Dr. Richard Zobel, plant physiologist, discusses with Dr. Katherine O’Neill, ecologist, the root growth scanning equipment he is using in an AFSRC greenhouse. There is insufficient information about the pattern of grass seedling root system development. Dr. Zobel is documenting the developmental patterns (Ontogeny) of perennial ryegrass seedling root systems (film clip - WMV file, 2.28 MB).

More information about AFSRC root research can be obtained from Dr. Richard Zobel
