Objective: The objective of this study was to investigate the pathological alterations of methionine for chicken embryo.In recent years, amino acids are used in veterinary medicine for many purposes. They injected into hatching eggs to increase chick body weight and performance at hatch, but the adverse effects of amino acids have always been a major concern. There is scant information available about the pathological alterations of amino acids in the chicken embryonated eggs. Methods: Fertile chicken eggs were divided into two equal treatment groups as follows: phosphate buffered saline-injected group and methionine-injected group whose individuals were injected with a methionine solution at a dosage of 10 mg per Kg egg-weight. Embryos were re-incubated post-treatment and allowed to develop until day 18 after which; they were examined for macroscopic and microscopic lesions. Results: The germination of inoculated seed was significantly reduced, germ tubes of microconidia penetrated all parts of the thick, complex seed testa, and seed contents were destroyed. Pathogenicity tests indicated that F. solani caused lesions of black soft rot and complete deterioration within 5-7 days (100%). They also attacked Orobanche seeds, arresting their germination and causing maceration of non-germinated and germinated seeds after 5-7 days of incubation. This is the first investigation of the effects of F. solanim on host plant interactions with broomrape in melon.

Objective: The orange-red spectrum of the skin of electric yellow (Labidochromis caeruleus) is one of the idealistic and necessary schemas sought by aquarists and commercial producers. In this study, the effect of live foods meal on the skin coloration of juvenile electric yellow was examined. Methods: 270 fish with an average living body weight was 0.42 ± 0.11 g, and average total length was 3.3 ± 0.35 cm. Their sex was not taken into consideration. . The fish were fed twice in the morning and afternoon by 3-5 percent of the biomass for 8 weeks. The six different treatments (three replicates/treatment) used in the experiment were used. Skin color was measured in below the dorsal fin of all fish. Measurements were recorded at the end of the feeding trial using a Konica Minolta Chroma Meter CR400. Results: At the end of the trial, the carotenoid supplemented diets significantly increased the values of redness (a*), yellowness (b*), and chroma (C*), and decreased the values of lightness (L*) and hue (Hoab) on the tail, body, and head areas (p<0.05). luminosity (L*) and hue (H°ab) were less in fishes fed the diets with live foods and astaxanthin than in fishes fed the control diet with no pigment sources (p<0.05). yellowness (b*), and Chroma (C*) were greater in fish fed the culex and were less in fish fed the control diet(p<0.05). Results show that live foods used in this trial can be used as an alternative natural carotenoid source in electric yellow diets.

Objective: In recent years, farmers have shown great interest to using native drill planter rather than complex planters to grow vegetables. Methods: In this study, we tested a native planter Independent variables were the two types of substrate surface (asphalt and plowed field), three ground speed (3, 5 and 7 kph) and four types of seeds (tomatoes, onions, radishes and lettuce). Dependent variables were the seed’s lateral dispersion coefficient compared to the straight line, seed shedding rate per unit area. effect Percentage of metering device on seed viability, and breakage percentage of seeds after crossing the metering device. Results: The results showed that, the rate of seed shedding per hectare declines in all seeds along with increasing ground speed. However the lateral dispersion coefficient of the straight line planting has increasing trend along with increasing ground speed and the both parameters are lower in asphalt’s substrate surface than the cultivated ground. breakage percentage of seeds and effect Percentage of metering device on the viability of seeds after passing through the planter are also very low. It assume that use of the planter in front of method of hand cultivation reduce some costs such as costs of seed’s purchase.

Objective: The aim of the present study was to evaluate artificial insemination techniques on reproductive performance in Ghezel ewes synchronized with CIDR during breeding season. Methods: All ewes were treated with controlled internal drug release device (CIDR) inserted into the vagina of the ewes for 14 days. All ewes were treated a single intramuscular (IM) dose of PMSG was injected. In this experiment 120 head ewes divided into four subgroups randomly and experimental groups consist of: control 1, ram mating, n=30; control 2, ram mating plus 550 IU PMSG, n=30; group 1, laparoscopical intrauterine insemination plus 550 IU PMSG, n= 30; group 2, cervical insemination plus 550 IU PMSG, n= 30. Results: In this experiment estrus responses were similar in all groups (control 1, 76.7%; control 2, 93%; group 1, 96%; group 2, 100%). There were no statistically significant differences (P>0.05) between the treatment groups and the control groups for the estrus response. Pregnancy rates were 70%, 90.0%, 83.3% and 60% in control groups 1, 2 and AI groups 1, 2 respectively. Twinning rates (10% to 34.6%) and litter size (1.10 to 1.35) were significantly different in the treatment groups and the control group 1 (P<0.05). As a result, conception rate in the laparoscopical intrauterine insemination was higher than cervical insemination.

Objective: Castor (Ricinuscommunis L.) is an industrial oilseed that belongs to the family Euphorbiaceae. Castor is believed to be originated in East Africa probably Ethiopia. Although Ethiopia is known as a primary diversity for castor the knowledge on nature and extent of variation of the indigenous germplasm is limited. The present test was conducted to study the nature and extent of variability among Ethiopian castor accessions. Methods: The test was conducted at Melkassa and Arsi Negelle, in the Central Rift Valley of Ethiopiaduring the main season of 2013/14. A total of 105 accessions were arranged in a randomized complete block design with three replications. Data of 12 characters were collected and analyzed statistically. Combined analysis of variance over locations reveled the existence of significant variation among accession in all the traits considered in this study. The interaction between accessions and environment was significant for eight of the 12 traits studied. Results: The accessions showed a wide range of variation on days to first flowering (52-148), days to second flowering (65-161), days to first maturity (118-217), days to second maturity (142-237), inflorescence length (13-74 cm), node length (2-32 cm), number of nodes/plant (5-26), number of inflorescence/plant (1-26), plant height (89-356), number of branches/plant (1-9), number of capsules/plant (10-350), hundred seed weight (21-99 g),number of seeds/plant (30-990). Overall highest value of heritability, genetic coefficient of variability and genetic advance as percent of the mean was recorded for number of nodes/plant, number of capsules/plant and 100 seed weight.

