This work aimed to evaluate the survival rate and quality of the seedlings generated from the study of the reinduction of the desiccation tolerance of A. pavonina. A. pavonina seeds were collected in trees located in Sinop city and were used to calculate germination percentage. A reasonable amount of A. pavonina seeds were sown, and after its primary root protrusion in up to 2 mm root they were placed on plastic box with silica gel for further desiccation in different humidity levels. The treatments were based on the dehydration time which were analyzed in 6h, 12h, 24h, 36h and 48h. Our results show that only the 6h, 12h and 24h treatments were significant in the reinduction of the desiccation tolerance, where the survival rate was higher than 90%. The desiccation treatment in 36h had a survival rate of 18%.
