Abstract:

This study targets to examine the stimulating effect of Nummularine aqueous extracts from the stem bark of Ziziphus nummularia on the growth and germination of faba bean (Vicia faba L.) at several concentrations (50, 100, and 150) µg/ml compared to control treatment employing the direct irrigation method. Results have revealed that the aqueous extracts of Nummularine had an evident stimulating effect in their various concentrations toward the growth and germination of the faba bean (Vicia faba L.). Over and above, the concentration of 150 µg/ml showed the strongest stimulating effect compared to the control treatment and to other concentrations where the length of the shoot system reached 23.9 cm, whilst the seed germination rate was 98%. The control treatment at the concentration of 0 mg/ml of the aqueous extract showed the weakest stimulating effect where the length of the shoot system recorded 4.6 cm, whilst the seed germination percentage was at 83%.
