Resumo: | The pineapple (Ananas comosus) is one of the most important crops in the state of Pará, this being the third largest producer in the country. The increase in planted area in the state, coupled with the importation of plants not inspected, favored the spread of the fungus Fusarium subglutinans f. spp. ananas, which causes the disease called fusarium or gummosis. 0 6 aim of this study to evaluate the survival period of F subglutinans f. spp. pineapple in natural soils from different sources. The experimental design was completely randomized factorial of obeying the 3x7x10 (three provenances of soils, seven incubation periods and ten repetitions), the origins of the soils are: (1) Salvaterra, Marajó, For (Yellow Latosso medium texture), (2) the Guama River Estuary within UFRA (Gley Little distrophic Hilmico), (3) area of land within the UFRA (Latosso Yellow Alico medium texture), with incubation periods being 0, 5, 10, 15, 20, 25 and 30 days with 10 replicates for analysis, and the analysis made in each incubation period with a repetition consists of two polyethylene containers 200 ml capacity containing 50 g of soil each. For this soil infestation a concentration of 105 conidios.m1-1 suspension was used, adding to the suspension 5M1. Assessments of pathogen survival were made every five days amid PCNB, for thirty days, and prepared two plates per replicate. The pathogen was reduced to negligible levels within thirty days their survival in natural soils. The residue of pineapple, contained in soils cultivated with culture, did not influence the survival of the pathogen after thirty days. In sterilized soil, F subglutinans f. spp. dwarf survived the saprophytic way for long periods, the type of organic matter in the soil from Salvaterra did not influence survival of F subglutinans f. spp. dwarf for soil sterilization vertical autoclave was used. |

O aumento da área plantada no Estado, aliada a importação de mudas não fiscalizadas, favoreceu a proliferação do fungo Fusarium subglutinans f. sp. ananas, que acarreta a doença chamada de gomose ou fusariose. 0 objetivo do presente trabalho 6 avaliar o período de sobrevivência de F subglutinans f. sp. ananas em solos naturais de diferentes procedências. O delineamento experimental foi inteiramente casualizado obedecendo ao esquema fatorial de 3x7x10 (três procedências de solos, sete períodos de incubação e dez repetições), as procedências dos solos são: (1)Salvaterra, Marajó, Para (Latosso Amarelo textura media), (2) Estuário do rio Guamá dentro da UFRA (Gley Pouco Hilmico distrofico), (3) área de terra firme, dentro da UFRA (Latosso Amarelo Alico textura media), com os períodos de incubação sendo 0, 5, 10, 15, 20, 25 e 30 dias, contendo 10 repetições por analise, sendo as analises feitas em cada período de incubação tendo a repetição constituída de dois recipientes de polietileno de 200 ml de capacidade contendo 50 g de solo cada. Para infestação deste solo foi utilizada uma concentração de suspensão de 105 conidios.m1-1, adicionando-se 5m1 da suspensão. As avaliações de sobrevivência do patógeno foram feitas a cada cinco dias em meio PCNB, durante trinta dias, sendo preparadas duas placas por repetição. O patógeno teve sua sobrevivência reduzida a níveis insignificantes ate trinta dias em solos naturais. O resíduo de abacaxizeiro, contido em solos cultivados com a cultura, não influenciou na sobrevivência do patógeno apos trinta dias. Em solo esterilizado, F subglutinans f. sp. ananas sobreviveu na forma saprofítica por longos períodos, o tipo de matéria orgânica encontrada no solo proveniente de Salvaterra teve influencia na sobrevivência do F subglutinans f. sp. ananas, para a esterilização do solo foi utilizado um autoclave vertical.Universidade Federal Rural da Amazônia/UFRA2011-05-18info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ajaes.ufra.edu.br/index.php/ajaes/article/view/218Amazonian Journal of Agricultural Sciences Journal of Agricultural and Environmental Sciences; Vol 49 No 1 (2008): RCA; 157 - 172Revista de Ciências Agrárias Amazonian Journal of Agricultural and Environmental Sciences; v. 49 n. 1 (2008): RCA; 157 - 1722177-87601517-591Xreponame:Revista de Ciências Agrárias (Belém.
