September 2010 Update
OSU Seed Laboratory Update, September 3, 2010
Adriel Garay, Seed Lab Manager
Reflecting the late harvest, samples arrived about 10 days later than normal. August looked like the usual
busy “peak” season. Sample testing has been moving smoothly. For ease of use and faster options, please
see the points below.
Web sample entry
Almost half of the samples that we receive are being entered on the web by customers ahead of
time. This option provides several advantages: it allows the customer to check for certification eligibility
of the seed lot, it eliminates potential errors caused by interpretation of handwriting, and these samples
move more quickly into testing. We recommend that our customers become web customers. If you are
interested, please check online at http://web.oscs.orst.edu/online/ or contact our office.
Purity testing is flowing well with just an average of just two days for turn-a-round time. For
those in an extreme hurry, rushes can generally be reported the same day if ordered early in the day.
Customers having high inert problems in tall fescue need to pay attention to light-weight blanks. In
perennial ryegrass, pay attention to blanks and multiples. If you have inert problems, call the lab (ask for
Adriel or Ben) for help.
Web customers can now see what day their samples have been planted and whether samples are
being chilled or not. This allows you to estimate when to expect the weekly counts and projected end
date. Weekly counts and final results can also be seen on the web.
Samples that are not chilled are showing lower total germination compared with chilled samples.
Typically, on new seeds, we quit chilling annual ryegrass at the end of September and perennial ryegrass
on January 1st; we stop chilling tall fescue after one year and Kentucky bluegrass and bentgrass after two
years. The lab is collecting data to propose a rule to allow labs to end the germination test of annual
ryegrass before 14 days.
This year we tested ploidy on leaves of annual ryegrass from the production fields for OECD. We
also used TZ to assess viability while germination and fluorescence testing was in process. This process
worked well for the lab and hopefully it helped our customers.
We encourage our clients to use remote printing of our reports. Forty-six clients can now print
their test reports in their own offices and at their convenience. Customers listed on the sample can see
real-time test results for their samples (including weekly germination counts) on the web. For these
options, please contact us at firstname.lastname@example.org.
The Lab has authorized ISTA samplers in Oregon and Washington to respond to customers
needing ISTA Orange Certificates. ISTA Blue Certificates can be issued on most existing
certification and company samples. Australia accepts Orange Certificate and OSU reports.
