Item Effects of different improvement methods on some soil properties in a secondary succession rangeland(Uludağ Üniversitesi, 2011) Mut, Hanife; Ayan, İlknurThis study was conducted between 2005 and 2008 in a native pasture which was ploughed 30 years ago and abandoned, located in Ondokuz Mayis University Campus in order to investigate the effects of different improvement treatments on chemical characters of pasture soil. Treatment application started in 2006; i) control, ii) aeration, iii) early cutting, iv) commercial fertilization, v) sheep manure application, vi) reseeding, and their combinations. The effects of applied pasture improvement treatments showed differences both in the same year and among the years. There was an outstanding increase in the plots where manure alone was applied; however the increase was not so distinctive in the plots where manure was applied with other treatments (manure and its combinations). Soil physical properties were improved with extra organic matter. Electrical conductivity values of the soil samples of the experimental area were 0.568 – 0.793 dS/m in 2006, 0.459 – 0.675 dS/m in 2007 and 0.289 – 0.698 dS/m in 2008. Potassium, calcium and magnesium contents of the soil samples were very high and changed between 0.261 and 0.798; 28.333 and 37.417; 7.958 and 15.083 cmol kg-1, respectively. In the 3-year study, it was concluded that native pastures should definitely be improved by implementing appropriate improvement methods considering climatic conditions, soil characters, plant species and their botanical compositions.Item Effect of treatment with cylindamycine in an outbreak of coccidiosis in goat kids in Turkey(Uludağ Üniversitesi, 2011) Temizel, Ethem Mutlu; Demir, Gülşah; Selçuk, Özgür; Çatık, Serkan; Şenlik, Bayram; Şentürk, Sezgin; Uludağ Üniversitesi/Veteriner Fakültesi/İç Hastalıkları Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Parazitoloji Anabilim Dalı.The purpose of the present study was to investigate the effect of Cylindamycine in saanen goats kids suffering from naturally occuring coccidiosis. 13 kids were found to be suffering from different degrees of coccidiosis. Fecal samples were submitted from all of the diarrheic kids in the goat flock for virological, bacteriological and coccidial examinations. Bacteriogical cultures and flotation examinations of faecal samples were evaluated. In clinical examinations, all kids showed dysentery, tenesmus, inappetence, and weakness. While total per oocyste counts were detected as 675500 opg (per gram oocysts) before the treatment, were detected as low as 24020 opg at end of day 14. Clindamycine applications in addition to managemental measurements may be useful to reduce the oocyst counts and to improve of clinical status.Item Effect of salicylic acid on Na+ accumulation in shoot and roots of tomato in different K+ status(Uludağ Üniversitesi, 2011) Abdi, Gholamreza; Mohammadi, Mehdi; Hedayat, MohammadTomato plants grown in nutrient solutions with different K+ levels were used to study the effect of salicylic acid and Potassium status on Na+ uptake and Na+ accumulation in the shoot and root. Changes in the nutrient K+ levels induced evident differences in internal K+ content. When low and normal – K+ plants treated with SA were exposed in saline condition (50 mM Nacl) during experiment, Na+ uptake in low- K+ plants was greater than in normal – K+ plants. At the presence of SA, Na+ uptake in low- K+ plants was lower than low- K+ plants alone. Normal – K+ plants plus SA showed lowest amount of Na uptake and accumulation. In addition, K+ starvation favored the Na+ uptake and the Na+ accumulation both in the root and in the shoot. When the plants were exposed to heat stress by a sharp increase of the temperature to 320 C during the same period of time, the stimulating effect of K+ starvation on the water uptake was even greater. The high temperature increased Na+ uptake in both types of plants, but the Na+ accumulation in the shoot was only favored in low K+ plants.Item Serum biochemical profile of broiler chickens fed diets containing rosemary and rosemary volatile oil(Uludağ Üniversitesi, 2011) Polat, Ümit; Yeşilbağ, Derya; Eren, Mustafa; Uludağ Üniversitesi/Veteriner Fakültesi/Biyokimya Anabilim Dalı.; Uludağ Üniversitesi/Veteriner Fakültesi/Hayvan Besleme ve Beslenme Hastalıkları Anabilim Dalı.The study was conducted to determine the effects of dietary supplementation rosemary aromatic plant, rosemary volatile oil and α-tocopherol acetate (Vitamin E) on serum variables of broilers fed on maize-soybean meal based diets. Eight hundred 1-d-old Ross-308 male chickens were weighed and randomly divided into 1 control and 7 experimental groups each with 10 replicates of 10 birds. There were 8 dietary treatments: (VitE1) control without rosemary and rosemary volatile oil only with 50 mg/kg vitamin E; (R1) 5.7 g/kg ground rosemary leaves; (R2) 8.6 g/kg ground rosemary leaves; (R3) 11.5 g/kg ground rosemary leaves; (RO1) 100 mg/kg rosemary volatile oil; (RO2) 150 mg/kg rosemary volatile oil; (RO3) 200 mg/kg rosemary volatile oil and (VitE2) 200 mg/kg vitamin E. Broilers consumed the