Resumo: | The sudden death syndrome (SDS), caused by species of Fusarium, is a disease difficult to control and there are no management techniques and resistant cultivars that give long-term positive results. This study aimed to assess populations of Fusarium spp. and Trichoderma spp. associated to eight soybean genotypes, cultivated under no tillage; to determine if the control of Fusarium varies among isolates of Trichoderma; to identify isolates of Fusarium spp. obtained from different genotypes, and to determine their toxicity and pathogenicity to two genotypes of soybean. Soil and roots were collected from experimental plots located at the Fundação Centro de Experimentação e Pesquisa (FUNDACEP), obtaining isolates of Fusarium spp. and Trichoderma spp. There were no differences in the population of Fusarium spp. in plants with symptoms of SDS among the different genotypes. For Trichoderma spp. there was a significant difference among genotypes from plants with and without symptoms of SDS and the genotype CEPS 06006 RR had the biggest population of the antagonist. In the direct confrontation test, eight isolates of Trichoderma spp. obtained the highest score (1) in relation to the control of Fusarium spp. and isolates of Trichoderma spp. from soil of areas with the SDS symptom were more aggressive. Nine species of Fusarium: F. avenaceum, F. solani, F. equiseti, F. Acuminatum, F. kyushuense, F. graminum, F. subglutinans, F. verticillioides and F. lateritium were identified. All isolates promoted internerval chlorosis, necrosis and death of seedlings in the toxicity test. In the pathogenicity test in plants inoculated with the pathogen there was an increase in leaves and roots dry weight and in the number of pods, indicating that there may be species specificity of the species studied in relation to genotype. |

Assim, este trabalho objetivou quantificar populações de Fusarium spp. e Trichoderma spp. associadas à oito genótipos de soja, cultivados em sistema plantio direto, observar se o biocontrole de Fusarium spp. difere entre isolados de Trichoderma spp., identificar isolados de Fusarium spp. obtidos de diferentes genótipos e verificar sua toxicidade e patogenicidade a dois genótipos de soja. Amostras de solo e raízes foram coletadas em parcelas experimentais na Fundação Centro de Experimentação e Pesquisa (FUNDACEP), obtendo-se isolados de Fusarium spp. e Trichoderma spp. Não houve diferença na população de Fusarium spp. em plantas com sintomas de PVR entre os diferentes genótipos. Para Trichoderma spp., houve diferença entre as populações nos genótipos de plantas com e sem sintomas de PVR, tendo o genótipo CEPS 06006 RR apresentado maior população do antagonista. No teste de confronto direto, oito isolados de Trichoderma spp. obtiveram a melhor nota (um), em relação a Fusarium spp. e isolados de Trichoderma spp. oriundos de solo em áreas com o sintoma de PVR foram mais eficientes. Foram identificadas nove espécies de Fusarium: F. avenaceum, F. solani, F. equiseti, F. acuminatum, F. kyushuense, F. graminum, F. subglutinans, F. verticillioides e F. lateritium. Todos os isolados de Fusarium spp. provocaram clorose internerval, necrose e morte de plântulas no teste de toxicidade. No teste de patogenicidade, em plantas inoculadas com o patógeno houve aumento na massa seca de parte aérea e de raízes, no número de vagens, indicando que pode haver especificidade das espécies estudadas em relação ao genótipo.Coordenação de Aperfeiçoamento de Pessoal de Nível Superiorapplication/pdfporUniversidade Federal de Santa MariaPrograma de Pós-Graduação em AgronomiaUFSMBRAgronomiaPodridão vermelha da raizTrichodermaBiocontroleMetabólitos tóxicosSudden