WebbIn order for a seed to be stored and survive freezing temperatures, a prerequisite is that it is capable of surviving desiccation or removal of most of the water in its cells. Research from the 1950s and 1960s demonstrated that drying and cooling crop seeds increased survival time (i.e., longevity).
