Resumo: | The objective of this work was to evaluate the effect of liming, harvest period and drying method on the sanitary quality of peanut (Arachis hypogaea L.) cv. Botutatu, cultivated in the field in the dry season. The experimental design was a split split plot replicated four times in completely randomized blocks. Lime levels (0.0 and 1.8 ton/ha) were applied in the plots, four different harvesting periods starting at 104 days after planting were assigned to the split plots and two conditions of drying (forced air oven at 30oC and ambient at 24oC and 60% of relative humidity) were attributed to the split split plots. Populations of soil fungus and fungus associated to the seeds and to the pods and aflatoxin production potential were evaluated at each harvest. There was no effect of liming on the Aspergillus spp. population in soil as well as on the pods and seeds. The delay at the time of harvest provides contamination increase of Aspergillus flavus in the pods and in G1 and G2 aflatoxin production; the drying conditions in ambient propitiate larger incidence for Rhizopus spp. in the pods and smaller incidence for Aspergillus flavus in the seeds. |

O delineamento experimental foi o de blocos ao acaso em parcela subsubdividida, com quatro repetições. As parcelas foram constituídas por ausência e presença de calcário dolomítico (1,8 t/ha), as subparcelas, por quatro épocas de colheita, a partir de 104 dias após a semeadura, e as subsubparcelas, por duas condições de secagem (estufa a 30oC e ambiente a 24oC e 60% de umidade relativa do ar). Em cada colheita, foi realizada a avaliação da população de fungos no solo, nas sementes e nas vagens, assim como do potencial de produção de aflatoxina destes isolados. A calagem não interfere na população de Aspergillus spp. no solo e não previne sua contaminação nas vagens e nas sementes do amendoim; o atraso na época de colheita proporciona aumento da contaminação de Aspergillus flavus nas vagens e da produção de aflatoxina G1 e G2; as condições de secagem em ambiente propiciam maior incidência por Rhizopus spp. nas vagens e menor incidência por Aspergillus flavus nas sementes.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRossetto, Claudia Antonia VieiraLima, Tatiana de MoraesViegas, Élson de CarvalhoSilva, Otniel FreitasBittencourt, Anna Maria2003-05-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/6609Pesquisa Agropecuaria Brasileira; v.38, n.5, maio 2003; 567-573Pesquisa Agropecuária Brasileira; v.38, n.5, maio 2003; 567-5731678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/6609/3666info:eu-repo/semantics/openAccess2014-08-11T19:01:34Zoai:ojs.seer.sct.embrapa.br:article/6609Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-08-11T19:01:34Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false |
