Resumo: | The occurrence of pathogenic fungi in wheat seeds has been frequently reported, and this association is sometimes responsible for decreasing seeds physiologic quality, as well as introducing and disseminating pathogens and transferring early pathogens to the progeny. The objective of this study was to perform the first survey of fungi associated with upland and irrigated wheat seeds, in the Mato Grosso State, Brazil. The Brilhante, BRS 264, Aliança, BR 18, BRS 254, and IAC 350 cultivars were used. The health analysis was performed with the aid of the Blotter test adapted to water restriction (NaCl - 1.0 MPa), with eight replications (25 seeds per plate), totalizing 200 seeds per sample. The fungi identification was based on their morphologic features and their incidence was quantified. The results showed variability in diversity and incidence, with a total of 20 fungi genera in the 32 samples. Cladosporium cladosporioides and Bipolaris sorokiniana were present in 96.87% of the samples, followed by Fusarium graminearum, with 75.00%, and Pyricularia grisea, with 59.37%. |

Assim, objetivou-se, neste trabalho, efetuar o primeiro levantamento de fungos associados a sementes de trigo irrigado e sob sistema de sequeiro, em Mato Grosso. As cultivares utilizadas foram Brilhante, BRS 264, Aliança, BR 18, BRS 254 e IAC 350. A avaliação da sanidade foi feita pelo método de incubação em papel filtro (Blotter test), modificado com restrição hídrica (NaCl - 1,0 MPa), com oito repetições (25 sementes por placa), totalizando 200 sementes por amostra. A identificação dos fungos foi feita com base em suas características morfológicas, e suas incidências foram quantificadas. Os resultados apresentaram variações na diversidade e incidência, com a presença de 20 gêneros de fungos, nas 32 amostras analisadas. Os fungos Cladosporium cladosporioides e Bipolaris sorokiniana foram encontrados em 96,87% das amostras analisadas, Fusarium graminearum em 75,00% e Pyricularia grisea em 59,37%.Escola de Agronomia - Universidade Federal de Goiás2011-12-19info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPesquisa experimentalapplication/savehttps://revistas.ufg.br/pat/article/view/12388Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 41, n. 4, Oct./Dec. 2011; 572-578Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 41, n. 4, out./dez. 2011; 572-578Pesquisa Agropecuária Tropical; v. 41, n. 4, out./dez. 2011; 572-5781983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGporhttps://revistas.ufg.br/pat/article/view/12388/10020Copyright (c) 2020 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessKobayasti, LeimiPires, Aline Pellozo2020-07-09T19:35:28Zoai:ojs.revistas.ufg.br:article/12388Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:55:50.801808Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