Objective: Wheat is the most important crop in Iran. Self sufficiency in wheat production is one of the economic and food safety policies in the country. In spite of the efforts which have been made in this area, the mean of wheat yield in Iran is less than its world average. Methods: In order to identifying of the high yielding wheat lines with optimal characteristics and to determine the traits which could be used as the selection index for increasing of grain yield, 40 recombinant inbred lines derived from a cross between Norstar and Zagros cultivars were evaluated in a randomized complete block design with three replications. Results: Significant differences were observed among the lines for all of studied traits, except the spike weight, flag leaf area and the straw yield. Higher genetic diversity was observed among the inbred lines with respect to the kernel per spike, the number of spikes, the biomass and the straw yield. The Peduncle weight, second internode weight, number of kernels per spike per spike, number of the spikes and 1000 kernel weight traits showed a high degree of heritability. The highest genetic gain was estimated for the peduncle weight, the second internode weight and number of kernel per spike. Correlation, stepwise regression and path analyses revealed the number of kernels per spike and the number of spikes in plot had highest direct effects on grain yield. The analyses were carried out using WARD algorithm and standardized data. Cluster analysis based on all traits assigned the lines into groups.

Objective: In order to study the effect of different concentrations of IBA hormone on rooting of olive cuttings in spring and winter of 2012-2013 in a greenhouse in Jiroft, Iran. Methods: a split-plot experiment was conducted on the basis of a Randomized Complete Block Design in which hardwood cuttings of one-year-old olive plants cv. Manzanilla with the diameter of 0.7-1 cm were used. The main plot was devoted to cutting seasons at two levels of spring (late-May) and winter (late-January) and the sub-plot was devoted to IBA (indulebutyric acid) hormone treatment at five levels of 0, 1000, 2000, 3000 and 4000 ppm. Results: It was found that 3000 ppm IBA increased the number of roots, the percentage of rooted cuttings, branch length, and root:shoot fresh weight. In traits such as root length and root dry weight, the highest effect was observed under the treatment with 4000 ppm IBA. But, control treatment had the lowest effect on the traits of rooting in olive cuttings. Cuttings planted in spring showed the highest effect on their evaluated traits (by 10-15%) with a significant difference with those planted in winter. The interaction between hormone and planting time was significant only for root fresh weight.

Objective: Soil salinity is one of the major worldwide environmental constraints affecting agricultural production in arid and semiarid regions. Lack of proper management of water and soil resources lead to increase soil salinity and reduce soil fertility. On the other hand, it seems simple and cheap method of measuring soil salinity is necessary. The aim of this study was to determine the relationship between exchangeable sodium percentage (ESP) and sodium adsorption ratio (SAR) in some salt-affected soils of Marvdasht plain, Fars, Iran. Methods: To this purpose, fifty soil samples were randomly taken from surface (0-10 cm) and subsurface (10-20) cm from different fields of experimental site. Results: The statistical results of the study indicated that to predict soil ESP based on soil SAR the linear regression model ESP=0.941+1.119SAR with R2 =0.806 can be recommended.

Objective: In this article, a numerical study is conducted on mixing of two fluids in the liquid phase with two different concentrations of a chemical species in the electro-osmotic flow. Methods: The base liquid is an electrolyte which flows in a two-dimensional micro-channel having electrically charged walls. Lorentz electric force, which is used as stimulating flow factor, is created by applying an external electric field on the electric double layer (EDL) aroused by adjacency of electrolyte and charged wall. Results: To ensure the convergence of the results obtained from the computer program, equations are solved iteratively until the residual amount after solving each equation is less than machine error and independence of results from the number and location of network nodes is verified for an experimental flow. To increase the mixing efficiency, some square and triangle shaped obstacles are embedded on the micro channel wall. Herein, the fundamental principles for passive mixing as well as the effect of frequency and height of the barriers on mixing efficiency are studied. The obtained results from numerical solving of electro-osmotic flow in micro-channel are compared with the theoretical results and a very good agreement is observed.

Objective: Soil organic carbon has been the most important soil quality measurement factors and has intense relation with soil physical, chemical and biological characteristics. Organic matter and its components are important factors of soil aggregates constitution and stability and play significant role in its structure. So, this research has been done for achieving this purpose. Methods: This area is arounding saman _ one of the charmahalobakhtiari counties in distance 20_30 km northeast. In this study, from 127 point in 3 land uses of fruit garden, degraded range, and dry farming, soil sampling of surface depth 0_30 cm was done. The soil samples were analyzed chemically and physically. Also ,soil organic carbon supply, mean weight diameter, particle organic carbon in macro and micro soil aggregates and total particle organic carbon were measured. For considering lands username type effect on soil characteristics and organic carbon physical distribution in case study area, variance analysis by SAS software and comparing averages by dancon method were done. Results: Comparing soil characteristics in 3 land uses of garden, degraded range and dry farming showed that land uses changed on pH, lime and soil bulk density have not been affect significantly but have affected on total soil organic carbon, soil nitrogen, EC, soil organic carbon supply, mean weight diameter, particle organic carbon in macro and micro soil aggregates and total particle organic carbon. In garden land use, most total organic carbon rates, total nitrogen rate, soil organic carbon supply, mean weight diameter, particle organic carbon in macro and micro soil aggregates and total particle organic carbon has been observed. Increasing MWD in garden land use is related to high rate of organic material in this soil.
