Seed quality testing of native species

Testing native seed quality before planting cannot be overemphasized. Planting high quality seeds is the cornerstone for successful field emergence. The increasing use of seed certification for native species further emphasizes the need for accurate seed testing. Our objective in this article is to provide a summary of principles and procedures for some useful seed quality tests for natives and other species. Testing for physical purity and viability of seeds are the two most important tests needed to avoid weed problems and poor stand establishment. Other seed quality tests such as vigor tests, x-ray, and seed moisture content provide useful information about the quality of the seeds.
