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, length 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.

Research summary
تتناول هذه الدراسة غربلة تسع عشرة سلالة منتخبة محلياً من البطاطا لمدى تحملها للإجهاد المائي باستخدام تقنية الزراعة في الزجاج. تم تطبيق الإجهاد المائي بإضافة 4% من السوربيتول إلى وسط النمو، وتم قياس عدة معايير للنمو مثل طول النبات وقطره، المساحة الورقية، عدد الجذور وطولها وقطرها، والوزن الرطب والجاف للنباتات. أظهرت النتائج اختلاف استجابة السلالات للإجهاد المائي، حيث تم تقسيم السلالات إلى ثلاث مجموعات: المتحملة للإجهاد، متوسطة التحمل، والحساسة للإجهاد. أظهرت الدراسة أن تقنية الزراعة في الزجاج يمكن أن تكون أداة فعالة لتقييم وغربلة سلالات البطاطا من حيث تحملها للإجهاد المائي، مما يسهم في تحسين برامج تربية البطاطا.
Critical review
دراسة نقدية: تقدم هذه الدراسة مساهمة قيمة في مجال زراعة البطاطا، حيث تقدم طريقة فعالة لتقييم تحمل السلالات للإجهاد المائي باستخدام تقنية الزراعة في الزجاج. ومع ذلك، يمكن تحسين الدراسة من خلال تضمين مزيد من التفاصيل حول الظروف البيئية المحيطة بالتجارب، وكذلك دراسة تأثير الإجهاد المائي على المدى الطويل. بالإضافة إلى ذلك، قد يكون من المفيد مقارنة النتائج مع دراسات ميدانية لتأكيد فعالية التقنية المستخدمة في ظروف الحقل.

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 solutio n (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.
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.
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.
A field experiment was carried out at Abi Jarash farm at the Faculty of Agriculture at Damascus University during the 2011-2012 agricultural season in order to study the effect of seed hardening and supplementary irrigation in improving the tolerance of faba bean (vicia faba L.) varieties to water stress.
This study was carried out at the Faculty of Agriculture, Damascus University, and ACSAD during the year 2001 – 2002 in order to assess the genetic variability of twenty wheat genotypes for osmotic stress tolerance by using PEG-6000 as a water str ess induced tool. This trial aimed to develop a semi-natural rapid and effective screening technique in which the optimum induction as well as lethal levels of osmotic stress are well defined . The results revealed that the treatments –0.4 MPa and –1.5 MPa were the optimum induction and lethal levels of osmotic stress, respectively.
