Abstract

A field experiment was conducted during summer season 2013 at AL-Anbar Governorate to study the response of peanut (Arachis hypogea L.) to different concentrations and types of boron under deficit irrigation conditions. A split-split plot design was laid out in three replications. Three concentrations of boron (0، 150، and 300) mg/l were sprayed. The experiment also included three levels of irrigation (50, 75 and 100) % of depth of irrigation. The results showed that the concentration of 150 mg/l of sprayed boron caused an increase in dry root and plant weight, pod yield and dressing ratio (12.50 g/plant, 380.96 g/plant,320.08  g/plant, %74.9 and 1.170 Kg/m3 respectively. The level of 75% of depth of irrigation gave best indicators for both dry root and plant weight, pod yield and dressing ratio (48.17 cm, 14.83 g/plant, 452.23 g/plant, 357.25 g/plant and 87.6% respectively. The results also showed that the effect of triple interaction between types and concentrations of boron and levels of irrigation was insignificant for most of the traits except dry plant weight.

Abstract

This study was carried out in the Syrian coastal in Tartous governorate, during the growing season 2014, to study the effect of four plant densities (10.00, 13.33, 20.00, and 33.33) plant/m 2, and three levels of phosphate fertilizations (107.2, 160.8, 214.4 kg/ha of super phosphate P2O5 46%), besides the control, on quality traits (nitrogen, crude protein, phosphorus and potassium) of the coriander plant. The experiment was designed in a Randomized Complete Block design (RCBD) with a split plot arrangement of treatments with three replications for each treatment. The results revealed significant differences between treatments for most of studied traits, in addition to an interaction effect between plant density and fertilization. Although, the densities (10, 13.33 .20 plant /m 2) varied in their effect, but it significantly outperformed the highest density (33.33 plant/m2). The treatment 10 plants/m2 was more importance in terms of increasing the plant content of N, P, K. On the other hand, most of the measured characters were increased as a result of the increasing rates of phosphate fertilization. The treatment (160.8 kg/ha of P2O5) had a significant superiority upon on the rest of the treatments in terms of its effect on phosphor, nitrogen and crude protein, whereas the treatment )214.4 kg/ha (increased each of the content of the seeds of both of nitrogen and phosphor. The interaction effect between the highest plant density (33.33/m2) and the highest level of phosphor fertilization (214.4 kg/ha) had the superiority upon the other treatments in term of increasing each of seed content of P, N, protein, and K content of vegetative growth.

Abstract

The present investigation was carried out at Latakia Agricultural Research Center, during (2011-2013), to study the propagation of male kiwi trees by wooden cuttings at two collecting dates (January and February). NAA and IBA regulators were applied at two concentrations (5000, 6000 ppm). In addition, of four treatments of the mixture of both regulators. The cuttings were planted within a glasshouse for 60 days under sprinkle irrigation conditions in order to study the effect of some factors (collecting date, location of cuttings on shoot, type of regulator and its concentrations) on some characters of cuttings (rooting ratio%, weight and size of roots, and weight and size of shoots. The results showed that the first collecting date (January) was significantly better in terms of weight and number of roots and shoots and rooted cuttings number. The rooting ratio was 64.9%, 54.3% respectively. According to cutting location on the shoot, the middle and basal cuttings were exceeded significantly the typical one in term of roots weight (20.31, 19.81, 15.55 g respectively) and also according to root size (20.55, 20.06, 15.57 cm3 respectively). The NAA and IBA regulators; had different effects, where the regulator (NAA) was significantly superior to the regulator (IBA) and the mixture treatments in terms of the average number of roots / cuttings. While the shoot weight and size were higher at IBA and mixture treatments than NAA. The mixture treatment 3000 ppm of (IBA + NAA) gave high values of roots weight and size. The treatment of 1500 ppm of mixture (IBA+ NAA) was significantly superior compared to the other treatments in terms of the number of rooted cuttings (75%) comparing to the control (28%).

Abstract

Consumers, especially in poor countries, suffer from many kinds of meat adulteration by substituting cheaper and less nutritious meat with costly ones. Traditional morphological analysis or others based on component analysis are usually applied to identify undeclared meats, but these methods often produce incorrect or unreliable results, Therefore, finding more precise and reliable methods is critical in food authentication. DNA-based techniques have been widely used in this field due to their sensitivity, speed and high accuracy. In this study, species- specific PCR technique was employed to analysis 18 sheep meat samples to detect substitutions with beef, goat, chicken, turkey or pork meat. The detection process was based on specific primers targeting cytochrome b coding gene. The results showed that all samples were mixed with one or more types of meat. The expected fragment of DNA was obtained from each pair of other used primers. Cheating with goat meat was the most frequent among samples with a ratio of 94.44%. while the lowest frequent was with turkey 16.66%, and finally, adulteration with pork meat was not recorded in any sample.

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

This research was carried out on 1639 heads of camels in two Syrian governorates, Homs and Deir- Ezzour during the period of March 2010 till February 2011 to recognize prevalence of Ringworm infection under the conditions of breeding release. Clinical symptoms of infection were recorded i.e. age of infected animals, sex, and general condition. The infections were listed according to the seasons of the year. The clinical symptoms appeared in the form of lesions and distinctive circular spots covered with dry dense white scurf, localized mainly in the head, neck, chest, front standings and sometimes in all over the body. Results showed sufficient difference (p<0.01) in the prevalence of infections among the ages of infected animals, where the infections were greater in small aged camels till three years old where the ratio was (31.87%), while it was (9.58%) in camels their ages within the range (3-10) years. Infection prevailed in both sexes, male and female, where the ratio of infection was greater in old female camels (10.05%) comparing to old males (6.01%), also it was greater in small females (35.4%) comparing to male animals (27.63%), but there is no significant difference between the two sexes. The ratio of prevalence infections varied according to the seasons of the year with significant difference (p<0.001). It was for old camels in winter, autumn, summer and spring (14.63%،, 10.95%،, 7.69%, 4.98%) respectively. While the ratio in small camels with significant difference (p<0.05) (40.94%, 33.60%, 29.26%, 23.84%) respectively. These results is considered important for charged people in the veterinary and health sectors, because it helps them in setting protective schedules programs that can reduce the ratio of prevalence the infection in animal.

Abstract

The objective of this research is to study costs structure of almonds production in Homs governorate for the agricultural season 2015. To achieve the targets, the research depended on the econometric and statistical analysis of the primary data which was collected by interviews with the farmers of the studied region. The results of the cost structure analysis of the almonds production showed that the variable costs accounted approximately (66.11) % of total costs, while the fixed costs accounted (33.89) % of the total costs. The quantitative analysis showed that the optimal size of production that decreases the costs was (12.9) tons, but the optimum area was (49.54) dunum. The estimated elasticity of costs, amounted (1) at the optimum level of production, and the minimum price was calculated as (148673.08) sp/tons, and the function supply in long term was derived. A positive relationship between quantity supplied of almonds and price, when price is greater than (148673.08) sp/tons. Also, the results showed that the average cost decreases until it reaches to optimal level of production, while proportion economies of scale reach the maximum value 100% at optimum level of production average cost.
