Dr. Loren Wiesner
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.
