Horticultural Biology, Ph.D. (Ithaca)
Field of Study
Although emphasis is on horticultural plants and systems commonly found in areas of temperate climate, graduate study on species and cropping systems of tropical areas is also possible by use of our extensive greenhouse and growth chamber facilities, and through conduct of thesis research in tropical areas.
Members of the graduate field of horticulture reside in the Department of Horticulture on the Ithaca campus, and at the New York State Agricultural Experiment Station in Geneva. In addition, some faculty members of other departments such as Plant Biology, Plant Breeding, Crop and Soil Science, etc., may also be members of the graduate field of horticulture.
Minor fields of study may be selected from such areas as plant physiology, pathology, anatomy, or ecology; biochemistry; botany; entomology; taxonomy; genetics; education; soils; agricultural, resource, and managerial economics; communication; agricultural and biological engineering; and landscape architecture.
All students receive experience in academic education and Cooperative Extension programs.
At the Ithaca campus, research facilities include laboratories equipped for studies of all aspects of plant physiology, including photosynthesis, pre- and postharvest physiology, biochemistry, biotechnology, photobiology, analysis for chemical elements, and tissue culture. Extensive greenhouse and growth chamber facilities permit varying degrees of plant environmental control. Facilities for postharvest research include rooms for refrigerated and controlled atmosphere storage. Field facilities include two research orchards for study of fruit crops, two vegetable research farms, an outdoor nursery, turfgrass research areas, and the Cornell Botanic Gardens, an extensive botanical garden. At the Agricultural Experiment Station in Geneva, laboratories, greenhouses and growth chamber facilities similar to those in Ithaca are found. In addition, 600 acres of orchards and 200 acres of vegetable experimental farmland are available for research purposes. A wide range of apple, grape, and vegetable germplasm is maintained by the USDA Plant Introduction Station, the National Clonal Repository and the fruit and vegetable breeders. Research is also conducted at the Hudson Valley Lab (fruit research), the Long Island Horticultural Research and Extension Center (grape and vegetable research), and the Fredonia Grape Research Station.

Application Requirements and Deadlines
Fall: Dec 1; Spring: check with field
- all Graduate School Requirements, including the TOEFL Exam for Non-Native English Applicants
- three recommendations
- GRE general test
A strong background in life sciences is important, as evidenced by grades, coursework and research projects undertaken. Three letters of recommendation and the Graduate Record Exam (GRE) is required. For all non-native English speaking students, a minimum TOEFL of reading 20, writing 20, listening 15 and speaking 22 (Internet-based test) is required and a cumulative score is not acceptable. We urge serious candidates to contact our graduate faculty to introduce themselves, to discuss mutual research interests; and if appropriate, to plan a visit to Cornell. All application materials must be received by Dec. 1 for the fall term, or Sept. 15 for the spring term.
The overall goal is to train future leaders in horticultural research, education and outreach in both industry and public landscape spheres.
