| description | This study used greenhouse conditions to determine the hyperspectral responses of cape gooseberry (Physalis peruviana L.) plants inoculated with different Fusarium oxysporum f. sp. physali densities because the causal agent of vascular wilt generates great economic losses for farmers. A completely randomized design with four replicates was established. The evaluated treatments were inoculum densities 0.0, 1.0·103 and 1.0·106 conidia/mL of the pathogen. The inoculation was done with immersion of roots in conidia suspensions. The spectral response was directly measured on the plant leaves with a spectroradiometer. Non-invasive detection in the P. peruviana - F. oxysporum pathosystem with reflectance values was used with different spectral indices related to the visible and Red Edge, which were calculated and correlated with the disease variables. The treatments showed significant differences in the visible spectrum starting 14 days after inoculation with higher reflectance values. The chlorophyll index at the red edge (ChRE), the modified chlorophyll absorption index (MCARI), the simple ratio index (SR) and the Zarco & Miller index (ZM) showed highly significant correlations with the area under the disease progress curve for leaves (AUDPCL), leaf area and fresh weight of the aerial part of the plants. This study showed the potential of spectral patterns for the detection and study of Fusarium wilt in P. peruviana. |

El objetivo de este estudio fue determinar en condiciones de invernadero la respuesta hiperespectral de las plantas de uchuva (Physalis peruviana L.), inoculadas con diferentes densidades de Fusarium oxysporum f. sp. physali, agente causal del marchitamiento vascular que genera grandes pérdidas económicas para los agricultores. Se estableció un diseño completamente al azar con cuatro repeticiones. Los tratamientos evaluados fueron densidades de inóculo 0.0, 1.0·103 y 1.0·106 conidios/mL del patógeno. La inoculación se realizó por inmersión de raíces en la suspensión de conidios. Para la evaluación de la respuesta espectral, se usó un espectroradiómetro midiendo directamente las hojas de la planta. Para la detección no invasiva en el patosistema P. peruviana - F. oxysporum, con los valores de reflectancia se calcularon diferentes índices espectrales relacionados con el Red Edge y se correlacionaron con las variables de la enfermedad. Los tratamientos mostraron diferencias significativas en el espectro visible a partir de 14 días después de la inoculación con los mayores valores de reflectancia. El índice de clorofila en el Red Edge (ChRE), el índice de absorción de clorofila modificado (MCARI), el índice de relación simple (SR) y el índice de Zarco and Miller (ZM) mostraron correlaciones altamente significativas con el área bajo de la curva del progreso de la enfermedad (AUDPCL), el peso fresco de la parte aérea de la planta y el área foliar. El estudio mostró el potencial de las respuestas espectrales para la detección y el estudio del marchitamiento vascular por Fusarium en P. peruviana.
