Resumo: Seeds of weeds occurring in a cotton culture in Campinas, SP, Brazil, were collected. The sensitivity to light of seeds of 43 species belonging to 13 families was studied: 19 species were positive photoblastic, 6 species did not show photoblastism, 17 species could not have their photoblastic behaviour determined due mainly to low germination, and one species presented variable results. The possible reasons for the variation observed in the photoblastic behaviour of the weed seeds are discussed, as well as their ecological implications.

Foi estudada a sensibilidade à luz, para a germinação, de 43 espécies, pertencentes a 13 famílias: 19 espécies apre­sentaram fotoblastismo positivo, 6 não apresentaram fotoblastismo, 17 não tiveram seu com­portamento fotoblástico determinado, em virtude, principalmente, da baixa germinação, e uma espécie apresentou resultados variáveis. São discutidas as possíveis razões da variação encontrada no comportamento fotoblástico das invasoras, bem como suas implicações ecoló­gicas.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraKlein, Aldo LuizFelippe, Gil Martins1991-07-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/3428Pesquisa Agropecuaria Brasileira; v.26, n.7, jul. 1991; 955-966Pesquisa Agropecuária Brasileira; v.26, n.7, jul. 1991; 955-9661678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/3428/761info:eu-repo/semantics/openAccess2009-12-15T14:04:49Zoai:ojs.seer.sct.embrapa.br:article/3428Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2009-12-15T14:04:49Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
