نفذت الدراسة خلال الفترة (15/1–15/8/2004) في خمسة مواقع تمثل أهم مناطق زراعة الرمـان و إنتاجه باليمن، و قد استخدم في هذه الدراسة ثمانية طرز من الرمان المحلي هي (طائفي، عرقبي، مليس الحداء، خازمي، صماطي، خضاري، صيني، مليس الروضة) بالإضافة إلى نوع الرمان البري السوقطري. تم التوصيف الشكلي للأوراق و الأزهار و الثمار و البذور و حساب وزن الثمرة، و نسبة و سمك القشرة كمـا أُجري التحليل الكيميائي للعصير، خضعت البيانات المتحصل عليها للتحليل الإحصائي و أظهرت النتائج مـا يأتي: بلغ أعلى معدل لوزن الثمرة 3.527 غ في الطراز خضاري، في حين تراوحت نسبة العصير في الثمرة بين 5.49 – 2.63 % أما وزن القشرة/الثمرة فقد تراوح بين (15% في الطراز طائفي و بـين 9.35 % فـي الطراز صيني) في حين كان سمك القشرة بين 5.1 – 2.4 مم. كما تميز الرمان السوقطري بأنه مـستديم الخضرة و إزهاره مستمر على مدار العام . تفوق الطراز خازمي في عدد الثمار/شجرة بمعدل 7.246 ثمرة، و بلغ أعلى معدل لقيمة الــ .S.S.T و فيتامين C 57.18 % و 12.11 مع على التوالي في الطراز صيني، و كان أعلى معدل للأحماض العضوية في هذه الطرز قد بلغ 54.0 % و ذلك في الطراز طائفي.
Study was conducted in five locations as the important areas for pomegranate cultivation and production in Yemen, during the period (15/1– 15/8/2004). Eight accessions of local pomegranate were used in this study: Taefi, Orkobi, Mellies–Hada, Khazemy, Sommaty, Kodary, Chiny and Mellies– Raudha in addition to the wild pomegranate type (Socotria). The morphological characters were determined for leaves, flowers,fruits and seeds. The chemical analysis for juice was also assessed. Maximum rate for fruit weight was 527.3 gm for Kodary accession, whereas fruit Juic varied between 49.5–63.2%, while peel / fruit was varied between15% in Taefi and 35.9 % in Chiny, whereas the peel thickness varied between 1.5–4.2 mm. The Scotria was found to be evergreen, and flowers around the year. Kazemy accession gave higher fruits number/tree with rate 246.7. The greatest rate of T.S.S and Vitamin C were 18.57% and 11.12 mg respectively for Chiny accession, and the highest content of organic acids in these accessions was 0.54 % for Taefi.

The aim of study was to compare the physicochemical and morphological properties of
Five pomegranate cultivars grown in different region of latakia.
Properties included: fruit fresh weight,number of arils per fruit, peel weight, soluble solids
(TS
S), titratable acidity (TA)vitamin, reducing sugar .
Fruit weight ranged from(336.8 -484.77 g), peel weight of the fruit was recorded from
93,84 to 127,85g, juice weight was( 69,33-151,66 g) and reducing sugars ranged between
(3.64 -12.4 %). total soluble solid ranged from( 14.5- 16.5) % and titratable acidity ranged
between( 0.358- 1.321%)in pomegranate juices.vitamin C content also ranged between
11.5- 14.5 mg\100 ml).
Sublethal toxicity studies were conducted with a rotifera (Brachionus
calyciflorus) to determine the No observed effect concentrations (NOECs) of a
different eight toxic substances based on the protein mass reduction. Protein
mass (with moleculer
weight 43KDa - 67KDa) was quantified using
electrophoresis method. Quantitation of protein concentrations demonstrated
that toxicant stress reduced protein concentrations. The NOECs-43KDa and
NOECs - 67KDa were reported. Since in vivo protein cocentrations can be
assessed in a short time, these results can be obtained in only a few hours,
which is substantially less than traditional whole animal reproductive tests.
NOECs - NOECs - 43KDa test were generally more sensitive end points than
NOECs - NOECs-67KDa test and more sensitive than standard whole animal
toxicity tests for only four toxicants.
Random Amplified Polymorphic DNA (RAPD) was used to evaluate genetic
diversity among 11 Yemeny pomegranate types. Samples were collected in 2004
from three main regions: east, middle and north of the country (Rada, Hada
and Saada). PCR amplificati
on of pomogranate DNA with 30 random primers
generated 1013 bands, 118 of them were polymorphic 11.5%. Results showed
that the genetic diversity within the tested types was limited. Similarity values
ranged between 59 –96 % with a mean of 79 %. Statistical analysis showed
that the types can be divided into two clusters: cluster 1 with Orkobi and
Mellies types found in the Hada region; cluster 2 includes nine types belonging
to the Saada and Radaa regions .High similarity (90–96%) was obtained with
Khazemy, Liessy 1, Liessy 2, Taefi, Ahmer and Balady types. Whereas, some
types could be considerd as separate cultivars due to their high genetic
diversity such as, Orkoby and Mellies (Hada region) in addition to Bohssom,
Sommaty and Liessy 3 in the Saada region.
Some quality indicators were studied , such as lactic acid bacteria and
probiotic count during and after the preservation period .
The study was excuted in Latakia governorate during the period (2014-2015). In this
study, it has been used three cultivars of Eriobotrya japonica which were Seedawi,
Morocan and Municipal). Onfigurable characterization, the average fruit weight ca
lculation
and the average number of seeds have been done of the fruit. Some chemical analysis were
also conducted of the juice. The data has been statistical analyzed and the results showed
that the earliest cultivar in maturity was Municipal. The highest rate of average fruit s
weight was (53.40g) in Morocan cultivar. And the fruits shapes were between the oval
shape in the Morocan and Seedawi cultivar, and circular shape in the Municipal cultivar.
The Morocan and Seedawi cultivars have the supremacy in production quantity(34.67-34
kg/tree) respectively at the Municipal. The highest proportion was in vitamin C, the acidity
and sugars were (0.977,1.073,15.20 %) respectively in municipal cultivar.
