It was demonstrated that when onion seeds were stored under five different conditions, the longevity of the seeds and the accumulation of chromosomal aberrations in the seed survivors are both influenced by time of storage, storage temperature and seed moisture content. Seed longevity is extended and the frequency of the aberration is decreased by lowering the temperature or the moisture content and shortening the storage period. There is a linear relationship between the percentage of seed viability and the mean frequency of aberrant cells observed in the root tips of surviving seeds (plotted on a probability scale). This suggests that for any given percentage of seed viability, the frequency of the aberration can be predicted and it is the same, regardless of the combination of storage conditions leading to loss of viability.
