Resumo: | Anthracnose, a disease caused by fungi of the Colletotrichum genus, affects many crops, including ornamental plants. This study aimed at evaluating the pathogenicity and aggressiveness of the Colletotrichum gloeosporioides Penz. (Sacc.) isolates Cg1 (papaya), Cg2 (guava) and Cg3 (mango) in the ornamental pepper varieties Stromboli, Etna and Pirâmide, during two different periods (July/August and November/December 2013). The fungi pathogenicity and the severity of plant symptoms were assessed using a grading scale. The three C. gloeosporioides isolates were pathogenic to the three ornamental pepper varieties studied, exhibiting different levels of aggressiveness among them. The environmental conditions influenced the isolates aggressiveness, with the most severe symptoms observed in the second assessment period. |

Objetivou-se avaliar a patogenicidade e agressividade de isolados de Colletotrichum gloeosporioides Penz. (Sacc.) Cg1 (mamoeiro), Cg2 (goiabeira) e Cg3 (mangueira), nas variedades de pimentas ornamentais Stromboli, Etna e Pirâmide, em duas épocas do ano (julho/agosto e novembro/dezembro de 2013). Avaliou-se a patogenicidade dos fungos e a severidade dos sintomas nas plantas utilizando-se uma escala de notas. Os três isolados de C. gloeosporioides foram patogênicos às três variedades de pimenta ornamental avaliadas, apresentando níveis diferenciados de agressividade entre as variedades. Houve influência das condições ambientais na agressividade dos isolados, sendo que a maior severidade foi obtida na segunda época de condução do experimento.Escola de Agronomia - Universidade Federal de Goiás2016-10-04info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionAvaliado por paresapplication/pdfhttps://revistas.ufg.br/pat/article/view/41483Pesquisa Agropecuária Tropical [Agricultural Research in the Tropics]; v. 46, n. 3, Jul./Sep. 2016; 321-326Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics); v. 46, n. 3, jul./set. 2016; 321-326Pesquisa Agropecuária Tropical; v. 46, n. 3, jul./set. 2016; 321-3261983-4063reponame:Pesquisa Agropecuária Tropical (Online)instname:Universidade Federal de Goiás (UFG)instacron:UFGenghttps://revistas.ufg.br/pat/article/view/41483/21787Copyright (c) 2016 Pesquisa Agropecuária Tropical (Agricultural Research in the Tropics)info:eu-repo/semantics/openAccessAraújo, Neilton Antonio FiusaVieira, Joana D´arc MendesMoura, Marlene da RochaPessoa, Wagner Rogério Leocádio SoaresBarguil, Beatriz Meireles2020-07-13T18:09:37Zoai:ojs.revistas.ufg.br:article/41483Revistahttps://revistas.ufg.br/patPUBhttps://revistas.ufg.br/pat/oaiaseleguini.pat@gmail.com||mgoes@agro.ufg.br1983-40631517-6398opendoar:2024-05-21T19:56:13.756407Pesquisa Agropecuária Tropical (Online) - Universidade Federal de Goiás (UFG)true |
