Resumo: The paper objective was to describe and to illustrate the external and internal morphologic aspects of the seed, the germination process external aspects and seedlings phases of jacarandá- da- bahia (Dalbergia nigra VELLOZO) Fr. All. Ex. Bentham Leguminoseae- Papilionoidae). It was found that seed have tegument of bright medium brown color, with kidney shape and symmetricaless form of 7,0 mm to 10,0 mm of length for 5,9 mm to 8,8 mm of width; germination epigeous phanerocotylar, free of tegument, and occur at 30 days after sowing. Seedlings with opposing follicles, of herbaceous consistency and green clear color, with about 1,2 cm of length for 0,8 cm of width. Observations on the seeds internal and external morphology, allied to the ones made on the seedlings phases of development, allow identification of this species in the initial growth and the overall research results may be used for other taxonomic, silvicultural and ecological purposes.

All. Ex. Bentham Leguminoseae Papilionoidae). Verificou-se que a semente possui tegumento de cor pardo brilhante, com forma assimétrica reniforme e tamanho de 7,0 mm a 10,0 mm de comprimento por 5,9 mm a 8,8 mm de largura. A germinação é fanerocotiledonar, epígea, livres dos tegumentos e ocorre aos 30 dias após a semeadura. As plântulas possuem com folíolos opostos, de consistência herbácea e de cor verde- lara, com cerca de 1,2 cm de comprimento por 0,8 cm de largura. As observações da morfologia interna e externa das sementes, aliadas às das várias fases do desenvolvimento das plântulas e mudas, permitem a identificação desta espécie na fase inicial de crescimento e os resultados obtidos poderão ser empregados em estudos taxonômicos, silviculturais e ecológicos.  Embrapa Florestas2011-03-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/219Pesquisa Florestal Brasileira; n. 52 (2006): jan./jun.; 141Pesquisa Florestal Brasileira; No. 52 (2006): jan./jun.; 1411983-26051809-3647reponame:Pesquisa Florestal Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://pfb.cnpf.embrapa.br/pfb/index.php/pfb/article/view/219/170Rego, Gizelda MaiaPossamai, Edilbertoinfo:eu-repo/semantics/openAccess2021-03-19T21:48:10Zoai:pfb.cnpf.embrapa.br/pfb:article/219Revistahttps://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:2021-03-19T21:48:10Pesquisa Florestal Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
