Abstract: 

The research was conducted in (2018-2019), in Hama: Al-Ghab and Lattakia: Kassab. Experiment was applied on (1296) seeds of L.nobilis, according to (7) treatments, namely: (T1) the control, (T2) the cold-moist stratification (25 days), (T3) the cold-moist stratification (50) days, (T4) treated with gibberellic acid (1000) ppm, (T5) treated with gibberellic acid (3000) ppm, (6T) treated by mechanical scratching, (7T) treated with seed coat removed. The results showed that the treatment (T7) gave the highest percentage of germination (81.48-88.88)% in the two stations (Al-Ghab – Kassab), while the control treatment (T1) achieved the lowest germination rate (14.81-18.51)%. When studying germination indicators, treatment (T3) seeds of Kassab in Station (Al-Ghab) excelled in germination speed (21.29) seed/day and excelled in degree of homogeneity (2.62). seed/day over the rest of the treatments.

Keywords: Laurus nobilis L., Cold-moist stratification, Germination, Gibberellic acid (GA₃), Scarification mechanical.
