In humid regions, the major factor contributing to loss of seed viability is lack of adequate drying. Seeds (and other dry commodities) must be dried soon after harvest to preserve quality. Once dry, they must be packaged to prevent reabsorption of water due to ambient high humidity. We have termed this the “DRY CHAIN” in analogy to the cold chain for fresh produce. However, once dry products are hermetically packaged, they do not need to be refrigerated and no further energy input is needed to maintain their quality during storage.
