Field Validation of Laboratory Seedling Testing Results

The Weyerhaeuser Seedling Testing System (STS) has been operational since 1985. Located in Centralia Washington, USA, the laboratory can conduct five types of tests which evaluate: (1) root growth potential (RGP), (2) seedling viability, (3) cold hardiness, (4) morphology and (5) pathogen infection level. About 500 to 800 tests are conducted annually. The seedling testing results gathered at the laboratory are compiled as base-line data for each nursery/species/stock type for interpretation of current and future test results.