death syndromeTrichodermaBiocontrolToxic metabolitesCNPQ::CIENCIAS AGRARIAS::AGRONOMIACaracterização, toxicidade e patogenicidade de Fusarium spp. em genótipos de soja em sistema plantio diretoCharacterization, toxicity and pathogenicity of Fusarium spp. in soybean genotypes under no tillageinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/masterThesisBlume, Elenahttp://lattes.cnpq.br/3299996746493028Muniz, Marlove Fátima Briãohttp://lattes.cnpq.br/3148312031889388Deuner, Carolina Cardosohttp://lattes.cnpq.br/3029556593136573http://lattes.cnpq.br/5448205426679668Milanesi, Paola Mendes500100000009400500500500500dd9a87c1-c361-458f-b4bd-b78407907de83cb01915-8b9d-4609-a2f3-5b93dd5540d125b7c86e-9d34-4587-b91f-5a6b2c443843b6e04b42-1ba4-403a-b666-cb4be64bd72cinfo:eu-repo/semantics/openAccessreponame:Biblioteca Digital de Teses e Dissertações do UFSMinstname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMORIGINALMILANESI, PAOLA MENDES.pdfapplication/pdf4559806http://repositorio.ufsm.br/bitstream/1/5000/1/MILANESI%2c%20PAOLA%20MENDES.pdf789c3b454841733c1848570d1b51fd06MD51TEXTMILANESI, PAOLA MENDES.pdf.txtMILANESI, PAOLA MENDES.pdf.txtExtracted texttext/plain153083http://repositorio.ufsm.br/bitstream/1/5000/2/MILANESI%2c%20PAOLA%20MENDES.pdf.txt2fd6a273933d3bd375fd812ddd1250caMD52THUMBNAILMILANESI, PAOLA MENDES.pdf.jpgMILANESI, PAOLA MENDES.pdf.jpgIM Thumbnailimage/jpeg4902http://repositorio.ufsm.br/bitstream/1/5000/3/MILANESI%2c%20PAOLA%20MENDES.pdf.jpg2f168a8673c2d0804f422e18656d1805MD531/50002022-03-15 15:42:27.759oai:repositorio.ufsm.br:1/5000Biblioteca Digital de Teses e Dissertaçõeshttps://repositorio.ufsm.br/ONGhttps://repositorio.ufsm.br/oai/requestatendimento.sib@ufsm.br||tedebc@gmail.comopendoar:2022-03-15T18:42:27Biblioteca Digital de Teses e Dissertações do UFSM - Universidade Federal de Santa Maria (UFSM)false |

The sudden death syndrome (SDS), caused by species of Fusarium, is a disease difficult to control and there are no management techniques and resistant cultivars that give long-term positive results. This study aimed to assess populations of Fusarium spp. and Trichoderma spp. associated to eight soybean genotypes, cultivated under no tillage; to determine if the control of Fusarium varies among isolates of Trichoderma; to identify isolates of Fusarium spp. obtained from different genotypes, and to determine their toxicity and pathogenicity to two genotypes of soybean. Soil and roots were collected from experimental plots located at the Fundação Centro de Experimentação e Pesquisa (FUNDACEP), obtaining isolates of Fusarium spp. and Trichoderma spp. There were no differences in the population of Fusarium spp. in plants with symptoms of SDS among the different genotypes. For Trichoderma spp. there was a significant difference among genotypes from plants with and without symptoms of SDS and the genotype CEPS 06006 RR had the biggest population of the antagonist. In the direct confrontation test, eight isolates of Trichoderma spp. obtained the highest score (1) in relation to the control of Fusarium spp. and isolates of Trichoderma spp. from soil of areas with the SDS symptom were more aggressive. Nine species of Fusarium: F. avenaceum, F. solani, F. equiseti, F. Acuminatum, F. kyushuense, F. graminum, F. subglutinans, F. verticillioides and F. lateritium were identified. All isolates promoted internerval chlorosis, necrosis and death of seedlings in the toxicity test. In the pathogenicity test in plants inoculated with the pathogen there was an increase in leaves and roots dry weight and in the number of pods, indicating that there may be species specificity of the species studied in relation to genotype. |
