Resumo: http://dx.doi.org/10.5902/198050986630Anadenanthera macrocarpa (Benth.) Brenan is a tree species belonging to the family Leguminosae-Mimosoideae which is popularly known as mimosa-black. It features characteristics of early successional, natural occurrence in Brazil and can form clusters almost homogeneous, with great potential in the recovery of degraded areas. This study was conducted at the Center for Agricultural Sciences, University Federal of Alagoas state, aiming at the physical and morphological characterization of seeds, describing the various stages of post-seminal development, and to evaluate various conditions of temperature and substrate to perform the test germination. The seeds were manually extracted, then homogenized, where two samples of 50 seeds were used to determine the initial moisture. Another sample, consisting of eight repetitions of 100 seeds was used to measure the biometry and the number of seeds per fruit. The morphological characterization and the seeds were immersed in distilled water to allow the cuts to the observed structure in microscopes. In the post-seminal study, it was observed the daily processes of seedling growth in rolled paper filter and constant temperature of 30 °C. To assess the germination behavior, the constant temperatures of 15°C, 25° C, 30° C, 40° C and 20-30° C as well as the paper and the sand substrates were tested and it was evaluated the percentage, the rate of germination, the relative frequency distribution, and the tests conducted in a randomized design in factorial 5 x 2 (x substrate temperature) with four replicates of 25 seeds, and the averages compared by Duncan 5% probability. The fruits of black angico show great variation in the seed number per fruit. The embryonic axis occupies part of the central region of the seed with axial and linear positions. The germination is epigeal and the seedlings are fanerocotylar. The temperature determines the 30 ° C and the filter paper substrate provided higher average percentage and germination rate.

Brenan é uma espécie arbórea, pertencente à família Leguminosae- Mimosoideae, sendo popularmente conhecida como angico-preto. Possui característica dos estádios iniciais da sucessão, ocorrência natural no Brasil, podendo formar agrupamentos quase homogêneos, com grande potencial na recuperação de áreas degradadas. O presente trabalho foi conduzido no Centro de Ciências Agrárias da Universidade Federal de Alagoas, objetivando a caracterização física e morfológica das sementes, descrição das diferentes fases do desenvolvimento pós-seminal, bem como avaliar diferentes condições de temperaturas e substratos para a realização do teste de germinação. As sementes foram extraídas manualmente, em seguida homogeneizadas, onde duas amostras de 50 sementes foram usadas para a determinação da umidade inicial. Uma outra amostra, composta por oito repetições de 100 sementes, foi utilizada para a medição biométrica e número de sementes por fruto. Na caracterização morfológica, as sementes foram imersas em água destilada para possibilitar os cortes, sendo as estruturas observadas em microscópio estereoscópio. No estudo pós-seminal, foram observados diariamente os processos de crescimento das plântulas em substrato rolo de papel-filtro e temperatura constante de 30 °C. Para avaliação do comportamento germinativo foram testadas as temperatura constantes de 15 °C, 25 °C, 30 °C, 40 °C e alternada de 20-30 °C, em substratos papel e areia, e foi avaliada a porcentagem, índice de velocidade de germinação e distribuição da frequência relativa, sendo os ensaios conduzidos em delineamento inteiramente casualizado, em esquema fatorial 5 x 2 (temperatura x substrato) com quatro repetições de 25 sementes, sendo as médias comparadas pelo teste Duncan a 5 % de probabilidade de erro. Os frutos de angico-preto apresentam grande variação no número de sementes por fruto. O eixo embrionário ocupa parte da região central da semente com posição axial e linear. A germinação é do tipo epígea e as plântulas são fanerocotiledonares. A temperatura constante de 30 °C e o substrato papel-filtro proporcionaram maiores médias de porcentagem e velocidade de germinação.Universidade Federal de Santa Maria2012-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/663010.5902/198050986630Ciência Florestal; Vol. 22 No. 3 (2012); 643-653Ciência Florestal; v. 22 n. 3 (2012); 643-6531980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/6630/4031Oliveira, Silvia Sanielle Costa deNeto, João Correia de AraújoCruz, Sihélio Júlio SilvaFerreira, Vilma Marquesinfo:eu-repo/semantics/openAccess2017-04-20T13:47:54Zoai:ojs.pkp.sfu.ca:article/6630Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-04-20T13:47:54Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
