The present study focused on the allelopathic effects of the aqueous and methanol extracts of Mesembryanthemum forsskalii Hochst. ex Boiss. on germination and seedling growth of Malva parviflora and Plantago ovata. M. forsskaliii was collected from Al-Jouf area, Saudia Arabia. The dried shoot system of M. fosskalii was used to prepare water and methanol extracts with different concentrations (25, 50, 75 and 100%) and distilled water as the control. The results showed that the aqueous and methanol extracts of M. forsskalii contained phenolic compounds and flavonoids that might be embroiled as allelochemical agents. Petri-dish trial showed that the two extracts at all concentrations reduced total germination percentage. Pot experiment indicated variations in seedlings germination and growth between M. parviflora and P. ovata in response to aqueous and methanol extracts of M. forsskalii. On growth stage the shoot and root lengths were decreased probably due to the allelopathic effects of M. forsskalii. The fresh and dry weights of shoot were inhibited with increase in concentration of aqueous and methanol extracts. In M. parviflora and P. ovata the leaf area was decreased under all concentrations. The chlorophyll a, b and carotenoids (pigments) were decreased in M. parviflora and P. ovata for all concentrations of extracts, but methanol extract increased chl. a only in M. parviflora compared to control. Flavonoids, saponins, tannins, carbohydrates, glycosides and phenolic are the allelochemical compounds released from the M. forsskalii into aqueous and methanol extracts which inhibited germination and growth of the studied plants.
