Resumo: The aim of this research was to evaluate the influence of pre-germination treatments on germination and initial seedling growth of Libidibia ferrea. We tested 5 treatments: control; sulfuric acid; water for 24 h; hot water and scarification. We evaluated the percentage of initial growth (%E), speed index (IVE) and mean emergence time (TME). For germination we evaluated the height and stem diameter of the seedlings, number of leaves, leaves, stem and roots dry matter and root/shoot ratio. Sulfuric acid treatment presented higher %E and IVE and lower TME, and it was the treatment that showed the better growth of the plants.

Foram utilizados 5 tratamentos: controle; ácido sulfúrico; água por 24 h; água quente e escarificação. Para a germinação, avaliou-se a porcentagem (%E), o índice de velocidade (IVE) e o tempo médio de emergência (TME) e para o crescimento inicial, avaliou-se a altura das mudas, diâmetro do caule, número de folhas, matéria seca das folhas, caule e das raízes, e razão raiz/parte aérea. O tratamento com ácido sulfúrico resultou em maior %E e IVE e menor TME, apresentando, também, o melhor crescimento das plantas.Embrapa Florestas2018-12-29info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/168410.4336/2018.pfb.38e201801684Pesquisa 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/1684/818https://creativecommons.org/licenses/by-nc-nd/4.0info:eu-repo/semantics/openAccessWalter, Letícia SiqueiraSantos, Cibele Alves dosOliveira, Laura dos SantosSilva, Elaine Cristina Alves da2019-05-10T19:43:48Zoai:pfb.cnpf.embrapa.br/pfb:article/1684Revistahttps://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:2019-05-10T19:43:48Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
