Abstract

To examine and evaluate the variation and process of deterioration of accessions of Medicago sativa seeds, which saved in Natural Resources Gene Bank, this experiment were carried out using 22 accessions. All of the accessions were examined in a complete randomized design with three replications under two different conditions, germinator and glasshouse. The recorded traits of the germinator test included, germination percentage (G.P.), speed of germination and vigor. The recorded traits of the test in glasshouses included G.P., speed of germination, plant height, number of tillers and root length in 40 days after planting. Significant differences were found among accessions for most of the traits. Variation among accessions was significant in one or both of the environments. The results of correlation coefficient study showed that speed of germination, could be a very good indicator of seed vigor. Negative correlation was found between reduction of G.P., speed of germination and seed vigor in germinator condition and G.P., speed of germination, plant height and root length in glasshouse condition. Therefore, seed deterioration not only reduces G.P, but also decreases the speed of germination and seed vigor. In all of the Medic ago sativa accessions, G.P. of stored samples of each year was different from other years, therefore reduction of G.P., was highly affected by origin of accessions. It was not possible to differentiate between the effect of maintaining condition and origin of seed. It is suggested that, for better Gene bank management, accessions, have to be considered as regeneration units of collected seeds.
