It is a myth that seed can be fooled into thinking a winter has passed
by simply placing them in the freezer overnight. Many seeds do need a
period of low temperature before they will germinate but this is a
physiological process. They need moisture, oxygen, and a temperature
just ABOVE freezing for several weeks.  These conditions are not 
produced in the deep-freeze. Also the acorns of many temperate oak
species would not survive being frozen to -20 C, even overnight.
