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.
This study was carried out during 2015to determine some chemical Composition
of the fruit of some distribution phenotypes of Prunus ursina in different regions of
Westrens of Syria.
six natural distribution sites were determined(Duerbsndiana-Alnab
een-Alshohtte-
Helata-Btmazah-Wadeheleen), and 35 trees were determined as samples.
Fruits were harvested and following parameters were determined: dry matter, total
acids (T.A), total soluble solids (T.S.S), and total sugar.
Statistical analysis of investigated phenotypes showed that There were differences
between dry matter, total soluble solids (T.S.S), and total sugar between two groups.
the trees were distributed in two groups (A, B) .The results showed existence of most
trees in whole sits, while (J6 and KA6) were distributed in two different sits(Btmazah and
Duerbsndiana) .
This study was carried out during 2011- 2013 to determine some qualitative and
quantitative features of some distribution trees of Prunus ursina in different regions of
Syrian coast.7 natural distribution sites were determined and 43 trees were det
ermined as
samples.
22 features of different plant portions were studied using biological
measurements(leaves, flowers, fruits, seeds). Statistical analysis of investigated phenotypes
showed that trees were distributed in 5 groups (A, B, C, D, E) each one considered
phenotype. The results showed existence of one phenotype in several sites (C, D, E) while
(A and B) phenotypes were distributed in one site, while (A) phenotype was located in one
tree only in " Nabeen" site whereas (B) phenotype was located on only half investigated
trees in "Btmaze" site, while the other half distributed in (D) phenotype.
A study was conducted to investigate the presence of root knot nematode
(RKN) and other plant parasitic nematodes associated with Syrian most
important peach plantation areas. 126 soil and root samples were taken from
63 peach orchards of Ghuta, Z
abadani, Yabrod, Syrghaya and Kharabo at
Damascus governorate, and Tezeen, Kufr Ton, Khattab, Arzeh, Sheha,
Qamhaneh, Balhasen, Rastan, Mhardeh, Salmieh, Sqalbieh and Sharaya at
Hama governorate.
