Research summary
تهدف هذه الدراسة إلى تقييم تأثير أربعة أنواع من بكتيريا الرايزوبكتيريا المحفزة لنمو النبات (PGPR) وهي: Azotobacter chroococcum، Rhizobium leguminosarum، Bacillus megaterium، وFrateuria aurantia على نمو وإنتاجية نبات الفليفلة، وكذلك الحد من تأثير فيروس موزاييك الخيار (CMV). تم تنفيذ التجربة في بيت بلاستيكي في طرطوس خلال موسم 2016/2017. أظهرت النتائج أن التلقيح بالبكتيريا، سواء كان فردياً أو مختلطاً، أدى إلى زيادة معنوية في جميع المعايير المدروسة مقارنة بالشاهد غير الملقح. كما قلل التلقيح من تأثير العدوى بفيروس موزاييك الخيار. تفوق التلقيح المختلط بالأنواع الأربعة من البكتيريا على التلقيح الفردي، حيث بلغ ارتفاع النبات 125.4 سم ووزن الثمار 19.73 كغ/نبات. تشير الدراسة إلى أن استخدام مزيج من هذه البكتيريا يمكن أن يكون بديلاً آمناً وفعالاً لتحسين نمو وإنتاجية الفليفلة والحد من تأثير الفيروسات النباتية.
Critical review
دراسة نقدية: تقدم الدراسة مساهمة قيمة في مجال الزراعة الحيوية من خلال تسليط الضوء على دور بكتيريا الرايزوبكتيريا في تعزيز نمو النبات ومكافحة الفيروسات النباتية. ومع ذلك، يمكن تحسين الدراسة من خلال توسيع نطاق التجارب لتشمل مناطق مختلفة وظروف زراعية متنوعة لضمان تعميم النتائج. كما يمكن إضافة تحليل اقتصادي لتقييم تكلفة وفوائد استخدام هذه البكتيريا مقارنة بالأساليب التقليدية. بالإضافة إلى ذلك، يمكن تعزيز الدراسة بمزيد من التفاصيل حول الآليات البيوكيميائية التي تساهم في تعزيز النمو ومكافحة الفيروسات.

This study was conducted in the village of Almetrkyah located in the southern coastal plain of Lattakia city during 2014. In order to study the effect of Cucumber mosaic virus on growth and development of two varieties of peppers, hybrid ESTAR F1 H (sweet pepper) and Demer(spicy pepper). This study included eight treatments, four treatments for each variety. Plants were mechanically inoculated in three different stages, preflowering bloom, flowering andpost-flowering stages each beside its non-inoculated control. The result should that, the appearance of Cucumber mosaic virus symptoms on infected sweet hybrid, was within four days before its appearance on inoculated spicy variety,symptoms were leaf crinkle, leaf deformation, yellow patches and plant stunting. Inoculated plants showed reduction in number of leaves, number of branches and yield. Plants in pre flowering bloom stage were more effected by virus infection in both varieties. Meannumber of leaves per plant of ESTAR F1 H hybrid were 130 in pre flowering bloom stage compared with 170 leaf/plant in the control treatment. Mean number of branches per plant of ESTAR F1 H hybrid were 43,4 branch/plant in pre flowering bloom stage compared with 56,7branch/plant in the control treatment. Total pepper production per plant was 700,8g in infected plants in preflowering bloom stage compared with 1267,5g/plant in ESTAR F1 H hybrid control. Results of Demer variety take the same results of ESTAR F1 H hybrid. The effect of virus infection on pepper plants were reduced when inoculation were done during flowering stage and post-flowering stage, differences were significant between inoculated plants in both varieties.
This study aimed at studying the effect of using three species of bacteria (PGPR) Azotobacter chroococcum Bacillus megaterium and Frateuria aurantia in three inoculation manner ( seeds, shoots & seed+shoots) on suppressed the effect of Cucumber mo saic virus (CMV) on tomato plants (pots), Some growth parameters such as plant height, number of leaves on plant, foliage fresh weight, root fresh weight were observed after 60 days. The experiment carried out in 2016 in a greenhouse in Tartus.
This research aimsto study the effect of single and mixed infection of Potato Y Virus (PVY) and Cucumber mosaic virus(CMV) on the number of leaves, number of branches, plant height and stem circumference of tomato plants (cv.Elegro and Local). The ex periment was carried out in 2012 in a greenhouse in Tartous. Results show that the interactions in both varieties to virus infections are different. The mixed infections cause slight and weak effects compared to single infections. This is probably due to the antagonistic relationship between Potato Y virus and Cucumber mosaic virus and their effects on mean number of leaves, mean number of branches, mean height of plants, and mean stem circumference. Tomato plants' stems were (Elegro 106.42, 16.75, 103.58 cm, 4.84cm.; Local 94.42,15, 87.17 cm, 4.59 cm, respectively). Consequently, the timing of mixed infection playsarole in appearance, development and effect on other viruses.
This search aims to study the efficiency of using“Biotolerance” as a fertiliser; by a foliar spry on Pepper seedling. Four varieties were used (Marcony, California wander, Maroty-7 andRobber). The results showed that the treatment by the fertilizer resulted in an increase in growth thorough the plant length increasing.
Effect of Citrus trestiza virus (CTV) in Growth of Balady common orange and Satsuma trees grafted on sour orange Rootstock in Hraisoon during 2013 was studied. The results showed that of infection by CTV caused deformation of shaped leaves, boat or spoon-shaped leaves. The symptoms was greater in Satsuma from Balady common orange trees. Also leaf size average of Balady common orange trees reduced from 15.58 cm2 in healthy trees to 11.82 cm2 in infection trees as percentage 24.13, and from 19.64 cm2 in healthy Satsuma trees to 12.38 cm2 in infection trees as percentage 36.97. and length average of spring, summery and autumnal fresh foliages growths was reduced from 20.98 cm, 14.62 cm, 12.17cm in healthy Balady common orange trees to18.75cm, 12.52cm, 9.32 cm in infection trees respectively. Also it reduced from 18.78 cm, 14.56 cm, 10.06 cm in healthy Satsuma trees to 13.78 cm, 9.34 cm, 6.03 cm in infection trees respectively, the CTV had no significant effect on Trunk circumference in both varieties.
