This study was conducted at Abo Jarash farm, Faculty of Agriculture, Damascus University In order to determine the response of three local varieties of potato (Sponta, Draja, Diamont) to salinity stress with different concentration of NaCl solution (0,50, 100, 150, 200 mM). The results indicated that the existence of a inverse correlation between increased concentrations of salts in the solution and the rate of plant height, leaf area, and the percentage of leaf dry weight, and the proportion K+/ Na+., and the productivity was declined with a proportional rate 22< 32, and 48% for the varieties of Sponta, Draja, Diamont, respectively. Results indicated the existence of reverse relationship between increasing salt concentration in the medium and plant height, Leaf area, dry weight of the leaves and K+/Na+ ration in addition to the decline in the productivity of studied varieties. The results also showed variations in the extent of tolerance between studied varieties to salinity stress where Sponta was the most tolerant, followed by Draja and Diamont was the less tolerant and this was reflected in terms of higher germination and increasing the mean of plant height, Leaf area and dry weight of plant.

Research summary
تتناول الدراسة استجابة ثلاثة أصناف من البطاطا (سبونتا، دراجا، وديامونت) للإجهاد الملحي بتراكيز مختلفة من محلول NaCl (0، 50، 100، 150، 200 mM). أظهرت النتائج وجود علاقة عكسية بين زيادة تركيز الأملاح وطول النبات، المساحة الورقية، الوزن الجاف للأوراق، ونسبة K+/Na+. كان صنف سبونتا الأكثر تحملًا للإجهاد الملحي، يليه دراجا، ثم ديامونت الذي كان الأقل تحملًا. تم تنفيذ التجربة في مزرعة أبي جرش التابعة لكلية الزراعة بدمشق خلال الموسم الزراعي 2009-2010. تم قياس عدة مؤشرات مثل المساحة الورقية، الوزن الجاف للأوراق، طول النبات، محتوى الماء النسبي، ومحتوى الأوراق من شوارد الصوديوم والبوتاسيوم. أظهرت النتائج أن زيادة تركيز الأملاح تؤدي إلى انخفاض في جميع المؤشرات المدروسة، مع تفاوت في درجة التحمل بين الأصناف الثلاثة. توصي الدراسة بانتخاب الأصناف الأكثر تحملًا للإجهاد الملحي لاستثمارها في الزراعة في المناطق المتملحة.
Critical review
دراسة نقدية: تعد هذه الدراسة مهمة لفهم تأثير الإجهاد الملحي على نمو وتطور البطاطا، خاصة في المناطق الجافة والمتملحة. ومع ذلك، يمكن توجيه بعض الانتقادات البناءة لتحسين البحث. أولاً، كان من الأفضل تضمين أصناف بطاطا أخرى لتوسيع نطاق النتائج. ثانيًا، يمكن تحسين دقة النتائج باستخدام تقنيات تحليلية أكثر تطورًا مثل التحليل الجيني لتحديد الجينات المسؤولة عن تحمل الملوحة. ثالثًا، لم يتم التطرق بشكل كافٍ إلى تأثير الملوحة على جودة الدرنات المنتجة، وهو جانب مهم يجب مراعاته في الدراسات المستقبلية. أخيرًا، يمكن تحسين تصميم التجربة بإضافة مكررات أكثر لضمان دقة النتائج وتقليل التباين.

Marfona cultivar were chemical mutagen using 20, 30 and 40 mM of Ethyl Methane Sulphonate (EMS) for 2, 3, 4 hrs in 2013. was conducted to improve potato (Solanum tuberosum L.) tolerance to salinity. Plants Marfona mutagen from M5 and unmutagen were cultured with Spunta and Falouka Cvs in 2015. Plants were later subjected to another selection pressure, by irrigating them using water containing Nacl between 0-200 mM The results showed that the gradual increase in Nacl concentrations caused a significant gradual decreases in most vegetative, yield and its component characteristics. Mutant plants varied with unmutant for Marfona, Spunta and Falouka in plant height varied from 68 to 41 cm and number leaves varied from 21 to 12 leaf. and stem diameter varied from 1.349 to 0.370 cm and leaf area varied from 235 to 84 cm2. However, produced tubers number varied from 9.3 to 2.8 and weight them from 740 to 155 grams and tuber weight from 75.2 to 24.6 grams. The results also showed variations in the extent of tolerance between studied treatments to salinity stress where 4T3P2 treatment was the most tolerant.
Nineteen locally selected potato lines were screened for water stress tolerance by measuring the growth parameters in vitro. The stress was achieved by adding 4% of sorbitol to the growth medium. Plant height and diameter, leaf area, number, lengt h and diameter of roots and plant fresh and dry weight were measured. The results showed a difference in the response of the studied lines to water stress, cluster analysis, based on the sum of all growth parameters relative values of the lines showed that the lines were divided into three groups according to water stress tolerance: The tolerant group, the moderate tolerant group and the sensitive group. The results indicated the possibility to use the in vitro method to screen the potato lines for water stress tolerance.
Several laboratory experiments were conducted to evaluate the response of ten ACSAD durum and bread wheat landraces to salinity stress tolerance at seedling stage. The salinity induction response technique was applied to assess the genetic variabi lity, and the effect of induction nature in improving the tolerance to lethal levels of some abiotic stresses (drought and salinity). The applied screening tool was rapid and efficient in assessing the genetic variability for the response of studied durum and bread wheat landraces to salinity stress tolerance.
Experiments were conducted to study effect of radiation and salt levels on plant regeneration from callus for two cultivars of potato i.e. Riviera and Burren, under in vitro condition. Results showed that the efficiency of radiation in induced reg eneration from callus in Riviera cultivar at salt level of (10 dS m-1) and Burren cultivar at salt levels (8, 12 dS m-1). For the purpose of making sure inheritance of salinity tolerant, mutant clones (plants induced from salt tolerant calli, which planted at salt levels of 8, 10, 12 dS m-1 and plants induced from non salt tolerant calli, which planted at salt level of 6 dS m-1) and their parental cultivars (Riviera and Burren) by exposing to salt stress conditions and comparing them with control (6 dS m-1). Results revealed that the lowest percentage of reduction in plant height, number of nods per plant and tuberization were observed in salt tolerant mutants. Plant height and number of nodes/plant can be considered as selective morphological markers for in vitro salt tolerance .
The research was conducted on some olive varieties known as Alsourani- Aldan- Mahazm Abu Satel- Alglet- Alnepali, in the aim of comparing their tolerance against the stress of salinity (sodium chloride) through some morphological and physiological traits. Different concentrations of salt as well as to the control (fresh water) were used in this experiment.
