Resumo: | The objective of this work was to evaluate the effectiveness of thermotherapy in the control of fungi associated with seeds of cumaru (Amburana cearensis A.C. Smith) from two localities, after thermal and chemical treatment. The health assessment was conducted by the method of incubation on paper filter (Blotter Test) and physiological quality seeds was determined by germination tests and electrical conductivity. The thermal treatment was used by immersion in water heated to 60 degrees for 5, 10 and 20 minutes. The chemical treatment was done with Captan fungicide. The study used 100 seeds per treatment (10 seeds per petri dish), which were incubated for seven days, at a temperature of 22 ± 2°C and 12-hour photoperiod. The qualitative and quantitative assessment (expressed in percentage) of the fungi associated with the seeds was done with the help of a stereoscope. In the examined samples, only the Aspergillus niger fungus was found. There was a higher incidence of A. niger in the lot from the town of Catolé Rocha, Paraíba State, with very low incidence of the fungus in the town Petrolina, Pernambuco State. The treatments with the best results were fungicide and thermotherapy for 20 minutes. |

Smith) de duas localidades, após tratamento térmico e químico. A avaliação da sanidade foi realizada pelo método de incubação em papel filtro (Blotter Test) e a qualidade fisiológica das sementes pelos testes de germinação e condutividade elétrica. O tratamento térmico utilizado foi por imersão em água aquecida a 60°C por 0, 5, 10 e 20 min. e o tratamento químico foi feito com o fungicida Captan. Utilizaram-se 100 sementes por tratamento (dez sementes por placa de Petri), as quais foram incubadas, por sete dias, à temperatura de 22 ± 2°C e fotoperíodo de 12h. A avaliação qualitativa e quantitativa (expressa em porcentagem) dos fungos associados às sementes foi realizada com auxílio de microscópio estereoscópico. Nas amostras examinadas, constatou-se apenas a incidência do fungo Aspergillus Níger. Houve maior incidência de A. Níger no lote da localidade Catolé do Rocha, Estado da Paraíba, sendo a incidência do fungo muito baixa na localidade Petrolina, Estado do Pernambuco. Os tratamentos que apresentaram melhor resultado foram o fungicida e a termoterapia por 20 min.Universidade Estadual de Maringá2011-02-16info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciAgron/article/view/564510.4025/actasciagron.v33i1.5645Acta Scientiarum.
