An experiment was conducted to study the most appropriate seeds at the time of processing of the barley (Hordeum vulgare L.) (Sahra cultivar), sorted by gravity separator machine. Experiment formed in completely randomized design with six replications and performed in field and laboratory of Karaj IslamicAzad University at summer in 2015. Treatments consisted of four separate output of gravity separator and sample before conditioning as control. Measured Characteristics of germination included germination rate, germination percent, shoot length (cm), root length (cm), germination characteristics after accelerated aging test, purity and thousand seed mass. All testes were according to ISTA method. Based on the results, thousand seed mass, seed purity, field germination rate and percentage, shoot and root length there was a significant difference in the aging test. No significant difference was observed in standard germination test on the shoot and root length. Also field germination rate was highly significant, the highest germination rate was related to the control treatment, it was about 55. According to observe effects it can be concluded that the seed conditioning by Gravity separator impact on increasing the purity of seeds.
