Ask ChatGPT about the research

Despite being one of the reasons of production decline, salinity is still a tool to improve production quality in some hybrids. this research was conducted at the Faculty of Agriculture, University of Damascus during 2012 season. A salt stress was applied on two tomato hybrids, Bonaparte and Marmara by increasing the value of the electrical conductivity of irrigating water from 4 to 13 ds / m, at the stage of the third true leaf to the end of growth of the two tomato plants. Results indicated that salt stress led to a reduction in the fruit weight of both hybrids but it helped in improving some chemical and physical characteristics relating to fruit quality, such as increasing the fruit content of soluble solids in both hybrids. Salt stress did not affect the lycopene content of fruits in Bonapart, but it was increased by 2 folds inMarmara. Some fruit color indices (a* and b*) were greater in Bonaparte while L* indice was higher in Marmara. However, the color indices of fruits were not affected by salinity in both hybrids studied.

Research summary
تناولت الدراسة تأثير الإجهاد الملحي على بعض الصفات النوعية لثمار هجينين من البندورة (Marmara و Bonaparte) من خلال زيادة الناقلية الكهربائية لمياه الري من 4 إلى 13 ds/m. أظهرت النتائج أن الإجهاد الملحي أدى إلى انخفاض وزن الثمار في كلا الهجينين، ولكنه ساهم في تحسين بعض الصفات الكيميائية والفيزيائية المتعلقة بجودة الثمار. زادت الملوحة من محتوى المواد الصلبة الذائبة في الثمار لكلا الهجينين، ولم تؤثر على محتوى الليكوبين في Bonaparte بينما زاد بمقدار مرتين في Marmara. تفوق الهجين Bonaparte في مؤشري اللون *a و *b، بينما تفوق Marmara في المؤشر *L. لم يؤثر الإجهاد الملحي بشكل معنوي على مؤشرات اللون في كلا الهجينين.
Critical review
دراسة نقدية: الدراسة قدمت معلومات قيمة حول تأثير الإجهاد الملحي على جودة ثمار البندورة، ولكن هناك بعض النقاط التي يمكن تحسينها. على سبيل المثال، كان من الأفضل توسيع نطاق الدراسة لتشمل هجن أخرى من البندورة لمعرفة ما إذا كانت النتائج متسقة عبر أنواع مختلفة. كما أن الدراسة لم تتناول تأثير الملوحة على الجوانب الاقتصادية للإنتاج الزراعي، وهو جانب مهم يجب مراعاته. بالإضافة إلى ذلك، كان من الممكن تقديم تحليل أعمق للآليات البيوكيميائية التي تؤدي إلى التغيرات الملحوظة في جودة الثمار تحت تأثير الإجهاد الملحي.

A salt stress was applied from 3rd leaf stage until the maturation on three tomato cultivars (Marmara, Levovil and Picolino). The salt stress was achieved by increasing the solution EC from 3 (control) to 6.7 dS/m for, Na and Na+Ca treatments, resp ectively. The stress induced a significant increase in vitamin C of Marmara and Levovil fruit content (20.94 and 23.03 mg/100g) as compared to the control (16.62 and 19.43 mg/100g, respectively). The titratable acidity was increased significantly (17%) only in Marmara and Picolino. The fruit content of fructose was increased in Levovil and Picolino by 1.4 and 1.7 folds, respectively, as compared to control (11.13 and 18.8g/kg, respectively). While the content of N in Levovil and Picolino was decreased, under stress, by 33 and 58% as compared to the control (0.12 and 0.19%), respectively, the P content was increased. The salt stress decreased the K content in Levovil and Picolino to reach to 0.22 and 0.26% as compared to control (0.27 and 0.29%), respectively. The calcium addition modified the stress impact. A significant increase, was registered in Ca content under stress in Marmara andPicolino as compared to control, while the calcium addition did have any effect on.
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.
In this study, the effect of different concentrations of sodium chloride (NaCl) (0, 50, 100, 150 mM) on some physiological characteristics and some growth indicators of SO4 grape rootstock propagated in vitro was studied at the laboratories of Gen eral Commission for Scientific Agricultural Research (GCSAR), Damascus/Syria. Results indicated that the increase of NaCl concentration up to 100 mM in culture medium led to reduce the growth indicators (survival plants, average of the plant length and average number of buds) with significant differences when compared with the control plants after 4 weeks from culturing on multiplication media, while treatment with 150 mM of sodium chloride led to death of all plants. Using the concentrations 50 and 100 mM of NaCl also caused decreasing the total chlorophyll content in the leaves.
The experiment was carried out during spring season 2016 to study the effect of foliar spraying treatment with Tecamin Flower 2.5 ml/L in comparison with distilled water, on growth of three hybrids of tomatoes at two different levels of irrigation (100 and 50 % of field capacity). Three sprays were conducted started from flowering with two weeks’ interval. The results showed that ‘Finenss’ hybrid had significant differences in plant height, branches per plant and leaves number per plant. ‘Hadeer’ hybrid had superiority in dry matter ratio and content of chlorophyll in leaves. Reducing the level of irrigation resulted in a significant decrease in plant height, total branches number, versus an increase in the leaves number per plant, total leaves area and the percentage of dry matter. The results showed that the treatment with Tecamin flower led to a significant increase in all indicators studied. The interaction treatments shoed that Hadeer hybrid irrigated in level 50 % and spraying of nutrient solution (Tecamin flower) had a significant increase in dry matter ratio and chlorophyll content in leaves. While the hybrid Finenss which irrigated in level 100 % with nutrient solution (Tecamin flower) had a significant increase in leaves number per plant and total leaves area.
The research was conducted at the Maize Researches Department, General Commission for Scientific Agriculture Researches (G.C.S.A.R.) Damascus, Syria during the summer growing seasons of 2010, 2011 and 2012. Treatments were arranged in a Randomized Complete Blocks Design with three replications. The research aimed to evaluate genetic parameters for some traits like days to 50% silking, plant and ear height, ear length, ear diameter, number of rows per ear, number of kernels per row, 100 kernel weight and grain yield per plant using generations means analysis of two maize hybrids (IL.292-06 × IL.565-06, IL.459-06 × IL.362-06) to detect epistasis and estimates of mean effect [m], additive [d], dominance [h], additive × additive [i], additive × dominance [j] and dominance × dominance [l] parameters. Results showed that the additive - dominance model was adequate to demonstrate the genetic variation and its importance in the inheritance of most studied traits. Nonallelic gene interaction was operating in the control of genetic variation in most studied traits. The signs of [h] and [l] were opposite in most studied traits for the two crosses. Also, the inheritance of all studied traits was controlled by additive and non-additive genetic effects, but dominance gene effects play the major role in controlling the genetic variation of the most studied traits, suggesting that the improvement of those characters need intensive selection through later generations. The phenotypic variations were greater than genotypic variations for all studied traits in the two crosses, indicating greater influence of environment in the expression of these traits. Highly significant heterosis relative to mid and better parents, respectively was found for all characters, and this accompanied with inbreeding depression for all traits. Narrow sense heritability and genetic advance were low in most of the traits due to the dominance of non-additive gene action in controlling the genetic variation of the most studied traits and this predict low to medium values of genetic advance through selection process.
