The process by which an orgranism grows from a seed

3

Seeds have a Life-Span

  • Seed Viability: an indication of whether or not a seed is alive and can reproduce itself

  • Germination Rate: The average number of seeds that will germinate/sprout over a 5-10 day period.

Seed Viability Tests

Ways to test if your seed will grow

13

Water Test

Take your seeds and put them in a container of water. Let them sit for about 15 minutes. Then if the seeds sink, they are still viable; if they float, they most likely will not sprout.


- Limited Reliability. Seed weight can affect the test

Germination Test

  • Take some seeds, and place them in a row on top of a damp paper towel. Fold over the paper towel and place in a zip-up plastic bag and seal it. Put in a warm location, and check the seeds often to see if they have began to germinate and/or to check the moisture of the paper towel. It should be kept damp, be careful not to apply too much water.
