M.S. (HORT)

Areas of Concentration: Genetics and plant breeding of fruit crops or vegetable crops; physiology and culture of fruit crops, vegetable crops, or ornamental crops; physiology and management of turfgrasses.

The Department of Horticulture offers a thesis and non-thesis option for the M.S. degree. The nonthesis program was developed for continued and advanced education in horticulture management. The program is directed toward students entering careers in horticulture upon completion of the degree, or students requiring additional education for advancement in their careers.

Prerequisites to Master of Science Degree Program - Thesis Option: A candidate must have a B.S. degree from an accredited institution with a background in physical and biological sciences, horticulture, and supporting agricultural disciplines. The student will be assigned a major adviser, who will arrange a committee to evaluate the student's background and plan a program of study with the student.

Requirements for the Master of Science Degree - Thesis Option: A minimum of 24 semester hours of graduate level course work and 6 hours of thesis are required, in addition to any deficiency courses that may be specified. The student's advisory committee will also serve as the thesis and oral examination committee.

Prerequisites to Master of Science Degree Program - Non-thesis Option: Students seeking to pursue the nonthesis option must meet all admission criteria for the UA Graduate School. Applicants should have completed a BS or BA degree, and have had course work in plant sciences, biology, botany, horticulture, or 3 years of experience in a plant science related career. Additionally, students seeking admission into the MSHORT program must submit 3 letters of reference regarding academic and professional experiences and potential. No professional examinations are required for admission.

Requirements for the Master of Science Degree - Non-thesis Option: A minimum of 30 hours of graduate course work as approved by the student's academic advising committee and within the requirements prescribed below. Specific Degree Requirements follow:
