alnifolia (known as the saskatoon) is a native fruit bearing
shrub that has been valued for its flavourful berries since pre-
and early settlement of the Canadian prairies. In the latter part
of this century, the plant has been domesticated with the release
of several cultivars, beginning with 'Smoky' in the 1950s.
a) Growth and yield studies - comparison of tissue cultured and
traditionally propagated plants. Analysis of yield components in
relation to shoot architecture.
b) Microspore and pollen development in saskatoons. A collaborative
project with Dr. Michael Sumner, Department of Botany, University
of Manitoba, using light and electron microscope techniques.
c) Epidemiology of Entomosporium leaf and berry spot disease and
disease forecasting in Saskatoons using meteorological data. This
work constituted the Ph.D project of Quinn Holtslag.
