Influence of storage conditions on seed quality of maize, soybean, and sunflower

The study was aimed to examine the changes in seed vigor and oil content in different genotypes of maize, soybean and sunflower over four years (2002-2006) in two type storage conditions differed in terms of air temperature and humidity: 25 C/75% and 12 C/60%, respectively. Affected by storage longevity, on an average, seed vigor decreased for 18, 7% in maize and for 57, 1% in both soybean and sunflower, respectively. Seed oil content decreased for 1, 12% in maize, 2, 27% in soybean and 12, 05% 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 12 C/60%, decline of seed vigor was less for 17% (maize), for 24% (sunflower, soybean)and decreasing of seed oil content was less for 0, 87% (maize, 0, 91% (soybean)and 2, 27% (sunflower) than in storage conditions by 25 C/75%. In summary, the lowest seed quality losses were in maize, then in soybean and the highest losses were in sunflower. Decreasing seed quality losses is possible with providing suitable storage conditions, particularly for soybean and sunflower.
