Resumo: Knowing the maturation of the Acrocomia aculeata (macaw palm) fruit is decisive for harvest to be performed when the fruit has a higher content and quality of oil. There are different approaches to monitor maturation and they can be classified as destructive and non-destructive. Variables obtained by optical instruments have been used to determine maturation stage. The present study evaluated the relationship between the biological activity measured by the optical technique of biospeckle laser and firmness, measured in the Acrocomia aculeata fruit pulp between the 41st and 61st week after flowering. The biological activity was quantified by biospeckle images, while the fruit pulp firmness was determined by digital penetrometer. Correlations between variables were evaluated during maturation and in the senescence of fruits. According to the results, significant correlation between biological activity and firmness was found for both evaluated conditions, demonstrating that biospeckle laser can be an effective non-invasive indicator of Acrocomia aculeate fruit maturation assisting in the determination of the moment of harvest.

Existem diversas abordagens para monitorar a maturacao, classificadas como destrutivas e nao destrutivas. Variaveis obtidas por instrumentos oticos vem sendo utilizadas para determinar, de forma nao destrutiva, o estadio de maturacao. Neste trabalho foram avaliadas a relacao entre a atividade biologica mensurada pela tecnica otica do biospeckle laser e a firmeza da polpa dos frutos de Acrocomia aculeata entre as 41a e 61a semanas de maturacao, apos a florada. A atividade biologica foi quantificada a partir das imagens do biospeckle enquanto a firmeza da polpa dos frutos foi determinada por um penetrometro digital. Foram avaliadas as correlacoes entre as variaveis durante a maturacao e na senescencia dos frutos. A partir dos resultados foi constatada correlacao significativa entre atividade biologica e firmeza para as duas condicoes avaliadas demonstrando que o biospeckle laser pode ser um indicador eficiente nao invasivo da maturacao dos frutos da Acrocomia aculeata auxiliando na determinacao do momento de colheita.Revista Brasileira de Engenharia Agricola e Ambiental2019-01-24T13:06:54Z2019-01-24T13:06:54Z2017-01info:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlepdfapplication/pdf1807-1929https://doi.org/10.1590/1807-1929/agriambi.v21n1p68-73http://www.locus.ufv.br/handle/123456789/23175engVolume 21, Número 1, Páginas 68- 73, Janeiro 2017Costa, Anderson G.Pinto, Francisco A.
