Update on Annual Ryegrass
The AOSA approved a change to the germination testing rule for annual ryegrass. This change allows us to end a test early if it has reached maximum germination. As a result, we expect to issue many final test reports on first count. The process will be:
Planting: Samples will be planted within 1-3 days from sample arrival. The planting date will be available on the eCertification website.
Chilling: Samples will be chilled for 7 days to break dormancy. Chilling is critical for uniform and maximum germination.
First Count: 7 days after chilling ends, samples are evaluated as follows:
|End at first count & issue final germination-fluorescence report.|
|End at first count & issue final germination-fluorescence report UNLESS customer requests add’l 7 days by indicating on sample certificate: "14 day germ if TFL is low"|
|Maximum germination but test fluorescence lower than 2% of VFL (does not meet Certification standard)||Keep add’l 7 days UNLESS customer requests on sample certificate: “end on max germ”|
|No maximum germination||Keep add’l 7 days.|
