Resumo: | The recovery of degraded areas led to an increase of native forest seedlings production. Jatoba-do-cerrado (Hymenaea stignocarpa Mart.) and jatoba-da-mata (Hymenaea courbaril L.), native species of the Brazilian Cerrado, are widely used for the recovery of this biome. Although forest species present a diversity of pathogens disseminated by seeds, few studies have been published and no study was found for jatoba. Because the seed is one of the main forms of pathogen dissemination, the aim of our work was to evaluate the natural incidence of fungi in seed lots of jatoba-do-cerrado and jatoba-da-mata and the performance of different fungicides for seed treatment recommendation. The experiment was carried out at the Genetics and Biotechnology Laboratory of the University Center of Patos de Minas. Two chemical treatments were submitted in the seeds and then divided into seven replicates of 15 seeds for each species. The first treatment was with the active principle thiophanate-methyl and fluazine, commercial name Certeza®, in the dose of 145 mL of the product in 100 kg of seeds. The second treatment was with fludioxonil, commercial name Maxim® XL, in the dose of 100 mL of the product in 100 kg of seeds. There was a third treatment corresponded to the control (without seed treatment). The visual analyzes were performed after eight days on each seed with a magnifier to verify the presence of developing fungal colonies. The growth fungi fructifications were observed using a stereomicroscope. The found fungi species were: Aspergillus sp., Fusarium sp., Mucor sp., Penicillium sp., Pestalotiopsis sp., Phomopsis sp., Rhizoctonia sp., Rhizopus sp. and Trichoderma sp. It occurred interaction between seed treatment and species for Aspergillus sp., Fusarium sp., Mucor sp., Phomopsis sp., Rhizoctonia sp. and Trichoderma sp. For Penicillium sp., Pestalotiopsis sp. and Rhizopus sp., only the isolated factors were significant. Jatoba-do-cerrado seeds had a higher incidence than jatoba-da-mata seeds in all the found fungi. Certeza® and Maxim® XL have potential in seed treatment for the species. The fungicide Certeza® was more efficient to control the pathogenic fungi in seed treatment. |

Jatobá-do-cerrado (Hymenaea stignocarpa Mart.) e jatobá-da-mata (Hymenaea courbaril L.), espécies nativas do Cerrado brasileiro, são amplamente utilizadas na recuperação deste bioma. Apesar da diversidade de fungos encontrada em sementes de espécies florestais, poucos são os estudos publicados, e não nenhum relato para o jatobá. Por a semente ser um dos principais meios de disseminação de patógenos, o objetivo do trabalho foi avaliar a incidência natural de fungos em lotes de semente de jatobá-do-cerrado e jatobá-da-mata, e a performance de diferentes fungicidas para a recomendação do tratamento de sementes. O experimento foi realizado no Laboratório de Genética e Biotecnologia do Centro Universitário de Patos de Minas. Dois tratamentos químicos foram realizados nas sementes, que então foram divididas em sete repetições com 15 sementes cada. O primeiro tratamento foi realizado com o princípio ativo tiofanato-metílico e fluazinam, nome comercial Certeza®, na dose de 145 mL do produto para 100 kg de sementes. O segundo tratamento foi realizado com fludioxonil, nome comercial Maxim® XL, na dose de 100 mL do produto para 100 kg de sementes. O terceiro tratamento correspondeu a testemunha (sem tratamento de sementes). Após oito dias, a análise visual foi realizada com o auxílio de uma lupa para verificar a presença de colônias de fungos. As frutificações dos fungos foram observadas com o auxílio de um microscópio óptico. Após as avaliações, os seguintes fungos foram encontrados: Aspergillus sp., Fusarium sp., Mucor sp., Penicillium sp., Pestalotiopsis sp., Phomopsis sp., Rhizoctonia sp., Rhizopus sp. e Trichoderma sp. Ocorreu interação entre o tratamento de sementes e as espécies para Aspergillus sp., Fusarium sp., Mucor sp., Phomopsis sp., Rhizoctonia sp. e Trichoderma sp. Para Penicillium sp., Pestalotiopsis sp. e Rhizopus sp., apenas os fatores isolados foram significativos. Sementes de jatobá-do-cerrado possuíram maior incidência do que as sementes de jatobá-damata para todos os fungos encontrados. Certeza® e Maxim® XL possuem potencial para o tratamento de sementes de jatobá. O fungicida Certeza® foi mais eficiente para o controle de fungos patogênicos no tratamento de sementes.EDUFU2018-08-08info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.ufu.br/index.php/biosciencejournal/article/view/4186610.14393/BJ-v34n1a2018-41866Bioscience Journal ; Vol. 34 No. 4 (2018): July/Aug.; 868-874Bioscience Journal ; v. 34 n. 4 (2018): July/Aug.; 868-8741981-3163reponame:Bioscience journal (Online)instname:Universidade Federal de Uberlândia (UFU)instacron:UFUenghttps://seer.ufu.br/index.php/biosciencejournal/article/view/41866/22645Copyright (c) 2018 Nayara Cecília Rodrigues Costa, Fábio Janoni Carvalho, Fernando Cezar Juliatti, Mariana Viana Castro, Walter Vieira da Cunhahttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessCosta, Nayara Cecília RodriguesCarvalho, Fábio JanoniJuliatti, Fernando CezarCastro, Mariana Vianada Cunha, Walter Vieira2022-02-14T03:33:34Zoai:ojs.www.seer.ufu.br:article/41866Revistahttps://seer.ufu.br/index.php/biosciencejournalPUBhttps://seer.ufu.br/index.php/biosciencejournal/oaibiosciencej@ufu.br||1981-31631516-3725opendoar:2022-02-14T03:33:34Bioscience journal (Online) - Universidade Federal de Uberlândia (UFU)false |
