What is required to retest seeds that previously failed a germination test?

To retest seeds that previously failed a germination test, a retest must be conducted within specific time limits. This requirement ensures that seeds are evaluated under conditions that are relevant to their current viability. The time limits are designated by the regulations to maintain standards for seed quality and to provide an accurate assessment of germination potential.

The specific timing for retests is crucial because seed viability can change over time due to factors like aging, storage conditions, and environmental influences. By establishing a timeframe for retests, the regulations aim to ensure that tests are meaningful and reflect the true germination potential of the seeds in question.

In contrast, producing a new batch, reviewing growing conditions, or cleaning the seeds do not directly address the need for timely retesting according to the established guidelines, which focus specifically on the testing frequency and conditions affecting seed viability.
