Resumo: The objective of this work was to investigate the effect of substrate, color and size on the germination and vigor of Melanoxylon brauna seeds. It was performed two essays. In the first, the seeds were classified by color (light and dark) and size (small and large). In the second essay, it was investigated the influence of substrates on sand, between sand, above paper, between paper and in paper rolls, type germitest. In both essays, the seeds were maintained in controlled conditions (light and temperature) during 10 days. The percentage of germination and germination speed index (GSI) were calculated. Furthermore, it was determined the weight of 1,000 seeds and the germination of the species was characterized by observation until the seedling formation. The weight of 1,000 seeds of M. brauna was 133.43 g, in average. The root protrusion occurred around 72 hours after the beginning of imbibition, and the germination was as epigel phanerocotyledonar. Small and light color seeds presented percentage of germination and GSI lower than others. The large seeds, independent of color, and small dark seeds presented the higher GSI and percentage of germination. Paper roll is the substrate indicated to conduct germination tests of Melanoxylon brauna.

Para tanto foram realizados dois ensaios. No primeiro, as sementes foram classificadas quanto à cor (claras e escuras) e ao tamanho (pequenas e grandes). No segundo ensaio foi investigada a influência dos substratos sobre areia, entre areia, sobre papel, entre papel e rolos de papel, tipo germitest. Em ambos os ensaios, as sementes foram mantidas em condições controladas (luz e temperatura) durante 10 dias. Foi calculado o percentual de germinação e o índice de velocidade de germinação (IVG). Além disso, foi determinado o peso de 1.000 sementes e a germinação da espécie foi caracterizada mediante acompanhamento visual até a formação da plântula. O peso de 1.000 sementes de M. brauna foi de 133,43 g, em média. A protrusão da raiz principal ocorreu em torno de 72 horas após início da embebição, e a germinação observada foi do tipo fanerocotiledonar epígea. Sementes pequenas e claras apresentaram germinação e IVG inferiores às demais. As sementes grandes, independentes da cor, e as pequenas escuras tiveram os maiores IVG e porcentagem de germinação. O substrato mais indicado para a realização de testes de germinação de Melanoxylon brauna foi o rolo de papel.Embrapa Florestas2014-07-07info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfapplication/ziphttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/55810.4336/2014.pfb.34.78.558Pesquisa Florestal Brasileira; v. 34 n. 78 (2014): abr./jun.; 141-147Pesquisa Florestal Brasileira; Vol. 34 No. 78 (2014): abr./jun.; 141-1471983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/558/363https://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/558/1150Flores, Andressa VasconcelosBorges, Eduardo Euclydes de Lima eGonçalves, José Francisco de CarvalhoGuimarães, Valéria MontezeAtaíde, Glauciana da MataBarros, Daniela de PáduaPereira, Márcio Diasinfo:eu-repo/semantics/openAccess2017-04-28T12:48:18Zoai:pfb.cnpf.embrapa.br/pfb:article/558Revistahttps://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:2017-04-28T12:48:18Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
