Resumo: This study aimed to evaluate the natural regeneration and the abundance of exotic palms in the understory of a planted forest of Araucaria angustifolia in Viçosa, Minas Gerais State, Brazil. The sample corresponded to 40 plots of 2 m x 2 m. Diameter at ground level of all shrubs and trees with diameter ≤ 5 cm and height ≥ 0.5 m was measured. Phytosociological parameters and diversity indices were calculated. All species were classified regarding its life form, successional class and dispersion syndrome. We sampled 980 individuals that presented higher proportion of shrub species, typical of understory and zoochoric. The exotic species Archontophoenix cunninghamiana, known as Australian palm, presented the third largest importance value, highest dominance and 19.25% of the total basal area, considerably larger than the other species. A. cunninghamiana was characterized as an invasive species that dominate the natural regeneration stratum. Inibition of natural succession by exotic species, such as A. cunninghamiana, should be monitored, aiming at the withdrawal of the problem species what will ensure the succession process.

A amostra correspondeu a 40 parcelas de 2 m x 2 m, onde mediu-se o diâmetro ao nível do solo (DNS) de todos os indivíduos arbustivo-arbóreos com diâmetro ≤ a 5,0 cm e altura ≥ a 0,5 m. Foram calculados os parâmetros fitossociológicos e os índices de diversidade e equabilidade. As espécies foram classificadas quanto à forma de vida, classe sucessional e síndrome de dispersão. Foram amostrados 980 indivíduos, sendo observada maior proporção de espécies arbustivas, típicas de sub-bosque e zoocóricas. A espécie exótica Archontophoenix cunninghamiana, conhecida como palmeira australiana, obteve o terceiro maior valor de importância, a maior dominância e 19,25% da área basal total, valor consideravelmente maior que o das demais espécies. A. cunninghamiana foi caracterizada como uma espécie exótica invasora que domina o estrato de regeneração natural. A inibição da sucessão natural pela presença de espécies exóticas, como A. cunninghamiana, precisa ser monitorada, visando eliminar as espécies-problema, para garantir a continuidade do processo de sucessão.Embrapa Florestas2017-09-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/117710.4336/2017.pfb.37.91.1177Pesquisa Florestal Brasileira; v. 37 n. 91 (2017): jul./set.; 249-258Pesquisa Florestal Brasileira; Vol. 37 No. 91 (2017): jul./set.; 249-2581983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1177/584https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessCardinelli, Lucas SiqueiraFonseca, Rúbia SantosMartins, Sebastião Venâncio2018-05-24T12:03:03Zoai:pfb.cnpf.embrapa.br/pfb:article/1177Revistahttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/PUBhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/oaipfb@embrapa.br || revista.pfb@gmail.com || patricia.mattos@embrapa.br1983-26051809-3647opendoar:2018-05-24T12:03:03Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
