Effects of wind induced soil moisture stress on the germination and early growth of Pinus banksiana Lamb. on three soil texture types
(1988)
A controlled environment wind tunnel was used to produce three wind speeds and hence three soil drying
rates in order to study the effects of soil moisture stress on seeds and germinants of Pinus banksiana
Lamb, planted ...
Height, growth and site index of jack pine (Pinus banksiana Lamb) in the Thunder Bay area : a system of site quality evaluation
(1986)
Height growth patterns and site index were studied using stem analyses
taken from dominant and codominant trees growing on 109 plots located in
mature, natural, fully stocked evenaged stands of jack pine {Pinus banksiana ...
Spatial analysis in timber management planning
(1988)
The objective of this thesis was to develop a spatially sound
timber management strategy design tool. Long-range timber management
modelling systems were identified as being limited by the inability to
perform large-scale ...
Characterization, distribution and pathogenicity of bacteria isolated from chlorotic white spruce (Picea glauca (Moench) Voss)
(1981)
Several genera of bacteria were isolated from the foliage,
twigs, bark and wood of stems of chlorotic 10 - 12 years old white
spruce (Picea glauca (Moench) Voss).
Most of the isolates were nonspore-forming, aerobic ...
Competition trials of Pinus banksiana and Populus tremuloides under a range of proportions and densities
(1986)
This study was the -first study designed specifically to
analyse the competitive effects of density and species mixture
for both Pinus banksiana and Populus tremuloides
seedlings during the initial stages of growth and ...
Within and between-species competition and individual tree growth in a young jack pine-aspen stand
(1986)
The competitive relationship between jack pine (Finns banksiana Lamb.) and trembling aspen (Populus tremuloides Michx.) was studied in an 8-year-old mixed stand in North Central Ontario, Canada. During the summer of 1984, ...
Vegetative and sexual phenology, reproductive dynamics and bud differentiation in a clonal seed orchard of white and black spruce
(1981)
To evaluate the importance of phenology and strobilus
production in a clonal seed orchard of white and black
spruce, 14 clones of each species represented by 4 ramets
each, were selected from the Mattawin seed orchard. ...
Foliage and wood production in 17- and 32- year old Pinus banksiana Lamb. of Northwestern Ontario
(1980)
The objectives of this study were 1) to provide information on
the above ground biomass production of young jack pine (Pinus banksiana
Lamb.) stands, and 2) to evaluate the influence of crown foliage stand
density, and ...
Morphological variation in subalpine fir and its relationship to balsam fir in western Canada and the United States
(1988)
To help clarify the taxonomy of the two closely related North American firs
subalpine fir {Abies lasiocarpa (Hook.) Nutt.) and balsam fir {Abies balsamea
(L.) Mill.) in western Canada and the United States, 10 populations ...
