This present study was conducted to develop a detailed in vitro propagation system for the medicinal shrub Capparis spinosa L. Single nodes with one bud and a small part of stem of 1-1.5 cm long were used as initial explants which were collected from a shrubs grown under field conditions at Damascus suburb., (Doumar). Explants were surface-disinfected by 70% Ethanol for 1 min., followed by immersion in Sodium Hypochlorite or HgCl2 for different periods and concentrations with 1 drop of Tween 20 for 100 ml disinfectant solution, where after, they were placed onto MS basal medium containing a combination of growth regulators at different concentrations (BA at 4.44 or 8.88 μM) each with IBA 0.49 μM. Cultures were incubated in the growth room at 23±1 c and light intensity of 3000 lux at the cultures level. Multiplication rate of 25.17-fold from one explant was achieved every 4 weeks on the optimal MS medium (MS+8.88μM BA+0.49μM IBA). The described method has potential to produce large numbers of plantlets within a short period of time to expand its cultivation for medicinal uses.

Research summary
تتناول هذه الدراسة تطوير نظام تفصيلي للإكثار في المختبر لشجيرة القبار الطبية (Capparis spinosa L.) باستخدام تقنيات زراعة الأنسجة. تم استخدام عقدة واحدة مع برعم واحد وجزء صغير من الساق بطول 1-1.5 سم كعينات أولية، والتي تم جمعها من شجيرات نمت في ظروف الحقل في ضواحي دمشق. تم تطهير العينات السطحية باستخدام الإيثانول بنسبة 70% لمدة دقيقة واحدة، تلاها غمرها في هيبوكلوريت الصوديوم أو HgCl2 لفترات وتركيزات مختلفة مع قطرة واحدة من توين 20 لكل 100 مل من محلول المطهر، ثم وضعت على وسط MS الأساسي المحتوي على مجموعة من منظمات النمو بتركيزات مختلفة (BA بتركيز 4.44 أو 8.88 ميكرومول) مع IBA بتركيز 0.49 ميكرومول. تم تحضين الثقافات في غرفة النمو عند درجة حرارة 23±1 درجة مئوية وشدة ضوء 3000 لوكس عند مستوى الثقافات. تم تحقيق معدل تكاثر يبلغ 25.17 ضعف من عينة واحدة كل 4 أسابيع على وسط MS الأمثل (MS+8.88µM BA+0.49µM IBA). تمتلك الطريقة الموصوفة القدرة على إنتاج أعداد كبيرة من الشتلات في فترة زمنية قصيرة لتوسيع زراعتها للاستخدامات الطبية.
Critical review
دراسة نقدية: تعتبر هذه الدراسة خطوة مهمة نحو تطوير طرق فعالة للإكثار في المختبر لشجيرة القبار، والتي لها استخدامات طبية واسعة. ومع ذلك، يمكن أن تكون هناك بعض التحسينات الممكنة. على سبيل المثال، يمكن أن تكون الدراسة أكثر شمولية إذا تم تضمين تحليل أكثر تفصيلاً لتأثيرات منظمات النمو المختلفة على مراحل النمو المختلفة للنبات. بالإضافة إلى ذلك، يمكن أن تكون هناك حاجة إلى تجارب ميدانية لتقييم أداء الشتلات المنتجة في ظروف الحقل الفعلية. كما أن الدراسة لم تتناول بشكل كافٍ الجوانب الاقتصادية لتطبيق هذه التقنية على نطاق واسع، وهو ما يمكن أن يكون مفيدًا للمزارعين والمستثمرين.

Research was carried out in (24) locations where two subspecies Capparis spinosa were recorded in Syria . The subspecie C. spinosa subsp. rupestris was found in seven locations, mostly in the southern region of the environment, while he found the S yrian C. spinosa subsp. spinosa in seventeen of the study sites in Syria. Chemical analysis showed that, the soils of all location were not salty and pH ranged between (6.9-8.4), Soils texture was clayey and clay loam in most locations. According dependant on equation of Emberger, it was found that distribution of subspecies Capparis spinosa were located in a wide range from bioclimatic very dry to semi- humid zone, through with dry, semi-dry, and Hyper humid zones.
In this study, we used plant tissue culture techniques for micropropagation of the endangered Red Doumani cultivar. The explants which were the apex tips and axillary buds (0.5-1 cm) have been cultured on the free of hormones initial medium WPM (W oody plant medium), then moved to the micropropagation media. The results showed that the medium containing 4.44 mM BA + 0.58 mM IAA had the best effect on number of new shoots formed (2.6) and the growth started after 9.22 days, the best elongation was on the medium supplemented with 4.6 mM KIN + 0.58 mM IAA and the rate of multiplication reached 5.15 shoots.
Samples of Capparis spinosa plant were collected from 6 sites in Aleppo and Lattakia provinces. The genetic variations were studied using the AFLP technique in order to determine the genotypes of the studied types using 3 primers, which showed ampl ification. Statistical analyses were conducted using the dissimilarity coefficient and genetic diversity coefficient. The A.C.P. and the statistical -F were calculated, and the similarity dendrogram was constructed. The results showed the following: The presence of a certain number of specific alleles (descriminates) for each province. The presence of genetic and reproductive isolation deterrent to gene flow between the two provinces. The heterozygoty average was a little higher in Lattakia (0.486) than in Aleppo (0.481). The mean of genetic diversity coefficient of primers and individuals was a little higher in Aleppo (0.677) than in Lattakia (0.653). The population mean was very close: (0.759) in Aleppo and (0.760) in Lattakia. This may be explained on the basis of silent and specific alleles due to deletion mutations, different selective effects as well as the reproduction system in the two cities. The greatest genetic distance in Aleppo was (0.381) noted between (Al Dahea and Al Shekh saaed), and in Lattakia (0.38) noted between (Al Amroniah and Jabla). However, the greatest genetic similarity in Aleppo was (0.637) noted between (Al Shekh Saaed and Turkman Bareh), and in Lattakia (0.675) noted between (Wata Deirzenon and Jabla). The variation between these values was graduated. The study of statistical –F showed the effect of the similarity factor in some populations. This was more significant in Aleppo than in Lattakia, which indicates that the reproduction system is more closed in Aleppo, and this refers as well to inbreeding or self pollination which showed high genetic variations in these populations when compared with Lattakia. The results of this study helped in determining primers that can be used as molecular markers in a breeding program for Capparis spinosa as a medicinal plant. This technique showed high efficiency in studying the similarity relationships between these two cities.
Flower buds of capers were processed by some common methods as pickling, salting, and other uncommon like freezing with and without blanching and canning. The results showed that there was no microbiological growth in all methods since the fourth month of storage. Best growth for lactobacillus bacteria was in 5% brine (8.2 × 106) and then in 8% brine (1.2 × 106)CFU.g-1 . while there wasn’t any growth of this bacteria by using other methods like using high concentration of salt 23%. On other hand, the results showed that this bacteria existed in small account (1.4 × 102) and (1.1 × 102) CFU.g-1 after a week in brine 16% and the freezed sample respectively. There was no statistical difference between the two storage solutions as there wasn̓ t any microbiological growth in both of them through 8 months.
