Why does CPC recommend drying seeds at 25-35% RH and 25C for long term storage in the freezer?

Dr. Christina Walters and Lisa Hill, National Laboratory for Genetic Resources Preservation, Fort Collins Because research has shown that seeds will last best when stored at a relative humidity(RH) of 15-25% it is important to understand how the initial RH will respond to temperature changes. In this video, Lisa Hill of the National Laboratory for Genetic Resources Preservation […]
