Dr. Gerald Deitzer Emeritus Associate Professor
|
 |
Education:
- Ph.D. in Botany from the University of Georgia, Athens, GA, 1971.
- B.S. in Biology (Pre-Med) from State University of New York at Buffalo, Buffalo, NY, 1966.
Area of Specialization:
- Molecular Genetics of Floral Induction.
Among the most important fundamental questions in plant biology is how the environmental signal that initiates reproductive development is transduced. Dr. Deitzer's laboratory is currently undertaking a molecular genetic approach to answer this question. http://www.agnr.umd.edu/maes_exe/dividends/deitzer1.pdf
- Photoperiodic Regulation of Flowering in Strawberry.
Courses:
- PLSC201: Plant Structure and Function
- PLSC400: Environmental Plant Physiology
- PLSC683: Light and Plant Development
