Seed viability

A viable seed has the potential for germination when given the required external conditions. Its viability therefore, indicates the activity of the seed internal organ, that is to ascertain whether the seed is alive or not. Most seeds remain viable until the next growing season or period but, many can remain dormant for a number of years until conditions are favorable for germination.

In general, viability of a batch or seed diminishes with time; its maximum viability period depends largely on the species. For example, certify seed quickly loses viability after the first season, but wheat has been reported to have germinated after scores of years. The germination potential of any seed batch will depend mostly on the storage condition of the seeds, which should be cool and dry condition, slowing down the respiration and maintaining the internal status of the seed.

There are conditions that are achieved in commercial seed storing, these are means of sensitive control equipment and packaging of the seed for sale purposes takes account of these requirement and often includes a water proof lining to the packet, with a maintain constant water content in the seed.
