Capparis decidua is an of important tree species. Although it has economic importance, little or no information is available of propagation as well as its chemical composition. This study was undertaken to find out: * The optimum conditions for seed germination and seedlings growth in the nursery. * To compare between the three provenances taken from the localities namely El Obeid, El Khojlab and Soba. Parameters measured were: weekly germination percentage, height, root length (cm), stem and root fresh weight (g), number of leaves/plant, to study the impact of shade (shaded, partially shaded), soil (sand and sand + clay loam mixture 1:1) two watering intervals (two and four days) on the production of Capparis decidua seedlings. The study suggests that the best conditions to produce seedlings were to sow seeds directly in polythene bags containing sand + clay loam mixture (50:50%) irrigated every two days under partial shade in form of overhead shade. El Khojlab seeds gave the best performance under most treatment conditions. On the other hand, the analysis performed have shown various ranges of chemical composition of different plant parts with no significant differences between the same parts collected from different sites. Most tree parts have shown relatively high level of moisture (5.00-38.80%), crude protein (4.31-8.69%), crude fibre (8.06-40.13%), ash value (5.88-13.42%), calcium (0.68-1.81%), magnesium (0.21-0.39% phosphorus (0.12-0.25%), potassium (0.71-2.20%), iron (49.33-16% mg/g). In terms of sodium concentration all tree parts recorded low level sodium (0.03-0.06%). The most common constituents are flavonoids, unsaturated sterols and/or triterpenes, tannins and alkaloids which are detected in the plant parts, while cardenolides and saponins were devoid in the fruits.) Also roots, branches and fruits were shown to be devoid of anthraquinone glycosides. A general characteristic is the absence of cyanogeinc glycosides. Generally, these active ingredients are screened in medicinal plants.
