摘要

Testing of native species lends many problems to seed analysts across the United States. Besides purity and germination decisions, there is also confusion encountered when reporting seed testing results. The Rules for Testing Seeds of the Associationof Official Seed Analysts (AOSA, 2000) require a four-part purity analysis, incorporating Handbook 25, Uniform Classification of Weed and Crop Seeds (AOSA, 1999), for determining what is other crop or weed seed. This causes problems for the analyst andthe consumer. A three-part purity analysis as used by International Seed Testing Association (ISTA, 1999) combines both crop and weed seeds under one classification 'other species', which alleviates many of the problems encountered in reporting seed testresults. Combining other crop and weed contaminates into one classification, which is represented as a single percentage, other species, on the label would harmonize seed trade around the world.
