Abstract
A study was conducted to determine whether hollow heart potatoes might be separated from normal ones by a nondestructive method based on an objective criterion. The profile of x-ray density measured along the longitudinal axis of each of 106 tubers was recorded and then analyzed by computer. The second derivative of the x-ray density profile provided a basis for detecting hollow heart. All of the defective tubers were separated without inclusion of any normal tubers. The incidence of hollow heart was 21.4%.
Resumen
Un estudio fue conducido para determinar si se pudiera encontrar unos criterios objetivos e indestructables que pudieron separar las patatas con corazones huecos de las que eran normales. Las caracteristicas transmitidas por el rayo X de 106 patatas fueron medidas. Una curva del rayo X, perfilada y con densidad, a lo largo del axis longitudinal de cada tubérculo fue apuntada y analizada por una técnica del computor. Un segundo derivado de la curva del rayo X con densidad, proveyó una base para descubrir un corazón hueco. Todos los tubérculos defectivos fueron separados sin incluir ningunos tubérculos normales. La incidencia de corazones huecos era 21.4%.
