Effect of different doses of Gamma radiation (٢٠٠, ٤٠٠, and ٨٠٠ Rad) on rooting of different clones of poplar was investigated. Results showed that the dose of ٢٠٠ rad had a great effect on rooting. Percentage and the root length. On the other hand, the dose of ٨٠٠ rad had a negative effect on rooting. The negative effect could be to the breakdown of the auxins in the cuttings. It had been noticed that there was similarity among means of root weights with regard to clones of Populus alba cv. buchovina. As for as the doses were concened, these were no signix ficant diffecsnses among maens of that ments.

Research summary
تأثير جرعات مختلفة من الإشعاع الجاما (200، 400، و800 راد) على تجذير بعض أصناف الحور تم التحقيق فيه. أظهرت النتائج أن جرعة 200 راد كان لها تأثير كبير على التجذير، حيث زادت نسبة وطول الجذور. من ناحية أخرى، كانت جرعة 800 راد لها تأثير سلبي على التجذير، وقد يكون السبب في ذلك هو تكسير الأوكسينات في القصاصات. لوحظ تشابه بين متوسطات أوزان الجذور بالنسبة لأصناف Populus alba cv. buchovina. فيما يتعلق بالجرعات، لم تكن هناك فروق ذات دلالة إحصائية بين متوسطات تلك الأوزان.
Critical review
دراسة نقدية: على الرغم من أن الدراسة تقدم رؤى قيمة حول تأثير جرعات الإشعاع الجاما على تجذير أصناف الحور، إلا أن هناك بعض النقاط التي يمكن تحسينها. أولاً، لم يتم توضيح الآلية البيولوجية بشكل كافٍ لتفسير تأثير الجرعات المختلفة على تجذير القصاصات. ثانياً، كان من الممكن توسيع نطاق الدراسة لتشمل أنواعًا أخرى من النباتات للحصول على نتائج أكثر شمولية. وأخيراً، كان من الأفضل تضمين تحليل إحصائي أكثر تفصيلاً لتوضيح الفروق بين الجرعات بشكل أدق.
Questions related to the research
  1. ما هي الجرعات المختلفة من الإشعاع الجاما التي تم استخدامها في الدراسة؟

    تم استخدام جرعات 200، 400، و800 راد من الإشعاع الجاما.

  2. ما هو تأثير جرعة 200 راد على تجذير القصاصات؟

    جرعة 200 راد كان لها تأثير كبير على التجذير، حيث زادت نسبة وطول الجذور.

  3. لماذا كان لجرعة 800 راد تأثير سلبي على التجذير؟

    قد يكون السبب في التأثير السلبي هو تكسير الأوكسينات في القصاصات.

  4. هل كانت هناك فروق ذات دلالة إحصائية بين متوسطات أوزان الجذور بالنسبة للجرعات المختلفة؟

    لم تكن هناك فروق ذات دلالة إحصائية بين متوسطات أوزان الجذور بالنسبة للجرعات المختلفة.

This experiment was carried out to study the effect of increasing gamma radiation doses (up to 24 GY) on the eggs of Callosobruchus maculatus, at different ages, to determine their effect on egg hatching rate, and other biological traits of the em erging adults from eggs treated with sub – lethal doses. It has been noticed that the low gamma radiation doses killed most of the one –day old eggs before hatching, and no adult insect could emerge from hatching those eggs, and the dose of 12GY caused the same effect, but on two day-old eggs. when eggs were at the age of 3, 4, and 5 days, gamma radiation didn’t have influenced on the embryo development, but demise percentage, increased after hatching. The percentage of emerged adults was only 1.8% for the eggs treated with 16 GY gamma radiation.
This research was conducted at AlTieba Research Station, General Commission for Scientific Agricultural Research (GCSAR) in 2012 and 2013 seasons, to study the effect of different doses of gamma rays on growth and productivity of local garlic Alli um sativum L. cultivar “Yabroudi” in Syria. Cloves were exposed to four different doses of gamma rays of 60Co source 1, 2.5 ,5 ,10 ) Gray). Randomized Complete Block Design (RCBD) was used .The results showed the surviving plants after 60 days of planting declined with the increase of dose levels. The percentage of dead plants at the doses (2.5, 5 Gray) was 50 and 54 %, respectively. Also, it was possible to obtain a larger number of viable mutations. Therefore, they could be considered as close as to LD50. The dose (10 Gray) had a negative effect on the length of the cloves’ germination period, leading to the death of all the plants after 60 days of planting, this could be considered lethal dose (LD100). The response of the local garlic cultivar Yabroudi to the low-dose (1 Gray) of gamma ray was higher comparing with other doses. This is due to the positive effect of this dose (Stimulus) on the vegetative growth that was reflected on the productivity indicators. The productivity reached (4.50 kg/m2), which was significantly superior to the control (2.91 kg/ m2) and the two doses (2.5, 5 Gray), respectively (2.26, 1.60 kg/ m2).
In this paper, we study the Gamma function, and the representation of a complex variable, using either sequential or appropriate integration ,and its application in solving certain types of integral equations , and their relationship to the Riemann- Zeta function, and used to solve the contour integration ,and to find the integration of Hankel’s contour integral according to Bessel function for integer n.
This work was conducted to study the effect of two levels (50 and 75%) of pruning on flowering (number of clusters, number of flowers, diameter of flowers, flower-stem length) of three cultivars (Emile Mouillère - Nikko Blue - Pia) of Hydrangea ma crophylla. Pruning was done on the shrubs of four years old in addition to a control without pruning. Results indicated that there were differences among cultivars in response to the proportion of pruning. Emile Mouillère, a cultivar with white flowers, the results showed an increase in the proportion of pruning was associated with a reduction the number of fully developed inflorescences per plant compared to control. For Nikko Blue, a cultivar with blue flowers, the results showed that level (75%) was the best in all studied indicators while for Pia, a cultivar with deep pink flowers, the results showed that pruning with 50% level was the best in all productivity indicators.
Orange fruits are characterized at harvesting with physical and sensory properties determine consumer acceptance and in order to identify these characteristics and vulnerability storage and irradiation conditions, Valancia orange fruits were subje cted to gamma irradiation at doses of 0.0, 0.5, 1.0, and 1.5 kGy using gamma 60Co irradiator facility. Fruits were kept in a refrigerator for 18 weeks. Results indicated that physical and sensory properties of Valencia orange fruits were affected by storage time and irradiation. The overall color differences were increased and the firmness of fruits and skin were decreased. The used doses of gamma irradiation increased the overall color differences of fruit skin. Whereas the fruit firmness, and the sensory properties (aroma, color, test and firmness) of irradiated Valencia orange fruits were decreased.
