SOCR 201 - Seed Development and Metabolism

  • 1 credit
View available sections

This seed development and metabolism course introduces students to the basic concepts of seed physiology. An understanding of the processes which occur during seed development, maturation, storage and germination is needed to clarify why certain procedures are used for seed germination, why some seeds do not respond to procedures used, and to help analysts explain to customers why their seed is of low quality. Seed composition is a critical factor in how well seed stores or germinates. Stage of seed development and maturity will also influence seed storability, germination and growth.

This course is beneficial for individuals interested in learning about seeds and for those who are studying to become registered seed technologists or certified seed analysts. Individuals registered or certified by the Society of Commercial Seed Technicians or by the Association of Official Seed Analysts are in demand by seed companies and by state and federal seed laboratories.

This course requires proctored exams. Details will be provided in the course syllabus.

Roger D. Levy earned his B.S. in Agronomy from Purdue University and then earned his Ph.D. from the University of Illinois in Genetics. He then went to work as a corn breeder for Gutwein Seed and later for Beck’s Hybrids. During his career he developed an inbred that was used in hybrids that were twice National Champion in the National Corn Growers Association Yield Contest and inbred lines that were marketed by major foundation seed companies. Some of the breeding projects he worked on include cold tolerance, high amylose corn, white corn, and high extractable starch corn. His special interests included developing food grade hybrids for Frito-Lay and Cargill Dry Corn Ingredients and implementing the Dihaploid breeding procedure for high throughput breeding in Beck’s corn breeding program. Some of the committees that he has served on include the Technical Steering Group for the USDA Germplasm Enhancement of Maize program, the Corn Committee for the Indiana Crop Improvement Association, and the Planning Committee for the American Seed Trade Association’s Annual Corn and Sorghum Research Conference. Currently he is a member of the Molecular Genetics Research Committee for Native Traits LLC and the Estes Valley Community Garden board.

Loren E. Wiesner earned his Ph.D. from Oregon State University in 1971. Since that time, he has conducted research in seed physiology on cereals and forage legumes and grasses, developed techniques for establishment of dormant species, and studied the effects of environment on seed dormancy, and the relationship of seed vigor to field establishment of grasses.

Dr. Wiesner has taught courses in seed production and conditioning, and forage crops and seed physiology at Montana State University. He has authored and co-authored more than 67 publications . He has also served as editor of the Journal of Seed Technology and technical editor for Crop Science.
