The Tetrazolium Estimated Viability Test for Seeds of Native Plants
The demand for seed and planting stock of native species has grown substantially over the past several years. The demand is driven by federal and state agencies, conservation groups and the public that want to use the plants for a wide range of land management applications. Seed producers and nurseries need clean, viable, high quality seed of native species. Seed testing is an important component in the production process of these seeds and test results can be used to manage a variety of activities. One of the tests commonly used to evaluate seed viability of native plant species is the tetrazolium or TZ test. The TZ test is accurate and can be conducted within a few days by an experienced analyst.
