Re: HYB: germination experiments/cold climate


For those of us that plant outside--Is it possible we could trick the seed by putting them in the refrigerator after collection, and then planting outside in pots normally?? Virtually eliminate second year germination?? 

Betty-KY- where we are under an ice storm warning.? 



7 months of chilling to germinate? Could 7 continuous months of chilling be equivalent to two winters of 3 1/2 months??

After leaving ungerminated seeds in the fridge another month (after a day every other week at room temperature), I gave up on any more seeds germinating this winter.?
?
But as I was planting them in pots to spend the rest of the winter outdoors (unlikely to get below low 20s F the rest of this spring), I noticed several seeds <finally> starting to germinate in one more cross.?

Or were those few days in between at room temperature enough to fool those stubborn seeds!?
?
Chuck, others in cold climates, how many months do you have outdoor low temperatures below 40oF (4oC)? (? do seed temperatures below freezing count?)?
