Résumé

An evaluation was made of the degree of toughening of asparagus during storage through a study of the morphological and cellular differences of the xylem vascular bundles as a function of cultivar, thickness of spear (thick: diameter of 15-25 mm; medium: diameter of 10-14 mm; or thin: diameter of less than 10 mm) and portion of the spear (7 cm long pieces corresponding to tip, middle and base of spear). Light microscopic examinations were carried out to determine the thickness of cell walls to quantify the extent of toughening. At the same time a study was made of the fractions of dietary fibre of the spear by means of chemical extraction techniques. Statistically significant differences were found between cultivars, thickness and portions of the spear.
