The objective of this study was to determine the impact of allelopathic potentials of different extract of Citrullus colocynthis shoot system on germination and metabolite accumulation in Vicia faba and Hordeum vulgare. Citrullus colocynthis was collected from Al-Thomamah region, Saudi Arabia and the experimental design was a complete randomized with three replicates. Water, chloroform and methanol extracts from dried shoot system of Citrullus colocynthis with different concentrations (25, 50, 75 and 100%) were prepared, in addition to distilled water (as Control). The results showed that great reduce in germination of Hordeum vulgare but Vicia faba was not affected. The seedling growth was more sensitive than the seed germination. The allelopathic effects of Citrullus colocynthis on growth showed slightly increase in shoot and root lengths. The leaf area was decreased in Hordeum and Vicia for all concentrations. Pigments (Chlorophyll A, B and caroteins) were increased in Vicia for all concentrations of extracts, and showed variations in Hordeum compared to control. Results also showed decrease of carbohydrates and increase of proteins for the both studied plants
