Seeds intendedfor storage should have high germinability and viabilityshould be monitored by periodical germination testsduring storage. Even for the seeds stored under optimalconditions suitable for long-term storage, viability maydecrease as a result of deterioration processes such as: anincrease of the free radical content, changes in proteinstructure, depletion of food reserves, acidification of fat,changes in enzymatic activity, membrane damage,chromosomal changes and an increase in respiration(Justice and Bass 1979). These processes manifest atdifferent levels resulting in decreased germinability,production of abnormal seedlings, and even completeloss of viability
