Douglas fir (Pseudotsuga menziesii var. glauca (Mayr) Franco), and western larch (Larix occidentalis Nutt.) are species of ecological and commercial importance that occur throughout the Western United States. Effective reforestation of these species relies on successful seedling establishment, which is affected by planting stock quality, stocktype size, and site preparation techniques. This. The Plants Database includes the following 2 subspecies of Pseudotsuga menziesii. Click below on a thumbnail map or name for subspecies profiles.

Tubercles of Pseudotsuga menziesii consisted of clusters of ectomycorrhizae surrounded by a peridiumlike rind. Energy dispersive spectroscopy demonstrated that crystals found in the zone of loose hyphae extending from the inner rind to the mantle of each root probably contain calcium oxalate. Inner mantle and Hartig net hyphae showed a labyrinthine branching pattern and stored carbohydrates. Juvenile-Mature Correlations in Selected Douglas-fir [Pseudotsuga menziesii (Mirb.)

Insight into influences on successful seedling establishment could be essential to future regeneration of British Columbia’s interior Douglas-fir (Pseudotsuga menziesii var. glauca) forests, particularly as climate changes. Areas of harsh climatic conditions have low regenerative capacity and require management decisions leading to enhanced seedling establishment. Variable retention.

Douglas-fir [Pseudotsuga menziesii (Mirb) Franco] is a conifer native to the Pacific North-West of the United States and Canada, and one of the most important timber species Europe, it is frequently used for reforestation, partly to meet increasing demand for its wood, which has outstanding mechanical properties and by: 3.
In this study, we investigate the potential of fine spectral resolution imagery to measure the effects of repeated fertilization treatments on pigment and nutrient contents of a Douglas-fir (Pseudotsuga menziesii var menziesii (Mirb.)

REHFELDT' USDA Forest Service, Intermountain Research Station, Ogden, Utah (U.S.A.) (Accepted 2 August ) ABSTRACT Rehfeldt, G.E., Carr.) and 1 + 1 Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) were grown in a nursery at the Bush Estate, Scotland.
Batches were lifted and cold stored at °C in November, December and. Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) is one of the best conifer timber species. Its bark contains a substantial proportion of cork that may have a valorization potential, given.
Here, we studied the biological activity of a commercially available Douglas fir (Pseudotsuga menziesii) essential oil (DEO) in a human dermal fibroblast model of chronic inflammation and fibrosis induced by stimulation with cytokines.
Chemical analysis of DEO indicated that its major chemical components (i.e. >5%) were beta-pinene (23%. The volatile leaf oils of the coastal and Rocky Mountain varieties of the Douglas fir were found to have distinctive terpene compositions.
The relative amounts of l-β-pinene, sabinene, 3-carene, α- and γ-terpinene, terpinolene, l-terpinenol, citronellol, citronellyl and geranyl acetate (relatively large in the former variety); and santene, tricyclene, l-camphene, limonene, and l-bornyl.

Two newly discovered ectotrophic mycorrhizae of Douglas fir (Pseudotsuga menziesii (Mirb.)Franco), each formed by a distinct strain of Poria terrestris (DC.

Douglas fir (Pseudotsuga menziesii (Mirb.)) is a coniferous species native of the West Coast of North America and is one of the most important worldwide timber Europe, it is frequently used to satisfy an increasing demand for its wood, which presents outstanding mechanical properties and.
Douglas‐fir (Pseudotsuga menziesii) is one of numerous wide‐range forest tree species represented by subspecies/varieties, which hybridize in contact study examined the genetic structure of this North American conifer and its two hybridizing varieties, coastal and Rocky Mountain, at intervarietal and intravarietal level.
Growth, phenology and frost tolerance of seedlings from 50 populations of Douglas-fir (Pseudotsuga menziesii var. glauca) were compared in 12 environments. Statistical analyses of six variables.
Douglas fir (Pseudotsuga menziesii (Mirb.) Franco) was first introduced to Europe from North America more than years ago, was then planted on a large scale and is now the economically most important exotic tree species in European forests.
This literature review summarizes the current knowledge on the effects of Douglas fir on soil chemistry, plants, arthropods and fungi. Experiments were conducted on 1‐year‐old Douglas fir [Pseudotsuga menziesii (Mirb.)Franco] and 2‐ to 3‐month‐old alder [Alnus rubra (Bong)] seedlings growing in drying soils to determine the relative influence of root and leaf water status on stomatal conductance (g c).The water status of shoots was manipulated independently of that of the roots using a pressure chamber that enclosed.
Growth, physiological and biochemical measurements. To evaluate the growth status of ica seedlings under drought conditions, growth-related parameters were determined in 24 seedlings from each treatment at the initial stage of water stress and at the final harvesting time, including the leaf number, length and width.
After drought stress, the contents of auxin, abscisic acid and. Terpene changes due to maturation and canopy level in Douglas-fir (Pseudotsuga menziesii) flush needle oil. Biochemical Systematics and Ecology23 (5), DOI: /(95)Q.
Here, we focused on molecular-level impacts of DECe to Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), which is one of the most ecologically and economically important tree species in the world.
15 – 16 We tested the hypothesis that 2 weeks of controlled exposure to DECe will induce certain distinct transcriptome changes in Douglas-fir.Does prolonged stratification of Douglas fir influence the yield of seedlings?
