Developed by University of Guelph at Horticulture Research Station, Simcoe. Made by Dr. John Cline.

Dr. John Cline is a professor in the Department of Plant Agriculture, University of Guelph where he teaches undergraduate and graduate students and conducts research in tree fruit pomology. He also provides outreach in various capacities to the tree fruit industry.


The primary objectives of Prof. Cline’s research is to investigate factors that determine yield and fruit quality of tree fruit crops. Projects include investigating the use of new, size-controlling apple, peach and cherry rootstocks, research on European apple cultivars and red-fleshed crab apples for hard cider, irrigation scheduling, and studying horticultural technologies to reduce labor inputs in a movement toward greater orchard automation. Additionally, his research spans the investigation of plant bioregulators to regulate flowering, plant growth, improve fruit quality and reduce pre-harvest fruit drop. His orchard and lab research is carried out at the University of Guelph, Simcoe Research Station and on commercial orchards across Ontario.


John holds a B.Sc. in soil science (Univ. of Guelph), M.Sc. in horticulture (Michigan State University), and a Ph.D. in Horticulture (University of London, UK). Further details about his program can be found at
