The ... [Show full abstract] Copaiba (Copaifera langsdorffii Desf - Fabaceae) is a tree species occurring in Brazil, the source of the oil-for-Copaiba. This essential oil has extensive use in folk medicine in humans and animals. The oil has anti-inflammatory and heals wounds ability, according to scientific studies. The occurrence of Copaiba was common in tropical forests, but deforestation reduced the density of mature trees, leaving a few specimens. It's too small to get the index of mature plants from naturally seeds germinated. For this reason many regions no longer have this species. An alternative is to reforestation. For this to be viable, specific techniques must be developed. This study aimed to evaluate the germination of Copaiba subjected to two treatments: T1-(without scarification or natural) and T2 (mechanical scarification) breaking through the cuticle to break dormancy. The two treatments were conducted under experiments conditions with 200 seeds in 10 random blocks by researchers at the University of Mato Grosso, Cáceres (MT), Brazil, from January to April 2006. The results show that seeds subjected to treatment T2 provided a germination rate of six times higher (59.50%) than those from T1 (9.50%). This highly significant difference between treatments revealed that the mechanical scarification (T2) is the best way to break the dormancy of seeds of Copaiba. As a consequence it will be more successful in producing seedlings of this species for purposes of reforestation, seeking to make possible in the future, the continued production of oil-of-Copaiba.
