Resumo: | This study aimed to verify the transmission of fungi through seeds of Schinus terebinthifolius Raddi. (aroeira-vermelha) collected in the municipality of Santa Maria-RS, as well as the pathogenicity of the fungus Pestalotiopsis sp. Isolated from these seeds, aroeira-vermelha seedlings. For the transmission test 100 seeds were used, divided into four replicates of 25 each. The seeds were sown in sand and the evaluations were weekly, quantified the number of seedlings emerging and symptomatic. The fungus Pestalotiopsis sp. identified in a high percentage in both the sanity test (55%) and in the transmission test (52%) was isolated in culture medium for subsequent verification of pathogenicity. Inoculation of Pestalotiopsi sp. in seedlings of aroeira-vermelha spraying was carried out via the concentration of 2.106 conidia/mL, the evaluations were weekly for 28 days. The fungi identified in the test transmission were: Pestalotiopsis sp. (52%), Fusarium sp. (15%) and Cladosporium sp. (12%). The fungus Pestalotiopsis sp. presented the seedlings of aroeira-vermelha pathogenic, causing leaf spots that coalesced with thepassage of time, and lead to the fall of leaves. |

(aroeira-vermelha) coletadas no município de Santa Maria – RS, assim como, a patogenicidade do fungo Pestalotiopsis sp. isolado a partir dessas sementes, em mudas de aroeira-vermelha. Para o teste de transmissão foram utilizadas 100 sementes, divididas em quatro repetições de 25 cada. A semeadura foi realizada em areia e as avaliações foram semanais, quantificou-se o número de plântulas emergentes e sintomáticas. O fungo Pestalotiopsis sp. identificado em alto percentual, tanto no teste de sanidade (55%), quanto no teste de transmissão (52%), foi isolado em meio de cultura, para posterior verificação da patogenicidade. A inoculação de Pestalotiopsis sp. em mudas de aroeira-vermelha foi realizada via aspersão na concentração de 2.106 conídios/mL, as avaliações foram semanais durante 28 dias. Os fungos identificados no teste de transmissão foram: Pestalotiopsis sp. (52%), Fusarium sp. (15%) e Cladosporium sp. (12%). O fungo Pestalotiopsis sp. apresentou-se patogênico as mudas de aroeira-vermelha, causando manchas foliares, que coalesceram com o passar da tempo e levaram a queda da folhas.UEL2012-12-20info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/886310.5433/1679-0359.2012v33n6Supl1p2767Semina: Ciências Agrárias; Vol. 33 No. 6Supl1 (2012); 2767-2774Semina: Ciências Agrárias; v. 33 n. 6Supl1 (2012); 2767-27741679-03591676-546Xreponame:Semina.
