aging in orthodox seeds is a problem

seed deterioration is loss of seed quality, viability and vigor due to effect of adverse environmental factors. many of our crops are reproduced through seeds, and throughout the world large quantities are produced, stored and transported. seed ageing during storage may cause retardation of field establishment, and may eventually result in seedling abnormalities or even failure of emergence. during storage in gene banks, seed ageing may result in loss of genetic diversity. extending and predicting the longevity of stored seeds is therefore highly relevant from a biodiversity as well as from an economic and social point of view. seed rich in lipids has limited longevity due to its specific chemical composition. during storage of oily species declining trend of total oil content and seed germination can be observed. a fatty acid composition is the most important factor which determines oils susceptibility to oxidation regardless of the problems which can be encountered due to the lack of space with favourable conditions, one must always keep in mind that seed is a living organism in which many biological processes, which can damage the seed and reduce its quality, take place, especially when the oily seed is in question
