Abstract
Zizyphus jujuba Mill. belongs to the Rhamnales order, Rhamnaceae family, Rhamnus genus. The genus includes about 40 species native to tropical and subtropical regions of both hemispheres, as well as the Mediterranean region. Species Zizyphus jujuba Mill. it is native to SW Asia, has ornamental features and is found spontaneously on the Danube coast. The first cultivated varieties were introduced at the Faculty of Horticulture in Bucharest in Shanxi Province, China in a joint research project in 1997. In our study, the fruits were harvested from two genotypes in the Botanical Park of Timisoara. For the harvested fruits were analyzed: fruit weight (g), seed weight (g), fruit length (mm), fruit width (mm) and chemical analyses were performed: soluble dry matter (%), C vitamin (mg 100 g-1), total potassium content (mg 100 g-1) and protein (%). In the analyzed fruits, the soluble dry matter varied between 28.3-29.81%, C vitamin between 247.97-288.17 mg 100g-1, proteins between 4.84-5.63% and potassium between 79.53 -79.63 mg 100 g-1.
