Abstract
Among different populations of monogerm sugarbeet fruits, those characterized by the lowest percentages of germination exhibited the lowest percentages of mechanical deoperculation (removal of the fruit cap under the sole imbitition pressure). X-ray radiography of dry fruits allowed a classification based on the space occupied by seeds inside the fruit cavity and further established a correlation between the fruit type (filled, semi-filled, empty), passive deoperculation and germination. The degree of correlation depended on the amount of bedding water which further conditioned the fruit surrounding water film.
