Pollen pool heterogeneity in natural stands of upland and lowland black spruce (Picea marinana (Mill.) B.S.P.)
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 ...
Pollen pool heterogeneity in jack pine (Pinus banksiana Lamb.) : a problem for estimating population outcrossing rate? / Yong-Bi Fu
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 ...

Larix Iyallii Parl, (alpine larch) is a small to medium tree restricted to the timberline zone of the mountainous regions of the Pacific Northwest of the United States and the adjacent southwest of Canada. To examine ...
Genetic variation in growth and yield components of juvenile balsam poplar (Populus balsamifera L.) growing in northwestern Ontario / by Frank Schnekenburger
A nursery and greenhouse study of balsam poplar (Populus balsamifera L.) were carried out in Thunder Bay, Ontario, to study the extent and nature of variation in growth and its relation to the following yield components: ...
