Does Decoating effect germination over time? Do we have to plant within 72 hours?

30 Samples each a Ryegrass, Fine Fescue, Kentucky Bluegrass Mixture Test A Decoat 12 grams every 2 weeks, dry and plant 400 seeds of each component within 72 hours. Test B Decoat 170 grams of seed initially, dry. Every 2 weeks plant 400 seeds of each component from the bulk amount decoated.

Rule proposal for 2015 would be to change ‘plant within 72 hours’ to? Would most labs go for within 7 days?
