Effect of storage longevity under different storage conditions on seed vigor and oil content in maize, soybean and sunflower

The study aimed to examine the changes in seed vigor and oil content in different genotypes of maize, soybean and sunflower over three years (2002-2005) in two type storage conditions differed in terms of air temperature and humidity: 25C/75% and 12C/60%, respectively. Affected by storage longevity, on an average, seed vigor decreased by 13.5% in maize and by 26.5% in both soybean and sunflower, respectively. Seed oil content decreased by 0.58% in maize, 1.68% in soybean and 8.04% in sunflower. Differences in seed vigor and oil content affected by storage longevity were significant among tested crops and genotypes into crop. Storage longevity was negatively associated with seed vigor and oil content. At storage conditions by 12C/60%, decline of seed vigor was less by 7% (maize), by 11% (sunflower, soybean) and decreasing of seed oil content was less for 0.25% (maize), 0.53% (soybean) and 1.75% (sunflower) than in storage conditions by 25C/75%. In summary, the lowest seed quality losses were in maize, followed by soybean and the highest ones in sunflower. Decreasing seed quality loss is possible with providing suitable storage conditions, particularly for soybean and sunflower.
