Semivariograms resulting from samplings were adjusted to the spherical theoretical model Cuadro 1, which shows the level of rust severity, and were expressed as specific points within the plot compared to the rest of the sampled points. Results suggest that the disease could have developed from contaminated materials such as corms , that are the primary source of inoculum.
Los semivariogramas obtenidos a partir de los muestreos tuvieron un ajuste al modelo teórico esférico Cuadro 1, lo cual es indicativo de la severidad de la roya al expresarse en puntos especificos dentro de la parcela respecto al resto de los puntos muestreados lo que soporta la probabilidad que la enfermedad se originó a partir de material contaminado como son los cormos que representan la fuente primaria de inóculo.
