Mating system and population structure in a black spruce (Picea mariana (Mill.) B.S.P.) clonal seed orchard in Northwestern Ontario
(1985)Multi-locus enzyme systems were studied in a black spruce {Picea maniana (Mill.) B.S.P.) clonal seed orchard in northwestern Ontario. The embryonic and megagametophytic tissues of each clone were sampled and ... -
Patterns of allozyme variation in tamarack (Larix laricina (Du Roi) K. Koch) from northern Ontario
(1988)Roots from approximately 30 trees from each of 44 populations across the range of tamarack (Larix laricina (Du Roi) K. Koch) in northern Ontario were analyzed electrophoretically for allozymic variation in 14 enzyme systems ... -
Pollen pool heterogeneity in jack pine (Pinus banksiana Lamb.) : a problem for estimating population outcrossing rate?
(1990)Pollen pool heterogeneity, which violates an assumption of the mixed-mating model, is one of the major problems facing population geneticists concerned with measuring plant mating systems. In the present study, isozyme ... -
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 ... -
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 ...
