Resumo: | Anthracnose, generally caused by Colletotrichum gloeosporioides, affects inflorescences quality in different species of ornamental tropical plants and it is one of the main fungal diseases to those crops. The objective of this study was to evaluate the aggressiveness and exoenzimes production on solid medium of 25 Colletotrichum isolates collected from anthurium, torch ginger, and heliconia plants with necrosis symptoms. The symptomatic floral stems were harvested in different counties of the Pernambuco State, Brazil, and carried to the laboratory, where the isolation process took place. The isolates were inoculated in the floral stems bracts of the three species studied, and the aggressiveness evaluated five days after inoculation. Isolates were also plated on specific culture media to determine amylolytic, lipolytic, and proteolytic activity, and assessed seven days after inoculation. The isolates aggressiveness was variable and some of them were not pathogenic when inoculated to their origin hosts. Six isolates were pathogenic to all the analyzed ornamental species and four isolates showed host specificity. All tested isolates presented amylolytic, lipolytic, and proteolytic activity. No relation between aggressiveness and enzyme activity was observed in the isolates tested.KEY-WORDS: Anthurium andraeanum; Etlingera elatior; Heliconia spp.; variability. |

O objetivo deste trabalho foi verificar a agressividade e a produção de exoenzimas, em meio sólido, de 25 isolados de Colletotrichum obtidos a partir de inflorescências de antúrio, bastão do imperador e helicônia, com sintomas de necrose. As hastes florais sintomáticas foram colhidas em diversos municípios produtores do Estado de Pernambuco e, em seguida, levadas para o laboratório, onde foram realizados os isolamentos. Os isolados foram inoculados em hastes florais das três culturas avaliadas e a agressividade foi avaliada cinco dias após a inoculação. Os isolados também foram plaqueados, em meios de cultura específicos, para verificar a atividade amilolítica, lipolítica e proteolítica, sendo avaliados aos sete dias após a inoculação. A agressividade dos isolados foi variável e alguns isolados não foram patogênicos, quando inoculados em seus hospedeiros de origem. Seis isolados foram patogênicos a todas as espécies ornamentais avaliadas e quatro isolados apresentaram especificidade ao hospedeiro. Todos os isolados avaliados apresentaram atividade amilolítica, lipolítica e proteolítica. Não foi observada relação entre a agressividade e as atividades enzimáticas nos isolados testados.
