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.

Research summary
تتناول هذه الدراسة تحليل وتقييم الصفات النوعية والكيميائية لأهم طرز الرمان المزروعة في اليمن. أجريت الدراسة في خمسة مواقع رئيسية لزراعة الرمان خلال الفترة من 15 يناير إلى 15 أغسطس 2004. تم استخدام ثمانية طرز من الرمان المحلي في هذه الدراسة وهي: طائفي، عرقبي، مليس الحداء، خازمي، صماطي، خضاري، صيني، ومليس الروضة، بالإضافة إلى نوع الرمان البري السوقطري. تم توصيف الأوراق والأزهار والثمار والبذور، كما تم إجراء تحليل كيميائي للعصير. أظهرت النتائج أن الطراز خضاري حقق أعلى معدل لوزن الثمرة (527.3 غرام)، بينما تراوحت نسبة العصير في الثمار بين 49.5% و63.2%. كما أظهرت النتائج أن الطراز خازمي أعطى أعلى عدد من الثمار لكل شجرة (246.7 ثمرة)، بينما كان أعلى معدل لفيتامين C في الطراز الصيني (11.12 ملغ/100 مل عصير). بالإضافة إلى ذلك، تميز الرمان السوقطري بأنه مستديم الخضرة ويزهر على مدار العام.
Critical review
دراسة نقدية: تعتبر هذه الدراسة شاملة ومفصلة حيث تناولت العديد من الجوانب المهمة لزراعة وإنتاج الرمان في اليمن. ومع ذلك، يمكن الإشارة إلى بعض النقاط التي قد تعزز من جودة البحث. أولاً، كان من الممكن توسيع نطاق الدراسة ليشمل المزيد من المواقع والطرز المختلفة للرمان لتحسين تمثيل العينة. ثانياً، لم يتم التطرق بشكل كافٍ إلى تأثير العوامل البيئية والمناخية على النتائج، وهو ما يمكن أن يكون له تأثير كبير على إنتاجية وجودة الثمار. ثالثاً، كان من الممكن استخدام تقنيات تحليلية أكثر تقدماً للحصول على نتائج أكثر دقة وشمولية. وأخيراً، كان من المفيد تضمين توصيات عملية للمزارعين بناءً على النتائج المستخلصة من الدراسة.

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.
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.
