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).
