Resumo: | Pinus plantations cover approximately 1.6 million ha in Brazil. Since pines are considered to be alien invaders with the potential to modify natural environments, the aim of this study was to evaluate seed dispersal, establishment and control of Pinus taeda L., in order to characterize its biological invasion potential under different situations. We studied the dispersal/viability of pine seeds at 25 m, 50 m, 75 m, 100 m, 125 m and 150 m for from the border of a commercial stand, in North, South, East and West directions. Besides, 800 seeds of this species were sown in 11 different sites, ranging from a preserved natural forest to open habitats, in order to evaluate the regeneration potential. Regrowth was also monitored in stumps cut at 10 cm above ground, in well drained or moist sites. Seed dispersal and germination were higher in the South direction and up to 25 m. In the preserved forest no seed germinated, probably due to low light incidence, while in more open habitats they not only germinated but also established. Regrowth was not observed under any studied condition. |

Suas espécies são tidas como exóticas invasoras, ou seja, apresentam potencial para modificar ambientes naturais. Procurou-se caracterizar os aspectos de dispersão, estabelecimento e controle de Pinus taeda L., a fim de avaliar o seu potencial como espécie invasora sob diferentes condições. Foi estudada a dispersão/viabilidade de sementes de P. taeda nas direções Norte, Sul, Leste e Oeste, distantes da bordadura de um povoamento comercial da espécie a 25 m, 50 m, 75 m, 100 m, 125 m e 150 m. Foi avaliada a germinação em ambiente de floresta preservada e em ambientes com maior incidência de luz em 11 diferentes locais, sendo distribuídas 800 sementes a lanço. A rebrota foi avaliada em árvores cortadas a 10 cm do solo, tanto em locais bem drenados quanto em locais mais úmidos. A disseminação e germinação de sementes foram maiores na direção Sul e até 25 m. Constatou-se que na floresta natural clímax, sem luz e no sub-bosque nenhuma semente germinou. Nos locais com maior luminosidade e umidade do solo mais uniforme durante todo o ano as sementes germinaram e se estabeleceram. Não foram observadas rebrotas nas árvores cortadas.Embrapa Florestas2018-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/165110.4336/2018.pfb.38e201801651Pesquisa Florestal Brasileira; v. 38 (2018)Pesquisa Florestal Brasileira; Vol. 38 (2018)1983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/1651/816https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessBognola, Itamar AntonioLavoranti, Osmir JoséHiga, Antonio RioyeiCoutinho, Rodrigo ToledoBobko, AndersonRibas Junior, Ulisses2019-05-10T19:43:46Zoai:pfb.cnpf.embrapa.br/pfb:article/1651Revistahttps://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:2019-05-10T19:43:46Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
