Thirteen phenotypes of cultivated wild olive were selected during 2007- 2008 from four orchards in Mesiaf region, to study oil percentage and fatty acids contents in these types for choosing types for oil production, in order to propagate and cons erve them in a germplasm, and then to be cultivated because they have adapted to local climate in this region. The results were analyzed statistically by using Gen-State program to calculate least significant differences between values. The results confirmed the high biodiversity in these studied types, and they were classified into five groups according to their oil percentage and contents of oleic acid. The oil percentage ranged from 3.9 to 27.3 %, and the fatty acids had significant differences between them, the oleic acid was in olive oil between 56.7 and 75.5%. The types P1-1 and p1-3 showed the best results for producing oil.
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. Th e 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.
The study was conducted in four sites belonging to the Sheikh Badr district in Tartous province. Ten different types were identified according to international standards. During the 2016 and 2017 growth seasons, readings were recorded for phenotypi c parameters as well as physical and chemical analysis of fruit clusters. The studied types differed in many characteristics. The results of the cluster analysis showed the distribution of the studied types in two groups with a variance of 93%. The mean weight of the cluster varied between the medium (349 g) and the large (1140.45 g). The ratio of total dissolved solids (TSS) between the low (12.75%) and high (18.82%). the acidity between the very low (3.53 g/l) and medium (6.38 g/l).