diets and water ad libitum. After 42 days, 80 animals were randomly selected for serum biochemical profile analysis involving ceruloplasmin, superoxide dismutase activity (SOD), transferring, albumin globulins ratio (A/G), total cholesterol, creatin, urea, alanine aminotransferase (ALT) and aspartate amino transferase (AST). While serum transferrin, urea level and ALT-AST activity were not statistically different among groups serum ceruloplasmin (p< 0.000), SOD activity (p<0.05), albumin/globulin ratio (p< 0.000), total cholesterol (p<0.001), creatinin (p<0.05) and AST (p< 0.000) level were found to be significantly different. In conclusion, the Rosmarinus officinalis plant and its volatile oil have increasing effect on serum SOD activity and effect positively oxidation mechanism. On the other hand, it can be assumed that rosemary plant created hypocholesterolemic effect in this study.Item The potential of corn (Zea mays) for phytoremediation of soil contaminated with cadmium and lead(Uludağ Üniversitesi, 2011) Mojiri, AminA study was carried out to investigate the potential of Corn (Zea mays) for phytoremediation of soil contaminated with Cadmium and Lead. Soil samplings of 0-20 cm depth were taken from the Chaharmahal Bakhtiari province in the western of Iran. Corn plantlets were planted in pots containing 3 kg of these soils. The experiment consisted of 9 treatments including soil without cadmium and Lead (T1), soil contaminated with 2 mg/kg concentration of cadmium (T2), soil contaminated with 4 mg/kg concentration of cadmium (T3), soil contaminated with 8 mg/kg concentration of cadmium (T4), soil contaminated with 16 mg/kg concentration of cadmium (T5), soil contaminated with 6 mg/kg concentration of Pb (T6), soil contaminated with 12 mg/kg concentration of Pb (T7), soil contaminated with 18 mg/kg concentration of Pb (T8) and soil contaminated with 24 mg/kg concentration of Pb (T9). Samples were taken for testing, after 60 days. Physical and chemical characteristics of soil such as soil texture, cation exchange capacity, pH, electrical conductivity, organic matter and extractable cadmium and lead were measured before and after the test. The evidences provided by this experiment indicated that Corn is an effective accumulator plant for phytoremediation of cadmium and lead polluted soils.Item Seed germination and dormancy breaking techniques for echinacea purpurea L.(Uludağ Üniversitesi, 2011) Fariman, Zahra Karimian; Azizi, Majid; Noori, SamiraEchinacea purpurea (Asteraceae) is an important medicinal plant known as a disinfectant. Its germination percentage and germination rate is generally low due to dormancy. Dormancy and germination requirements were investigated in this plant. Seeds of Echinacea purpurea were subjected to different treatments including various levels of GA3 (100, 200 and 300 ppm), KNO3 (0.5, 1 and 1.5 percentage) and Cold stratification (7, 14, 21 and 28 days). The germination percentage and germination rate significantly increased in all of treatments than control. The highest germination and germination rate were obtained in Cold stratification treatment that induced about 98% germination. The mean germination time also improved in all of treatments than control. Lowest mean germination time also was observed in Cold stratification treatment.Item In vitro culture of carnation (Dianthus caryophyllus L.) focusing on the problem of vitrification(Uludağ Üniversitesi, 2011) Kharrazi, Mahdiyeh; Nemati, Hossein; Tehranifar, Ali; Bagheri, Abdolreza; Sharifi, AhmadThis study was conducted to evaluate the effect of plant growth regulators on in vitro shoot multiplication, vitrification and rooting of two carnation cultivars (Eskimo Mogr and Innove Orange Bogr). Isolated axillary buds were cultured on MS medium supplemented with different levels of Benzyl amino purine (BAP) or kinetin (Kin) in combination with 0.2 mg/l NAA and shoot multiplication and vitrification rate were tested. Then different concentrations of Naphthalene acetic acid (NAA) or Indole butyric acid (IBA) on root induction of regenerated shoots were surveyed. Shoot regeneration and vitrification were influenced by the cultivar, kind of cytokinin and its concentration. Eskimo Mogr produced more shoots in comparison with Innove Orange Bogr (6.17 and 3.83 shoots/explant, respectively). BAP-containing media had more shoot multiplication and vitrification than Kin and by increasing the concentration of cytokinin, shoot multiplication and vitrification increased. There was a negative correlation between plant height and internode length with vitrification (-77% and -85%, respectively). By considering the amount of multiplication and rate of vitrification for obtaining the highest number of normal shoots, MS medium containing lower concentration of BAP (1mg/l for Eskimo Mogr and 2 mg/l for Innove Orange Bogr) and 0.2 mg/l NAA is recommended. Rooting of regenerated shoots was dependent on the cultivar. The highest root percentage for Eskimo Mogr (83%) was achieved on the medium supplemented with 0.5 mg/l NAA, while for Innove Orange Bogr (98%) it was obtained on the medium containing 1.5 mg/l IBA.
