Resumo: | Mixed reforestation with native species can establish a process of ecological succession in disturbed or degraded areas, with natural regeneration as one of the most important indicators of progression of ecological succession. In this sense, this work was carried out with the objective of evaluating the composition and phytosociological structure of the natural regeneration in a mixed reforestation area with native species in the municipality of Laranjeiras, SE. In a reforested area of 46 ha, 30 plots of 1 x 1 m were sampled, all individuals with a base height circumference < 15 cm and in the following height classes were sampled: 0,30 m ≤ H ≤ 1,0 m; 1,1 m ≤ H ≤ 2; 2,1 m ≤ H ≤ 3 m. The species were classified according to the ecological group to which they belong and their dispersion syndromes. The parameters of the vertical and horizontal structure, the indexes of diversity and equability and the floristic similarity between the planted species and the natural regeneration were analyzed. The species G. americana and S. terebinthifolia are indicated as facilitating species for the restoration of degraded areas in the Atlantic Forest in the State of Sergipe, as they occurred in the three height classes. A predominance of pioneer species, low diversity in natural regeneration was verified, caused by grazing of horses in the area. There was little floristic similarity between the regenerants and the planted tree species, since the planted adult individuals did not reach reproductive age yet. |

Neste sentido, este trabalho buscou avaliar a composição e estrutura fitossociológica da regeneração natural em uma área de reflorestamento misto com espécies nativas no município de Laranjeiras, SE. Numa área reflorestada de 46 ha foram alocadas 30 parcelas de 1 x 1 m, foram amostrados todos os indivíduos com circunferência na altura da base < 15 cm e nas seguintes classes de altura: 0,30 m ≤ H ≤ 1,0 m; 1,1 m ≤ H ≤ 2; 2,1 m ≤ H ≤ 3 m. As espécies foram classificadas quanto ao grupo ecológico a que pertencem e a suas síndromes de dispersão. Foram analisados os parâmetros da estrutura vertical e horizontal, os índices de diversidade e equabilidade e a similaridade florística entre as espécies plantadas e a regeneração natural. As espécies G. americana e S. terebinthifolia são indicadas como facilitadoras para a restauração de áreas degradadas na Mata Atlântica no estado de Sergipe, pois ocorreram nas três classes de altura. Verificou-se um predomínio de espécies pioneiras, baixa diversidade na regeneração natural, ocasionadas pelo pastejo de equinos na área. Houve pouca similaridade florística entre os regenerantes e as espécies arbóreas plantadas, pois os indivíduos adultos plantados ainda não atingiram idade reprodutiva.Universidade Federal Rural da Amazônia/UFRA2018-09-21info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/2779Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 61 (2018): RCARevista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 61 (2018): RCA2177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
