Detection of asymptomatic Solanum lycopersicum L. plants infected with Fusarium oxysporum using reflectance VIS spectroscopy

| description | Asymptomatic plants are reservoirs of pathogens because they can remain infected most of the development cycle, becoming a source of contamination for the rest of the crop. The objective of this study was to evaluate a method of detection and discrimination of two F. oxysporum isolates on tomato plants using reflectance spectroscopy in the VIS region. The incidence of the fungal isolate from the purple passion fruit plants (F05) was greater than that observed in the strain isolated from the tomato plant (F07), with values of 60.0% at 11 days and 81.8% at 22 days; the incidence present in the plants with strain F07 was 30.0% and 64.3% in the evaluated period. The F05 strain showed better grouping in both periods of time, both in the Principal Component Analysis and Linear Discriminant Analysis, than the controls, as did the F07 strain. These results suggest that reflectance spectroscopy in the VIS is a sensitive and reliable method that may be suitable for early diagnosis of plant diseases. |

Las plantas asintomáticas son reservorios de patógenos, ya que pueden permanecer infectadas la mayor parte de su ciclo de desarrollo, convirtiéndose en fuente de contaminación para el resto del cultivo. El objetivo de este estudio fue evaluar un método de detección y discriminación de dos cepas de Fusarium oxysporum en tomate usando espectroscopia. La enfermedad en las plantas de tomate inoculadas con la cepa aislada de gulupa (F05) fue mayor a la observada en la cepa aislada de tomate (F07), presentando valores de 60,0% (11 días) y 81,8% (22 días); la cepa F07 presentó incidencias de 30,0 y 64,3% en ambas mediciones. La planta infectada con la cepa F05 fue mejor discriminada en el periodo de incubación de la enfermedad en ambos periodos de tiempo en los Análisis de Componentes Principales (PCA) y Análisis Discriminantes Lineales (LDA) realizados con los controles en comparación con la cepa F07. Estos resultados sugieren que la espectroscopia de reflectancia VIS es un método sensible y confiable que puede ser adecuado para el diagnóstico temprano de enfermedades en plantas.
