Abstract:

Seeds of ten crops with various levels of vigor were obtained by treatments under natural or accelerated aging conditions. The seeds were examined for their lipid contents and for their fatty acid compositions. The so far examined crops could be classified into two groups:

1. High lipid content (HLC) seeds, in which no changes, or an increase in the amount of lipids, was noted during the aging process. No significant changes in the fatty acid compositions in this group could be detected.
2. Low lipid content (LLC) seeds, in which the aging process was followed by a decrease in the amounts of the lipid fractions. Those seeds exhibited significant changes in the fatty acid compositions. The sources of these changes are discussed.
