Authors:Manar Ahmed Abbas, Ali Abdulridha Alsudani, Ashwaq Hussam Alhusani Pages: 1 - 6 Abstract: Laboratory experiments were conducted to determine the effectiveness of plant extracts of vitex and rosemary in red rust flour beetle Tribolium castaneum (Herbst) control. Results showed a significant effect of extracts oncentrations in the percentage of larval stage mortality . concentration of 5%, caused the highest mortality rates in the larval stage reached to 71.11, 76.66, 83.33 % insects / plate after 24, 48 and 72 hours, respectively. The mortality rates were equal for both concentrations 2.5 and 5%, which amounted to 90 % after 72 hours. Vitex plant extarct was significantly superior to the rosemary plant Rosmarinus officinalis in the mortality rates for all concentrations and periods post application in this study.

Authors:Hazim Sultan Safana, Majid Abdul-Hameed Ibrahim Ibrahim, Abdul-Kareem Muhammed Abd Pages: 7 - 18 Abstract: The research was conducted in a Plant Tissue Culture Laboratory, Agricultural Research Department, Ministry of Science and Technology, from December 10/1/2019 to December 30/1/2021, to study the effect of adding auxin NAA at concentrations (1, 2, and 3) mg L-1, and interaction with Chitosan at concentrations (10, 15, 20 and 25) mg L-1, to the culture media MS, to determine the optimal concentration in rooting the branches resulting from the multiplication of micro branches of the Kumquat plants (Citrus japonica), produced from in vivo development of the stem nodes. The results of the study showed that the planting of Kumquat branches in MS media supplemented with 2.0 mg L-1 NAA was a high significant response on rooting percentage (92.0%) and roots number (3.20 plant root-1), added 15 mg L-1 chitosan to the culture media prepared with 2.0 mg L-1 NAA was a significantly increased in same parameters (rooting percentage 80% and roots number 5.60).

Authors:Ahmed A. Hussein, Mahmoud M. Ahmed Pages: 19 - 28 Abstract: The study was conducted to choose the best way to store the fillets of common carp fish. Samples were divided into five treatments (T1 control treatment), (T2 glazing with saline solution 2%), (T3 glazing with acid solution 2%), (T4 coating with fish ex-tracted Gelatin), (T5 normal polyethylene- packaging). These five groups (treat-ments) have been stored in freezing conditions at four periods 2,4,6,8 weeks respectively. The qualitative and sensory properties of fish fillets were studied and the best results was belonging to T4 (gelatin coating treatment). The study included the process of gelatin extraction from fish waste as well. PubDate: 2022-03-21 Issue No:Vol. 9, No. 1 (2022)
