Abstract

Because the role of tree and shrub seed is indispensable in the renewal of forests and ranges, their identity and quality are critically important. This guide briefly covers recommended practices for maintaining the identity of seeds, for sampling them, and for testing them for quality. Practices associated with the testing and use of tree seed have developed over many years, whereas those for shrub seed are just developing. Selected references, excerpts from official seed testing rules, addresses of seed testing laboratories, and sources of information for shrub seed are included.
