Resumo: | With the aims to study the efflux of H+ or OH- due nitrogen sources on the process of infection of Fusarium oxysporum f. sp. phaseoli in the rhizosphere of two beans cultivars Diamante Negro (susceptible) and Ouro Negro (more resistant), a series of experiments were done in greenhouse and growth chamber. Were applied to three different sources of nitrogen (N-N2 N-NO3- and N-NH4+) in three nitrogen concentrations (0, 30 and 120 kg ha-1), in plants grown in clay and sand soil. In addition, an experiment was conducted with different concentrations of inoculum of Fusarium (0, 10 ? and 106 conidia mL-1) in greenhouse in order to know the concentration that would affect the infection and when applied the fungi. Overall, the results suggested that nitrate decreased the infection process of Fusarium and ammonium increase. The association between nitrate with the cultivar more tolerant Ouro Negro, decreased the perceptual infection of fungi. The source of nitrogen influence of pH of rhizosphere occurred interaction with the type of soil. In all the experiments, found lower numbers of nodules. The concentration of inoculum or the times of inoculation not produce effect in the perceptual of infection. |

Os experimentos foram instalados em c?mara crescimento ou em casa de vegeta??o. O objetivo deste trabalho foi o de analisar a influ?ncia da libera??o OH- ou H+ devido ao uso de fontes nitrogenadas na infec??o do fungo. Foram utilizadas tr?s fontes de nitrog?nio (N-N2, N-NO3 ? e N-NH4+) e diferentes doses de nitrog?nio (0, 30 e 120 kg ha-1) com plantas inoculadas com o referido fungo, crescidas no substrato areia ou em solos com diferentes teores de argila. Tamb?m foi realizado um experimento utilizando diferentes concentra??es de in?culo do Fusarium (0, 10? e 106 con?dios mL-1) com o objetivo de analisar qual concentra??o afetaria mais a infec??o na presen?a de fontes nitrogenadas. Foram analisados, o percentual de infec??o do Fusarium, o pH da rizosfera e n?o rizosf?rico, massas da parte a?rea e ra?zes secas, e o n?mero de n?dulos em diferentes ?pocas de amostragem. De modo geral foi observado que a fonte nitrato diminuiu o processo de infec??o do Fusarium e a fonte am?nio aumentou. Foi confirmado que a cultivar Ouro Negro ? mais tolerante ao fungo e que quando associada ? fonte de nitrog?nio nitrato aumentou ainda mais a resist?ncia. O pH da rizosfera e n?o rizosf?rico foram influenciados pela fonte de nitrog?nio: nitrato aumenta, e am?nio diminui. Os dados do trabalho sugeriram haver intera??o entre a fonte de nitrog?nio x dose x cultivar x solo. O n?mero de n?dulos encontrado nas condi??es experimentais foi baixo, especialmente nas amostragens na fase inicial do ciclo.Submitted by Jorge Silva (jorgelmsilva@ufrrj.br) on 2017-05-26T20:53:49Z No. of bitstreams: 1 2010 - Joice de Jesus Lemos.pdf: 529861 bytes, checksum: 869aef193d0f1b7b1b385f7ee3a2de73 (MD5)Made available in DSpace on 2017-05-26T20:53:49Z (GMT).

description |
With the aims to study the efflux of H+ or OH- due nitrogen sources on the process of infection of Fusarium oxysporum f. sp. phaseoli in the rhizosphere of two beans cultivars Diamante Negro (susceptible) and Ouro Negro (more resistant), a series of experiments were done in greenhouse and growth chamber. Were applied to three different sources of nitrogen (N-N2 N-NO3- and N-NH4+) in three nitrogen concentrations (0, 30 and 120 kg ha-1), in plants grown in clay and sand soil. In addition, an experiment was conducted with different concentrations of inoculum of Fusarium (0, 10 ? and 106 conidia mL-1) in greenhouse in order to know the concentration that would affect the infection and when applied the fungi. Overall, the results suggested that nitrate decreased the infection process of Fusarium and ammonium increase. The association between nitrate with the cultivar more tolerant Ouro Negro, decreased the perceptual infection of fungi. The source of nitrogen influence of pH of rhizosphere occurred interaction with the type of soil. In all the experiments, found lower numbers of nodules. The concentration of inoculum or the times of inoculation not produce effect in the perceptual of infection. |
