This research was carried out during two seasons 2014 – 2015 to study effect of seed coats on germination of endocarp, seed and embryos of two wild genotypes (M1, M2) of Mahaleb rootstock (Prunus mahaleb L.) prevailing in Alhaffa area, Lattakia. The experiments were done at Lattakia Scientific Agricultural Research center and Faculty of Agriculture at Tishreen University. The Results of the seeds planted on agar 0.7% in dark at 15 C° showed that no germination of the M1 endocarp VS late and low germination at 10% for the M2 endocarp starting after 98 days. As for seeds, the germination was (66.66%) and (53.33%) for M1 and M2, respectively. Removal of the woody coat (endocarp) and seed coat makes the germination faster. the embryos germination was (80%) and (60%) for M1 and M2, respectively.
