Resumo: This study investigated the effect of seed size and shading on the production of seedlings of Muirapiranga (Eperua bijuga Mart. Ex Benth.). Three size classes were tested: large (more than 95 g), average (75 g to 95 g) and small (less than 75 g). The two shading intensities (30% and 50%) were obtained by using black plastic screening. Seeds were also sown under full open sky (at 0% shading intensity). Neither seed size nor shading showed any influence on the germination of seeds or on the production of seedlings. Larger seeds grew into seedlings of greater height, diameter and dry weight both above and below ground. These parameters were not influenced by different shade levels.

Foram testadas três classes de tamanho de sementes, baseadas no peso, em: grandes (acima de 95 g), médias (75 g - 95 g) e pequenas (abaixo de 75 g). Os níveis de sombreamento (30% e 50%) foram obtidos através de telas de poliolefinas de cor preta; o nível de 0% foi obtido por semeadura ao céu aberto. Os tamanhos de semente e os níveis de sombreamento não exerceram influência nem na germinação de sementes nem na produção de mudas. As sementes grandes proporcionaram mudas com maior altura, diâmetro do colo e matéria seca da parte aérea e do sistema radicular. Esses parâmetros não foram influenciados pelos níveis de sombreamento.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraFaçanha, José Gilberto VieiraVarela, Vania Palmeira2014-04-17info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/14674Pesquisa Agropecuaria Brasileira; v.22, n.11/12, nov./dez. 1987; 1185-1188Pesquisa Agropecuária Brasileira; v.22, n.11/12, nov./dez. 1987; 1185-11881678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/14674/8357info:eu-repo/semantics/openAccess2014-10-14T19:35:55Zoai:ojs.seer.sct.embrapa.br:article/14674Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-10-14T19:35:55Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
