Tropical Seed Science

TPSS 421


Orville Baldos


To study seed sciences as they relate to the seed industries of Hawaii and other tropical locations. Specific objectives are:

  1. Study seed biology and biotechnology.
  2. Become acquainted with seed production, processing, storage and pathology.
  3. Conduct viability, vigor and performance tests of seeds.
  4. Conduct field studies of Hawaii's seed industry.

Skills and knowledge to be acquired:

Students must have a basic background in agricultural and biological sciences, and will be expected to be skilled in use of computer web and library searches. Research reports will emphasize knowledge of plant biology (physiology, genetics, pathology) pertinent to seed production and handling. Field trips will emphasize practical on-farm skills in seed production (agronomy, ecology, mechanization, reproductive biology).

Computer skills to be acquired:
