In the seed testing laboratory we can overcome most cases of dormancy thereby producing results that will correlate with field emergence next spring. The seed is exposed in the germination test to either a pre-chill period of 3 or more days depending upon the severity of the dormancy or by using a growth hormone or growth stimulant known as Potassium nitrate (KNO3)
Extended testing is required
This year we have to extend pre-chill periods with a mid-chill period. The mid-chill is a 3 day chilling after the first count, and is used if high counts of dormant or fresh seeds are observed. For this reason samples using this method take approximately 3 to 4 days longer.
Dormancy should diminish with time
As the season progresses, the dormancy will decrease or disappear completely because storage of seed in cold conditions such as bins or Quonsets helps to combat this phenomenon. Eventually, nature will take its course and allow the seed to reduce its respiration rate which in turn allows the seed to mature.
Our objective, as always, is to provide our clients with the best possible results, so if you are experiencing a delay, rest assured that we are taking all the necessary steps to ensure that you are getting the best possible germination.
If you are using our website to stay current with your results, there will be a remark noting if your sample has been extended or retested.
