The response of ponderosa pine to a stress signal from interior Douglas-fir may have a large cost and little benefit if the damaging agent is host-specific, but be worth investing in constitutive Cited by: Douglas-fir (Pseudotsuga menziesii [Mirb.] Franco) planted in the Pacific Northwest (Petersen and Newton , Cole and Newton , Newton and Preest , Wagner et al. ). However, the cost-benefit relationship is not clear because spatial requirements for maximum seedling growth are not well understood. Trees systematically planted where.
In plantation forests, competition from unwanted vegetation may reduce survival and negatively impact tree growth. The goal of this study was to examine the influence of vegetation management treatments on plant water relations and wood properties. Control trees (no treatment) were compared to trees subjected to post-planting competing vegetation control for five consecutive years after : Joyce Aernouts, Carlos A. Gonzalez-Benecke, Laurence R. Schimleck. A pin meter can be used to measure the moisture in Douglas fir. Q: What types of moisture meters are there? A: Pin and pinless models are two of the most common types of wood moisture meters. The latest models have an LCD screen. Wood moisture meters should also have settings specific to ‘wood species’.
The results of these experiments suggest that long nights are more effective than moisture stress treatments in preparing container-grown Douglas-fir seedlings for overwinter storage.

Rocky Mountain Douglasfir is hardier, slower growing, shorter-lived and seldom grows over ' tall. The needles are shorter and bluish green, although in some trees may be yellowish green. The cones are barely 3" in length with bracts bent upwards. Douglasfir is written as one word or hyphenated to indicate that it is not a true fir.

41 15 Computer fit of the data from Figures 13 and 14 to the logistic form using. Plant moisture stress (PMS), or plant water potential, indicates the demand for water within a plant. PMS integrates the soil moisture tension in the rooting zone (the water supply), the resistance to water movement within the plant, and the demands for transpiration imposed by the environment (heat load, humidity, wind, etc.).
Before you start growing Douglas firs, you’ll need to find a good planting location. They grow best in areas with cold winters and hot summers in U.S. Department of Agriculture plant hardiness zones 4 through 6.
When you are planting a Douglas fir, be sure to site the tree in an area with excellent drainage. Even the best Douglas fir tree. Use of water stress integral to evaluate relationships between soil moisture, plant water stress and stand productivity in young Douglas-fir trees Article in New Forests 49(6) July with Seedling sshowed the least overall growth in the uncut stand where plant moisture stress reached bar ( MPa) in Douglas-fir and bar ( MPa) in white fir.
Results indicate that a 10 m 2 /ha shelterwood provides conditions for successful 1st-year survival and growth of container-grown Douglas-fir, but a 15 m 2 /ha density is Cited by: The stomata of both white and black spruce were more sensitive to atmospheric evaporative demands and plant moisture stress during the first growing season after outplanting on 2 boreal sites in northern Ontario than were jack pine stomata, physiological differences that favoured growth and establishment being more in jack pine than in the spruces.

Environmental factors (such as light, moisture, nutrients, density, and temperature) and plant physiological factors (such as carbohydrate reserves, hormone levels, frost hardiness, and dormancy) interact to shape growth and survival of coniferous seedlings in nursery fields and after by: Influence of moisture stress and induced resistance in ponderosa pine, Pinus ponderosa Dougl.

Many records from the s and early s indicate that Douglas-Fir regularly grew over feet, and even approached feet. However, these large specimens were logged, leaving the diminished trees of today.
