Quick Answer
Test seed viability through simple methods like the water test, where seeds that float are likely non-viable, and the paper towel test, which involves soaking seeds in water for 24 hours to check for germination. You can also use the tetrazolium test, a chemical test that stains non-viable seeds. Check seed condition and color to ensure optimal germination.
Preparing Seeds for Testing
Before testing seed viability, prepare the seeds by cleaning and drying them. Remove any debris, dirt, or moisture from the seeds to ensure accurate results. Store seeds in an airtight container to maintain their viability.
The Water Test
The water test is a quick and simple method to assess seed viability. Fill a cup with water and add a few seeds. If the seeds float, they are likely non-viable. Seeds that sink will likely germinate. Use this method for seeds that are large enough to see easily.
Advanced Testing Methods
For more accurate results, use the paper towel test or the tetrazolium test. Soak seeds in water for 24 hours, then check for germination. For the tetrazolium test, mix a tetrazolium solution with water and soak the seeds. Non-viable seeds will turn yellow or brown, while viable seeds will remain white. This method is more accurate for smaller seeds or when a high degree of accuracy is required.
