Accelerated aging test
3 replications of 100 seeds from each treatment and replication was counted; the seeds were placed on net which installed on the water containing boxes. The containers were kept at 41ºC for 72 hours then the standard germination test was done and the numbers of normal seedlings were counted (ISTA, 2008).
