Evaluation of a mini-container accelerated transplant system : the black spruce winter crop
(1986)
The effects of four factors on nine attributes of black
spruce (Picea mariana (Mill) B. S. P.) seedlings were
investigated. The seedlings were produced under an
accelerated transplant system that used a 6 ml Castle ...
Plus-tree selection of black spruce in Northwestern Ontario for Superior growing space efficiency
(1985)
Plus-tree selection of black spruce [Picea mariana (Mill.) B.S.P.)
based on increment of wood volume per unit of crown (growing space efficiency) has the potential to improve yield per hectare and avoid biased
selection ...

Assessing data accessibility and quality: predicting the effect of impervious surfaces on water quality in urban centres on the west coast of Lake Superior
(2020)
This research will critically examine the difference in data quality and
accessibility between two cities through an analysis of predicting the effect of
impervious surfaces on water quality. Through using the Impervious ...
Pollen pool heterogeneity in natural stands of upland and lowland black spruce (Picea marinana (Mill.) B.S.P.)
(1991)
One of the basic assumptions of the mixed-mating model is that
the pollen pool of a population is homogeneous. However mounting
evidence would suggest that a homogeneous pollen pool is not the
norm in populations of ...
