The Effect of Storage Time and Temperature on Germination of Onion (Allium cepa L.) Seeds

Seed deterioration defined as a decrease in seed quality, viability, and seed germination due to aging or the effect of inappropriate environmental factors. In addition, senescence may be considered as a gradual decrease in biological performance with the risk of increasing changes that lead to seed decay and eventually death over time. The decrease in seed viability due to aging has been attributed to a set of metabolic defects that occur in embryonic and non-embryonic structures. Storage temperature and moisture content are important factors affecting seed longevity. Generally, moisture content is more effective than temperature. One of the main limitations of onion cultivation is the low availability of high-quality seeds at the time of cultivation, which is due to the poor storability of onion seeds in the environmental temperature and relative humidity.
