Genetic variation In traits potentially affecting the waterrelations of balsam poplar (PopuIus balsamifera L.) clones from four provenances along a transect from northern Wisconsin to Pickle Lake in northwestern Ontario ...

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 ...

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 ...
