Gabriela Queiroz Pelzer 02 June 2010 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Objetiva elucidar quais mecanismos de antagonismo são responsáveis pelo biocontrole da murcha-de-esclerócio e que fatores estão envolvidos na promoção de crescimento em tomateiro por meio de rizobactérias. Os testes foram realizados in vivo e in vitro, em que se verificaram: a capacidade de produção de enzimas líticas, antibiose por meio de compostos voláteis e difusíveis, colonização de raízes, produção de sideróforos, metalismo de carbono, produção de ácido indol acético, fixação biológico de nitrogênio, solubilização de fosfato de cálcio e promoção de crescimento do tomateiro em condições de casa-de-vegetação / This research was aiming to elucidate the antagonism mechanisms responsible for the biocontrol of southern blight and the elements involved in growth promotion in tomato by rhizobacteria. The experimental assays were performed in vivo and in vitro, and the following characteristics evaluated: production of lytic enzymes, antibioses by volatiles and diffusible compounds, root colonization, siderophores production, carbon sources metabolism, indole acetic acid production, nitrogen fixation, calcium phosphate solubilization and tomato growth promotion in greenhouse conditions

Estes organismos, por produzirem estruturas de resistência na ausência de hospedeiros e/ ou condições climáticas desfavoráveis, inviabilizam o controle do patógeno. A preservação de fungos por longos períodos é importante para que pesquisas possam ser realizadas a qualquer tempo. O método de manutenção destes organismos requer que sejam conservados em baixa atividade biológica para preservar as características de esporulação e patogenicidade. O objetivo deste trabalho foi desenvolver metodologias para produzir, avaliar a sobrevivência e preservar as estruturas de resistência dos fungos Fusarium oxysporum f.sp. lycopersici raça 2, Macrophomina phaseolina, Rhizoctonia solani GA4 HGI, Sclerotium rolfsii, Sclerotinia sclerotiorum e Verticillium dahliae. O primeiro experimento foi feito no delineamento de parcelas inteiramente casualizadas em que a sobrevivência das estruturas de resistência dos seis fungos foi avaliada mensalmente por seis meses, em condições de campo e de laboratório. Para tanto, estruturas de cada fungo, produzidas através das metodologias desenvolvidas, foram enterradas no campo a 10 cm de profundidade e outras mantidas no laboratório. O objetivo deste experimento foi verificar a eficiência das metodologias para manter e também para avaliar a capacidade da sobrevivência dos patógenos, permitindo desta forma, manusear as estruturas de resistência de todos os fungos estudados. No segundo experimento, frascos de 500 mL (duas repetições/fungo) contendo estruturas de resistência, produzidas através das 2 metodologias desenvolvidas, foram mantidos em temperatura natural de laboratório, de refrigeração (º5C) e de freezer (-20ºC) para determinar a melhor condição para preservar as estruturas de cada fungo...
