Description The maintenance of seed viability is a basic requirement
for successful preservation of germplasm. Seeds intended
for storage should have high germinability and viability
should be monitored by periodical germination tests
during storage. Even for the seeds stored under optimal
conditions suitable for long-term storage, viability may
decrease as a result of deterioration processes such as: an
increase of the free radical content, changes in protein
structure, 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 at
different levels resulting in decreased germinability,
production of abnormal seedlings, and even complete
loss of viability....
