Survival of dry and ultra-dry seeds of carrot, groundnut, lettuce, oilseed rape, and onion during five years' hermetic storage at two temperatures






Seed Science and Technology 24(2): 347-358

Survival of dry and ultra-dry seeds of carrot, groundnut, lettuce, oilseed rape, and onion during five years' hermetic storage at two temperatures

Since 1974 the advice for genetic resources conservation by long-term seed storage has been to store seeds dry at 5 +or- 1% moisture content at a temperature of -18 degrees C or less. Investigations were carried out to determine whether or not hermetic storage at lower moisture contents (those in equilibrium with about 10% RH at 20 degrees C) would provide better seed survival, particularly in circumstances where refrigeration cannot be provided.
