Abstract

This research work was conducted at the Agricultural Scientific Research Center in Tartous, GCSAR in the summer of 2016 to study the ability of using wood coal ash in composting of tobacco residues. The study included four experimental treatments, consisting of a control (tobacco residues with calcium carbonate without ash), and three other concentrations of ash (10, 15 and 20%). The complete randomization design was followed and based on three replicates per treatment. The results showed that compost’s pH increased from 7.76 to 8.21, C/N from 17.44 to 19.61 and calcium content from 1.31% to 1.6% with the increase in the concentration of ash, and the treatment (20%) of ash increased P and K contents in the compost (0.475% and 1.46%) respectively, while the addition of ash to the residues of tobacco caused a decrease in the content of the produced compost of nitrogen and magnesium.

Key words: Tobacco residues, Compost, Ash, Nitrogen, Phosphorus, Potassium, Calcium, Magnesium, C/N.

Abstract

The experiment was conducted in order to study the effect of osmotic stress on some morphological parameters in eight Syrian wheat varieties (Triticum Spp.) using plant tissue culture technique. Osmotic stress was imposed by adding different concentrations of sorbitol to (C₆H₁₄O₆) the culture medium (0, 110, 220,330 and 440 mM), which are equal to -0.82, -1.09, -1.44, -1.79 and -2.14 MPa, respectively on the osmotic potential basis. Plant length (cm), number of leaves, number and length (cm) of roots, plant fresh and dry weights (g), plant water and dry weight content (%) were measured. Results revealed a genetic variability in the response of the investigated varieties for osmotic stress based on the studied parameters. Progressive reduction in the studied parameters occurred as osmotic stress increased compared to the control. Cluster analysis, based on the relative values of all the growth parameters response to osmotic stress, showed three distinct groups: the osmotic stress tolerant group, which included four varieties (Doma1, Bohouth11, Bohouth8 and Guolan2); the moderately osmotic stress tolerant group, included three varieties (Doma4, Cham3 and Bohouth7) and the osmotic stress susceptible group, included one variety (Cham10).

Abstract

The study was conducted to evaluate the effects of supplementing selenium, zinc and combination of them on the level of antioxidants and some blood biochemical indicators of 12 individual Kurdi rams, aged between 16 – 18 months. The rams were divided to four groups and each group contained 3 rams. The control group, basal diet without Se and Zn, the second group selenium (sodium salinate) was added as 0.5 mg / kg of feed, the third group zinc (zinc sulphate) was added as 100 mg/kg of feed, and the fourth group selenium with zinc were added as 0.5 + 100 mg/kg of feed, then given by gelatinous capsules daily for 90 days. Blood samples were taken from the rams (three for each treatment), on the 30 days, 60 days and before ending the feeding trails (90 days). The results showed a significant increment in Testosterone hormone, blood urea, glutathione (GSH) and Malondialedhyde (MDA) in the blood serum in the groups that added Se, Zn and combinations of them to the feed compared to the control group. An increase in the concentration of the Aspartate Transaminase (AST) and Alanine Transaminase (ALT) in blood serum in the groups that added Se, Zn and combination of them to the feed compared to the control group. In addition, the total protein in the blood serum did not differ significantly between treatments on the 30, 60 and 90 days of the experiment. The results concluded that the addition of selenium and zinc supplements improved significantly of the situation of antioxidants, Testosterone hormone and some serum biochemical indicators of Kurdi rams.

Abstract

PCNA is synthesized in early G1 and S-phases of cell cycle. Tight linkage to cell proliferation has led to the investigation of its role in the evaluation of tumors for prognosis. The aim of this study is to use computerized image analysis to measure PCNA and CD31 antibodies in a series of canine melanocytic tumors to assess density of marked cells by these antibodies, and to correlate density of marked cells with malignant degree of these tumors through comparative study between CD31, PCNA and microscopic aspect. 12 dog melanic tumors were diagnosed during the period 2001–2010 in Pathology Department USAMV Cluj-Napoca, for PCNA expression study, and 10 samples of them were treated with CD31 marker by immunohistochemical for comparative study. Immunohistochemical method is staining the tissue sections by primary antibody CD31 and develop process with DAB Chromogen and alkaline phosphatase Chromogen. Immunofluorescence method is staining the tissue sections by primary antibody PCNA and develop process with fluorochrome-conjugated secondary antibody-Rhodamine. Images were captured by using a microscope (Olympus BX51). All dog melanic tumors were positive with PCNA marker. 58% were positive according to Proniewska’s classification. All melanic tumors had a low grade of PCNA according to John’s classification. The high values of mitosis concurrent approximately with big values of PCNA percentages in majority cases. The malignant melanoma had high PCNA percentages than melanocytoma. The epithelioid type cell had big PCNA percentages comparatively with other type cells. There wasn’t any relationship between necrotic zones and infiltrated lymphocytes and PCNA percentages. The high percentages of PCNA had in majority cases a big number of micro vessels /fields marked by CD31. The malignant melanoma had a big number of vessels/field and high percentages of PCNA than melanocytoma. There wasn’t any relationship between grade of PCNA and percentage of vessel area / total area, Average of perimeter and average of vessel area. PCNA and CD31 markers had a significant effect in evaluation of aggressive of tumors.

Abstract

The effect of temperature on the development of the predator Hippodamia variegata (Coleoptera:Coccinellidae) reared on the green peach aphid Myzus persicae Sulzer (Homoptera:Aphididae) was determined at five constant temperatures (15, 20, 25, 30 and 35)°C under laboratory conditions. The present study was conducted at Latakia Agricultural Research Center during 2015 and 2016. This study aimed to determine the impact of temperature on the development of the predator H. variegata to identify the suitable temperature for rearing this predator. The duration (days) and survival (%) were measured for this predator. Results showed that temperature had a significant effect on the development of H. variegata immature stages, whereas the development time from larvae to adult decreased with increasing temperature at thermal range (15-35)°C. The longest larval developmental duration was 24.84 days at 15°C, and the shortest duration was 4 days at 35°C. Also, the shortest pupal duration was one day at 35°C and the longest period was 9.84 days at 15°C. The lowest developmental time from eggs hatching to emergence of adults was 6 days at 35°C, while the longest developmental time was 36.84 days at 15°C. Also the ratio of larval survival was affected by temperature, this ratio was (26%, 52%, 77%, 34%, 4%) at (15, 20, 25, 30 and 35)°C respectively. The results of statistical analysis showed that there were significant differences between the five constant temperatures in all studied biological characteristics, and the temperature 25°C was suitable for a successful rearing of the predator H. variegata.
