dc.description.abstract A research was performed to determine the susceptibility of the kenaf plant (Hibiscus cannabinus) in presence of certain pathogens commonly found in the soil. The effect of the nematode Meloidogyne incognita and the soilborne’s fungi Fusarium oxysporum, Rhizoctonia solani and Macrophomina phaseolina were evaluated. The interactions between the nematode and the soilborne fungi were also studied. Experiments were established in a greenhouse to determine the inoculum levels of Meloidogyne incognita required to cause damage to plants. For the experiment of Meloidogyne incognita, kenaf’s plants died with inoculum levels of 12,000 eggs/J2. In the experiment of the soilborne fungi, it was demonstrated that Fusarium oxysporum reduced the height of the kenaf’s plant; while Rhizoctonia solani resulted non pathogenic to the crop. The interaction between Meloidogyne incognita/Macrophomina phaseolina increased the weight of the kenaf’s roots; however the interaction Meloidogyne incognita/Fusarium oxysporum had the opposite effect. en_US
dc.description.abstract En un estudio realizado se evidenció la susceptibilidad de la planta kenaf (Hibiscus cannabinus) ante la presencia de determinados patógenos habitantes del suelo. Para esto se evaluó el efecto del nemátodo Meloidogyne incognita y los hongos Fusarium oxysporum, Rhizoctonia solani y Macrophomina phaseolina; además del efecto causado por la interacción de ambos patógenos. Se realizaron experimentos en invernadero con el propósito de determinar niveles de inóculo de Meloidogyne incognita capaces de producir daño a plántulas. Para el experimento de Meloidogyne incognita, las plantas de kenaf murieron al recibir el nivel de inóculo de 12,000 huevos/J2. Al inocular hongos fitopatógenos, se comprobó que el hongo Fusarium oxysporum afecta negativamente el crecimiento de las plantas de kenaf, mientras Rhizoctonia solani resultó ser no patogénico al cultivo. Se determinó que la interacción entre Meloidogyne incognita y Macrophomina phaseolina aumenta el peso fresco de raíz de la planta, contrario a la interacción de Meloidogyne incognita y Fusarium oxysporum. en_US
