Resumo: A study of pollen viability was carried out aiming to obtain the best medium concentration for pollen germination. Different concentrations of sucrose, glucose, galactose, lactose and mannitol in distilled water with and without boric acid were tested as media for germination of pollen of Hevea camargoana in the laboratory. Twenty percent sucrose with 0.01% boric acid at 25 to 30°C gave the best results. Tube lengths of 74.78 μm were obtained. Pollen tubes emerged within 30 minutes and completed full growth within six hours. Adding 0.01% boric acid increased the percentage germination markedly in all media except in mannitol.

Foram utilizadas diferentes concentrações de sacarose, glicose, galactose, lactose e manitol diluídos em água destilada, com e sem ácido bórico, como ambientes para germinação do pólen. Foi observado que sacarose a 20% com 0,01% de ácido bórico na amplitude de 25 a 30°C de temperatura apresentou o melhor resultado. Foram obtidos tubos polínicos de 74,78 μm. Os tubos polínicos emergiram dentro de 30 minutos, e após seis horas já se encontravam completamente desenvolvidos. A adição de 0,01% de ácido bórico contribuiu marcadamente para o aumento da germinação, em todos os meios, exceto em manitol.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraGonçalves, Paulo de SouzaPaiva, João Rodrigues deRebello, Antonio P.2014-04-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/15626Pesquisa Agropecuaria Brasileira; v.17, n.2, fev. 1982; 287-291Pesquisa Agropecuária Brasileira; v.17, n.2, fev. 1982; 287-2911678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAenghttps://seer.sct.embrapa.br/index.php/pab/article/view/15626/9628info:eu-repo/semantics/openAccess2014-04-16T12:24:17Zoai:ojs.seer.sct.embrapa.br:article/15626Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-04-16T12:24:17Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
