Vigor Test
Links | |
The seed vigor test is useful for many areas in Seed Science and Technology.
 | Establish seed quality standards (speed and uniformity) |
| Clarify differences in seed vigor among varieties |
| Test under stress, different climates, regions, and treatments |
| Inventory management |
We have been developing a computerized system for assisting seed analysts for
testing seed vigor of various crops. Strength of our system includes the
following aspects.
| Objective tests can be performed. |
| One score in [0, 1000] range (representing speed and uniformity of growth) is computed. |
| Human-in-the-loop system: An interactive system in which analysts verify
the computer output and correct errors, if any. |
| Test results and images can be saved for future analysis and references. |
