The present investigation was carried out during 2003 and 2004 seasons to study the morphological characteristics (tree dimensions as well as vegetative characteristics of zig-zag branches, branchlets and leaves) and fruit quality (fruit characteristics and fruit chemical constituents) of five jujube varieties namely: Li, Lang, Toffahi, Zaytoni and Date growing at Horticulture Research institute, Giza Governorate, Egypt. Results clearly showed wide significant differences in all vegetative growth characteristics of the studied jujube varieties. As for tree dimensions, Toffahi and Zaytoni varieties recorded the highest values of tree height, top circumference and trunk girth in both seasons. Concerning vegetative growth the zig-zag branches considered the main part of the jujube tree. Also, average length of zig-zag branches, number of nodes i branch and internodes length differ significantly according to variety and season. in addition, branchlets do not form a part of the permanent of jujube tree. Moreover, Toffahi variety exhibited the maximum average number of branchlets, whereas, Li and Date varieties appeared to be the minimum in this concern. Leaf length, width and leaf area showed significant difference among the five studied varieties. Jujube varieties varied significantly in fruit dimensions and fruit lengthi‘width ratio in both seasons. Date variety recorded the highest values of fruit length fwidth ratio (i.e. of elongate shape), meanwhile; Toffahi variety recorded the lowest ones (i.e. fruit of about round shape). More over, Li and Lang varieties had the heaviest average fruit and pulp weights. Also, fruits with the heaviest values have the highest pulpfseed ratio and visa versa. Slight differences were recorded in the average seed weight among such varieties. This may be due to the presence of high percentage of undeveloped seed kernels in the jujube varieties. As for chemical constituents, Date variety recorded the highest values of dry matter %, total soluble solids % (TSS), ascorbic acid %, sugars, protein, and carotenoids mgf100g. Whereas, the highest values of moisture %, total acidity%, protein, av. pectin (mgf‘lODg) appeared in Toffahi variety. However, Lang variety exhibited the highest polyphenols content, while, Date and Zaytoni varieties recorded the lowest ones. Generally, Date and Toffahi varieties considered as a good source of different chemical components. From the above mentioned results, it may be concluded that Li, Lang and Date varieties have good characteristics and can be recommended to grow under the same conditions of this study.
