Genetic variation in the frost hardiness of Pinus banksiana Lamb. (jack pine) in Northwestern Ontario
To estimate the level and pattern of variation in frost hardiness,
artificial freezing tests of 64 provenances of jack pine were conducted.
The provenances originated from northern Ontario. Seedlings of the
provenances ...
Spatial genetic structure within four tamarack (Larix laricina (Du Roi) K. Koch) populations in Northwestern Ontario
(1989)
This study was conducted to test the null hypothesis
that tamarack (Larix laricina (Du Roi) K. Koch) populations
are random assemblages of genotypes, and that this absence
of pattern can be observed on sites with ...
Phenotypic variation in cone and needle characters of Pinus banksiana Lamb. (jack pine) in Northwestern Ontario
(1990)
To assess the patterns of phenotypic variation in cone and
needle characters of jack pine relative to spatial, climatic and
ecological data, collections were made from ten trees in each of 64
sites in northwestern ...
