This research work was carried out in the nursery field of the Faculty of
AGgriculture in Tishreen Univesity during the spring growing season of 2012, it involved
studying some chemical characteristics of potato tubers of Five newly introduced vari
eties
of potato ( Atlas, Bureen, Bomba, Rumba and Orla), in comparision with Spunta variety as
a control.
It was showed that the hieghest large tuber were recorded in Atlas ,Burren and
Bomba. Bomba variety showed hieghest standards tubers (7.8 Kg/ m2). It was showed also
the hieghest dry matter (DM=20.5 %), and Ash content (1.01%) in tubers, were recorded in
Rumba variety. Bureen and Spunta varieties showed hieghest values of starch contents
(14.5 % and 14.4%) respectively. While Vitamin C (VC ( , was encountered ( 19.36, 17.6,
and 17.6 mg / 100g) for Rumba, Spunta and Bureen respectively. Also, the highest values
for protein content (1%) and the soluble solid (5%) in tubers were found in Rumba
variety.
In the present study¸ twelve parameters of Capparis spinosa were studied which are: plant length¸
number of main branches¸ number of leaf doubles, leaf length, leaf width, leaf area¸ number of budes,
number of flowers, number of fruits, weight of t
he fruits, number of seeds, weight of seeds. Statistical
analysis have been done using mean¸ variation¸ A.F.C.
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.
