Establishment of Native Species Through Direct Seeding in Piauitinga River - Sergipe

ABSTRACT The direct seeding technique stands out for forest restoration projects due to savings in deployment costs and has been increasingly used. This work was carried out with the objective of assessing emergence, survival and establishment of native forest species, by means of seeds, in riparian areas of Piauitinga River, in the municipality of Lagarto-SE. The species used were Libidibia ferrea var. leiostachya (Benth.) L.P.Queiroz., Cassia grandis L.F., Cecropia pachystachya Trec., Enterolobium contortisiliquum (Vell.) Morong and Guazuma ulmifolia Lam. The field work was performed in a randomized block design (RBD) with four replications in factorial scheme, testing five species with and without treatment for overcoming of dormancy. It was observed that direct sowing is a viable technique for the area of study only for the species L. ferrea var. leiostachya, E. contortisiliquum and Cassia grandis, using seeds with and without dormancy.
