Resumo: Mycosphaerella leaf disease (MLD) is one of the most important diseases of eucalypts plantations worldwide. However, only recently it has become relevant in Portugal. Caused by a complex of Mycosphaerella species, this disease reduces the photosynthetic area and can cause tree defoliation. In extreme cases it causes reduction in the volume of wood produced. In order to relate the observed symptoms of MLD with the presence of the pathogen and at the same time obtaining an evaluation of eucalypt clones and family susceptibility, two experimental plantations were established in places where the disease has been detected. Data on the percentage of affected crown (necrosis or defoliation) were collected and some of the Mycosphaerella species present were identified (M. africana, M. communis, M. grandis, M. lateralis, M. marksii, M. nubilosa, M. parva, M. vespa and M. walkeri).

Esta doença, causada por um complexo de espécies de Mycosphaerella, reduz a área fotossintética da árvore, podendo causar desfolha, com consequente redução da taxa de crescimento e do volume de madeira produzido. Com o objectivo de relacionar os sintomas observados com a presença do agente patogénico e avaliar a susceptibilidade de clones e famílias de eucalipto, foram estabelecidas duas plantações experimentais em locais onde foi detectada a doença. Foram recolhidos dados relativos à percentagem de área da copa afectada (por necroses ou desfolha) e identificadas as espécies de Mycosphaerella associadas (M. africana, M. communis, M. grandis, M. lateralis, M. marksii, M. nubilosa, M. parva, M. vespa e M. walkeri).Sociedade de Ciências Agrárias de Portugal2018-11-18T00:00:00Zinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://doi.org/10.19084/rca.15610eng2183-041X0871-018XSilva, MárciaValente, CarlosNeves, LucindaMachado, Helenainfo:eu-repo/semantics/openAccessreponame:Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos)instname:Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãoinstacron:RCAAP2022-09-06T09:23:46Zoai:ojs.revistas.rcaap.pt:article/15610Portal AgregadorONGhttps://www.rcaap.pt/oai/openaireopendoar:71602024-03-19T15:30:32.806431Repositório Científico de Acesso Aberto de Portugal (Repositórios Cientìficos) - Agência para a Sociedade do Conhecimento (UMIC) - FCT - Sociedade da Informaçãofalse
