Considering the goals of this group, I thought you would be interested in a little experiment I am conducting. I obtained some seeds of Sarracenia rubra jonesii from the ICPS seedbank. These were then flash frozen to -196C (liquid nitrogen) and to -80C (ultracold freezer = temperature of dry ice). The seeds were then stratified and planted. Tonight I noticed that the first seeds from both exposures as well as the untreated controls were beginning to sprout. I will keep counts and report on germination rates later. The point of this message is to communicate that seeds can be placed at ultralow temperatures and as such could theoretically be stored for "very long" periods of time.
