abstract A method and process were developed to nondestructively measure the length of the floral stalk in Belgian endive Cichorium intybus L. Current X-ray technology proved to be a feasible method. A detection algorithm was developed based on the minimal transmitted intensities along the length. The method is very accurate with an absolute precision of 4.9 mm and allows the study of the influence of storage conditions and time on the Belgian endive internal quality. The growth of the floral stalk is an exponential function of the temperature and is variety dependent.
