Resumo: | Temperature, culture medium, incubation period and pH for yellow passion fruit (Passiflora edulis f. flavicarpa) pollen germination, as well the effect of agrotoxics were studied. Temperature of 28 ± 0.5°C, culture medium with 50 g/L of sacarose, 0.2 g/L of boric acid and 1.0 g/L of calcium nitrate showed better germination of P. edulis f. flavicarpa pollen. No effect of the incubation period (17 and 48 hours) was registered for pollen germination of this plant. Percentage of pollen germination of P. edulis f. flavicarpa was not affected by the acaricid Dicofol + Tetradifon and by the insecticides Cartap, Fenpropathrin, and Abamectin. There was a small reduction in pollen germination in the presence of insecticides Malathion, Fenthion, Thrichorfon, Vamidothion, Deltamethrin, Methyl Parathion and the spreader-sticker N-dodecil benzen sodium sulphate. Ethion and Lambdacyhalothrin had severe effect on pollen germination of this plant. |

A temperatura de 28 + 0,5oC e o meio com 50 g/L de sacarose; 0,2 g/L de ácido bórico e 1,0 g/L de nitrato de cálcio forneceram as melhores condições para germinação dos grãos de pólen do maracujazeiro. Não detectou-se efeito significativo do tempo de incubação (17 e 48 horas) na germinação dos grãos de pólen. A percentagem de germinação dos grãos de pólen não foi prejudicada pelo acaricida Dicofol + Tetradifon e pelos inseticidas Cartap, Fenpropathrin e Abamectin. Os demais agrotóxicos afetaram a germinação dos grãos de pólen. Os inseticidas Malathion, Fenthion, Trichlorfon, Vamidothion, Deltamethrine, Parathion Methyl e o espalhante adesivo N-dodecil benzeno de sulfato de sódio reduziram moderadamente a germinação, enquanto o Ethion e o Lambdacyhalothrin interferiram severamente na germinação dos grãos de pólen.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária Brasileirada Silva, Mairon MouraBruckner, Claudio HorstPicanço, MarceloCruz, Cosme Damião1999-03-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/5190Pesquisa Agropecuaria Brasileira; v.34, n.3, mar. 1999; 347-352Pesquisa Agropecuária Brasileira; v.34, n.3, mar. 1999; 347-3521678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/5190/2382info:eu-repo/semantics/openAccess2010-07-07T12:57:17Zoai:ojs.seer.sct.embrapa.br:article/5190Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-07-07T12:57:17Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
