southern Oregon. Caging and mulching with paper were the most effective measures for reducing mortality. Preliminary trials prior to large-scale planting were recommended for determining...

The expression of functional traits during seedling establishment in two populations of Pinus ponderosa from contrasting climates

Creator:: Kerr, Kelly L.
Abstract:: Vegetation patterns and species distributions are strongly linked to soil moisture regimes, and populations within a species from contrasting climatic regimes could exhibit differences in the degree to which certain functional traits related to establishment are expressed. Tree seedling survival is crucial for forest regeneration, and thus may be a...

Recruitment of ponderosa pine seedlings beneath partial overstories

Creator:: Keyes, Christopher R.
Abstract:: The objective of this project was to investigate the fate of ponderosa pine regeneration from seed to established seedling, and to determine the relative influences of several important stand elements on those fates. The project was carried out in a series of observational and experimental recruitment studies in central Oregon....

Effects of fall lifting and long-term freezer storage on ponderosa pine seedling physiology and quality

Creator:: Omi, Steven Katsu
Abstract:: Two-year-old ponderosa pine (Pinus ponderosa Dougl. ex Laws.) seedlings from two Oregon seed sources were lifted three times in the fall, stored below freezing (-1.5°C), and compared to seedlings that were handled conventionally (spring lifting followed by short-term cold storage, 2-4°C). Based on patterns of budbreak in a greenhouse and...

Fertilization of 2-0 ponderosa pine seedlings in the nursery and field : morphology, physiology, and field performance

Creator:: Gleason, John F.
Abstract:: Two-year-old ponderosa pine (Pinus ponderosa Laws.) from two seed sources were grown at two nurseries. The Fremont seed source was raised at Bend and Stone Nursery; the Ochoco was grown at only the Bend Nursery. The seedlings were fertilized in late September-early October with nitrogen (N) or nitrogen plus potassium...

Performance of Pinus ponderosa seedlings in clearcuts, patch cuts and undisturbed forests on lavas

Creator:: Hutten, Martin A. B.
Abstract:: The survival, growth, foliar nutrient status, ectomycorrhiza (EM) colonization, and associative N-fixation of ponderosa pine seedlings (Pinus ponderosa var. ponderosa Doug!. ex Laws.) were studied under different gap sizes in forest canopy during the first growing season. Seedling performance variables were assessed relative to gap size of the forest canopy...

The influence of antidesiccants on field performance and physiology of 2+0 ponderosa pine (Pinus ponderosa Dougl.) seedlings

Creator:: Vera-Castillo, J. A. Gil
Abstract:: This thesis research examines the effects of film-forming antidesiccants applied to dormant pondexosa pine (Pinus ponderosa Dougl.) seedlings after being lifted and to actively growing seedlings. The basic proposition was that antidesiccants would have a positive effect on reducing water loss in ponderosa pine seedlings. In order to evaluate the...

Geographic variation in central Oregon ponderosa pine (Pinus ponderosa Laws.) : seed germination; seed, wing, and cone morphology; seed color

Creator:: Weber, John C., 1948-
Abstract:: Geographic variation was investigated among 225 locations from five geographically disjunct regions in central Oregon. Characters included: germination speed and uniformity in two test environments differing in stratification period and incubation temperature; weight, three dimensions and three 'angles' of seeds; weight and three dimensions of wings; cone length and scale...

Seedling response to vegetation management in northeastern Oregon

Creator:: Lindsay, Amanda A.
Abstract:: Northeastern Oregon geology and climate provides moderately productive conditions for forest management and timber production. Although site preparation and planting are commonly used silvicultural practices, little research exists on the efficacy of specific forest herbicides and responses of seedling survival and growth in this region. This research seeks to improve...
