This study was carried out in the cold storage rooms of the Horticulture Research Institute, Giza Governorate during the two succssive seasons of 198/1999 and 1999/2000. The aim of this study was to identified suitable storage conditions, storage media, and storage temperature for ; ‘Fuseau’ and other local jerusalem artichoke cultivars. Tubers were stored either without media (control), in peat moss, or in sand. All treatments were cold stored at 0 or 5 0C. A complete randomized design with three replicates was used. Data were recorded on weight loss, decay, sprouting, shrinkage, discolouration and some chemical component of tubers. Results indicate that ‘fusea’ showed a lower percent of decay compared with the other local cultuvars. Regarding the effect of storage media, tubers stored without medium (control) gave the best results for weight loss, decay, dry matter and reducing sugars. In respect to the two tested temperatures, no significant effect on weight loss, sprouting, shrinkage, discolouration, decay, dry matter, inulin, carbohydrates and reducing sugars of tubers were noted.
