The objective of this work was to determine the composition and evaluate in vitro and in vivo effects of essential oils (Lippia sidoides Cham., Ocimum gratissimum L., Cymbopogon citratus Stapf., Ocimum selloi Benth., Citrus sinensis L., Ocimum micranthum Willd., Ocimum sp., and Piper aduncum L.) on the control of Fusarium rot in melon fruits, caused by the fungus Fusarium pallidoroseum. The essential oils were obtained by hydrodistillation and their chemical composition was determined by GCMS and GC-FID. The effect of each essential oil (concentrations of 0, 500, 1500, and 3000μL L-1) on the fungal mycelial growth was evaluated in in vitro experiment. The effective concentration that inhibited 50% of mycelial growth (EC50) was determined through the probit method; mycelial growth index (MGI) was also calculated. The essential oils with higher potential for inhibiting mycelial growth of F. pallidoroseum were evaluated for their inhibitory effect on the fungus spore germination in in vitro and in vivo experiments using melon fruits (variety Galia). Chemical composition analysis of essential oils enabled the identification of varying amounts of chemical compounds, with predominance of monoterpenes. The essential oils of L. sidoides, O. gratissimum, C. citratus, and O. micranthum presented higher inhibiting effects on F. pallidoroseum mycelial growth and spore germination, therefore, they are promising raw materials for the development of commercial fungicides, mainly for controlling postharvest rot caused by F. pallidoroseum.
RESUMO - Objetivou-se com esse trabalho determinar a composição e avaliar, ‘in vitro’ e ‘in vivo’, o efeito dos óleos essenciais de alecrim-pimenta (Lippia sidoides Cham.), alfavacacravo (Ocimum gratissimum L.), capim-limão (Cymbopogon citratus Stapf.), elixir-paregórico (Ocimum selloi Benth.), laranja (Citrus sinensis L.), manjericão (Ocimum micranthum Willd.), Ocimum sp. e pimenta-de-macaco (Piper aduncum L.) no controle da podridão por Fusarium causada pelo fungo Fusarium pallidoroseum em frutos de melão. Os óleos essenciais foram obtidos por hidrodestilação e a composição química determinada por GC-MS e GC-FID. No ensaio ‘in vitro’, foi testado o efeito de cada óleo essencial (concentrações de 0, 500, 1500 e 3000μL/L) sobre o crescimento micelial do patógeno. Determinou-se a concentração efetiva que inibiu o crescimento micelial em 50% (EC50) pelo método de probit e o Índice de Crescimento Micelial (ICM). Os óleos essenciais com maior potencial inibidor no crescimento micelial do F. pallidoroseum foram avaliados quanto ao efeito inibitório na germinação de esporos do fungo no ensaio ‘in vitro’ e ‘in vivo’ com frutos de melão ‘Galia’. A análise da composição química possibilitou a identificação de quantidades variáveis de compostos químicos, com predominância dos compostos monoterpênicos. Os óleos essenciais de alecrimpimenta, alfavaca-cravo, capim-limão e manjericão, apresentaram melhores efeitos na inibição do crescimento micelial e germinação
dos esporos do fungo, mostrando-se promissores como matériaprima para o desenvolvimento de fungicidas comerciais, em especial no controle de podridão causada por F. pallidoroseum, em póscolheita.

Invasive alien species are recognized as the second leading cause of biodiversity loss and species extinction worldwide, with zoochoric dispersion being a key factor for the success of invasive organisms as they can favor the germination of these species. We performed a study in the southern Brazil involving three generalist species with abundant and wide amount of distribution in Latin America, with the objective of evaluating seed ingestion by positive criteria about its germination. We investigated the role of bird digestion on the germination of a native pioneer species, the Brazilian pepper?Schinus terebinthifolia, an invasive alien species in many parts of the world. We compared the germination of this native with those of the invasive Australian cheesewood (Pittosporum undulatum) concurrently. Interestingly, the effect of potentiating germination was more intense in the introduced species than for the native species. Pitangus sulphuratus is an important potential disperser for the germination of P. undulatum seeds, enabling the colonization of new areas in the Atlantic Forest of southern Brazil. |
