Departmental Graduate Studies Manual
Our Horticulture Graduate Students
Graduate study for M.S. and Ph.D. degrees in Horticulture is available to qualified students who have an undergraduate degree from accredited institutions in horticulture, or in related plant sciences including botany, crop science, environmental sciences, or professions related to landscape design. Non-plant science degree applicants with substantial experience in related professions may also qualify.
Applicants seeking graduate degrees in horticulture should have adequate preparation in the fundamental sciences (biology, chemistry, biochemistry, statistics, physics), as well as undergraduate course work in the plant sciences (e.g., agronomy, botany, ecology, horticulture, genetics, plant physiology, plant pathology, plant anatomy). Applicants lacking adequate preparation may be accepted conditionally, with the provision that recommended undergraduate courses be completed before the degree is awarded.
The graduate admissions committee accepts only those students who provide acceptable GRE and TOEFL scores, transcripts, letters of reference and a professional goals statement that show potential and promise to complete the requirements for the degree being sought. All students applying for admission to the M.S. and Ph.D. Horticulture program are expected to take the Graduate Record Examination (GRE).
Research Opportunities
Research training, academic guidance and career counseling are provided by faculty in the department, the College of Agricultural Sciences, and interdisciplinary graduate programs such as the Cell and Molecular Biology Program, the Graduate Program in Food Science/Safety, the Graduate Degree Program in Ecology, and the Program in Molecular Plant Biology.
Research options include opportunities to concentrate on laboratory, field, greenhouse or landscape design projects. The environment created by cooperation between faculty involved in applied and basic research and extension allows students to develop a broad professional science and applied horticultural base.
Topics for thesis or dissertation research
Topics for thesis or dissertation research are determined through consultation with the student’s adviser and graduate advisory committee. Research may have a crop focus, but should also have a discipline (e.g. plant physiology, environmental and soil sciences, plant genetics, plant biochemistry, landscape design/planning) emphasis. The table below lists a number of topics and the advisers who have worked with graduate students. There is ample opportunity to obtain multidisciplinary research training through faculty in other departments and across campus. The lists to the right below provide links to several interdisciplinary programs and affiliated programs both within the department and beyond.
