Photosynthetic efficiency of frozen-stored Picea glauca seedlings in relation to root pruning, root growth, and shoot moisture stress / by S. J. Colombo. --
(1981)
This study examines the influence of duration of frozen
storage (-2 C) and root pruning on photosynthetic efficiency,
shoot moisture stress and root growth of white spruce (Picea
glauca (Moench) Voss) seedlings planted ...
Crown dynamics in Pinus resinosa Ait. : analysis and stochastic description of branch production, branch extension growth and foliage dry weight---branch length relationships
(1981)
The development of the crown structure of Pinus
resinosa Ait. was analysed in terms of three component
processes of tree growth: the number of first order
branches per whorl within the crown, the annual extension
increments ...
Post logging succession and vegetation management with hexazinone herbicide in Picea glauca (Moench) Voss-Populus tremuloides Michx. forest
(1981)
The objectives were: to review the successional behaviour of
white spruce (Picea glauca (Moench) Voss) - trembling aspen (Populus
tremuloides Michxt) stands in the literature, to conduct field studies
of the successional ...
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 ...
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. ...
