Dr. Cline teaches and conducts research in pomology, and provides outreach to the industry, growers and stakeholders.
The primary objectives of the pomology research program are to investigate factors that determine the yield and fruit quality of tree fruit crops. Projects include investigating the use of new, size-controlling apple, peach and cherry rootstocks, irrigation scheduling, studying advanced horticultural technologies including new orchard training systems, and investigating plant bioregulators to regulate flowering, plant growth, improve fruit quality, fruit thinning and reduce pre-harvest fruit drop. He also conducts research on the horticultural and juice attributes of cider (alcoholic version) and how cultural management affects fermentation and final product. His research is carried out at the University of Guelph, Horticultural Experiment Station, Simcoe and on commercial orchards across Ontario.
Cline holds a B.Sc in soil science (University of Guelph), an M.Sc in horticulture (Michigan State University), and a Ph.D in Horticulture (University of London, UK).
