Abstract

SILVA, Kelly de Almeida; MARTINS, Sebastião Venâncio; MIRANDA NETO, Aurino  and  CAMPOS, Wanuza Helena. DIRECT SOWING WITH TRANSPOSITION OF LITTER AS METHODOLOGY OF ECOLOGICAL RESTORATION. Rev. Árvore [online]. 2015, vol.39, n.5, pp.811-820. ISSN 0100-6762.  http://dx.doi.org/10.1590/0100-67622015000500004.

of ecological restoration of degraded areas. The study was conducted in the Nursery Research at Federal University of Viçosa (UFV) in the open construction site, with a completely randomized design. We compared three different treatments with five replicates each, leaving also five plots as control. For the control plots only the topsoil from the construction site was removed. The other treatments consisted of direct sowing of four native species, two pioneers (Senna macranthera and Colubrina glandulosa) and two non-pioneer (Tabebuia serratifolia and Cedrela fissilis). Treatment 1 consisted of only direct sowing, treatment 2 of direct sowing with subsequent transposition of litter and treatment 3 of transposition of litter with subsequent direct sowing. The litter has been transposed from a fragment of secondary semi deciduous forest located on the campus of UFV. After two years, treatment 2 had a higher percentage of emergency of seedlings. In treatment 1 36 individual trees were found, only from sowing. In treatment 2, there were 312 individual trees and in treatment 3, 140 individuals, both with individuals from sowing and litter transposed. The transposition of litter influenced seed emergency and plant establishment. S. macranthera and C. glandulosa were the species with the highest percentage of emergency and, therefore, have potential for use in ecological restoration projects through direct sowing.
