RT Journal Article SR Electronic T1 Seed Quality Testing of Native Species JF Native Plants Journal JO NATIVE PLANTS JOURNAL FD University of Wisconsin Press SP 15 OP 19 DO 10.2979/NPJ.2006.7.1.15 VO 7 IS 1 A1 Sabry Elias A1 Adriel Garay A1 Lee Schweitzer A1 Sherry Hanning YR 2006 UL http://npj.uwpress.org/content/7/1/15.abstract AB 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.
