Abstract. Fenugreek (Trigonella foenum–graecum) belongs to fabaceae family. It is evaluated as multipurpose and commercially important spice plant. It has lots of health benefits and some of them are listed as diabetes control, decreasing blood sugar levels, cholesterol levels, inflammation, loss of appetite. This research was carried out to determine the yield and some quality properties of one cultivar (Gürarslan) and 2 fenugreek lines (line–1 and line–2) in 5 different sowing dates (October, November, December, March and April) under Ordu ecological conditions during 2013–2014 years. Experiments were designed and applied in split block design with three replications. Plant height, pod number per plant, seed number per pod, pod length, branche number per plant, 1000 seed weight, biological yield, seed yield, harvest index, crude protein content, crude oil rate were determined as 30.13–63.90 cm, 3.0–11.33 number, 21.33–68.33 number, 10.50–14.0 cm, 1.0–4.33 number, 17–20.82 g, 161.48–378.44 kg da–1, 45.64–86.98 kg da–1, 19.91–43.08%, 9.64–10.32% and 2.26–4.93%, respectively. Significant differences were determined among the fenugreek cultivar and lines except crude protein content and crude oil rate. While the highest seed yield and crude oil rate were found in line–1 in 2nd sowing time, crude protein content was obtained in Gürarslan cultivar in 2nd sowing time and line–1 in 5th sowing time. Correlation matrix and PCA were conducted to find relationship among the examined properties. Generally, line–1 can be selected for crude protein content and crude oil in 5th sowing time and line 2 can be chosen for seed yield 2nd sowing time.

Abstract. In present study, it was investigated to determine the presence of Gram–negative enteric bacilli from dairy products including raw milk and cheese traditionally manufactured in Kilis. The antibiotic susceptibility profiles and ability of biofilm forming of strains isolated from Kilis local cheese were also researched. Totally, 30 Gram negative enteric bacilli that are members of the family Enterobacteriaceae was isolated from Kilis cheese sample. Out of 30 isolates, 11 strains (37 %) were revealed to be biofilm producer by Congo red agar analysis. 100 % of these isolates showed sensitivity to aztreonam, cefazolin, cefepime, ceftazidime, cefuroxime axetil, chloramphenicol, gentamicin, meropenem streptomycin and tetracycline. On the other side, 11 strains were resistance to clindamycin, erythromycin and penicillin. MAR indexs of these enteric isolates were found as 0.23. Our results clearly indicate that antibiotic resistance of biofilm–forming Enterobacteriaceae spp. in Kilis cheese may adversely affected the safety and quality of local foods and human health.

Abstract. Antimicrobial resistance has been an increasing problem in public health around the world. Natural plants can be utilised as an important source for antimicrobial agents to be used in place of synthetic drugs due to their costs and side effects. Thus, it is essential to find out new, effective, safer natural antimicrobial products. In the present study, in vitro antibacterial activities of different traditional plants against pathogen microorganisms were tested. The extracts of all plants were prepared in four different solvents (ethanolic, methanolic, hexane and aqueous) and then used for disc–diffusion method. Each assay was repeated in triplicate. The analysis was carried out using two–way analysis of variance (ANOVA). The highest antimicrobial activities were obtained by methanolic extracts of Sorbus domestica against E. coli, while Methanolic Extracts of Epilobium angustifolium were effective against Staphylococcus aureus, Klebsiella pneumoniae and Pseudomonas aeruginosa. In addition, Hexanic Extract of Tragacanth gum and S. domestica had high antibacterial activity against K. pneumoniae and P. aeruginosa, respectively.

Abstract. In order to obtain the optimum extraction technology for rapid and accurate determination of phenolic acids from dandelion in laboratory, methanol was used as extractant, and response surface methodology (RSM) was used to optimize the extraction process combined with the quality evaluation by the fingerprint analysis. Results showed that the input of cellulase was beneficial to the stability of the extraction. The liquid–material ratio promoted the extraction rate, and the methanol with the extraction time or the liquid–material ratio showed synergistic effect on the increase of extraction rate. Chlorogenic acid and caffeic acid were the main compounds and their match degree with the control fingerprint map were all 100 % according to the HPLC fingerprint analysis. Thus, the two compounds were used as main evaluation indexes to obtain the optimal extraction conditions, namely that liquid–material ratio of 300, methanol concentration of 40% and ultrasonic extraction time of 120 min. The obtained extraction process reduced the operation cost and maintained the stability of detection results. It could be directly used for the determination of phenolic acids from dandelion in laboratory.

Abstract. Environmental stresses change antioxidant and non–enzymatic activities of plant cells. Nanoparticles may help plants against drought stress. This study was conducted to evaluate the effect of titanium and silicon nanoparticles on antioxidant enzymes activity and some biochemical properties of Cuminum cyminum L. under drought stress. This study was conducted based on randomized complete block design in an arrangement of split plot with three replications, and irrigation content (50, 100, and 150 mm evaporation), and foliar applications of titanium and silicon nanoparticles, and soil application of superabsorbent polymer as factors. The results showed that levels of water, titanium, silicon nanoparticles, superabsorbent polymer, and their interactions were efficient on growth of Cuminum cyminum L. Drought stress decreased relative humidity, but increased antioxidant enzyme activity, leaf proline, and carbohydrate. Application of titanium nanoparticles increased leaf proline. It was observed a significant interaction between water availability, and fertilizers on ascorbate enzyme activity (P<0.05), so that most activity (0.193 µmol/mg) was observed in 100 mm evaporative pan and foliar application of titanium. In sum, drought stress increased carbohydrate, antioxidant enzymes activity and proline contents, and decreased relative water contents.

Abstract. The purpose of this study is to evaluate the genetic variability between red clover half–sib families in terms of yields of dry forage mass during regrowing, as well as seasonal yield stability and years of use. Ten red clover elite plants selected in the past by one or more breeding criteria underwent a re–pollination in 2014. Their polycross progeny (HSFs) were examined by cuts from the first to the fourth vegetation (2015–2018) for the following indicators: green matter yield, dry matter content, dry matter yield, time for cuts formation. ‘Nika 11’ and ‘Sofia’ 52 cultivars were used as a control for high summer productivity and adaptability. In early spring growth, the polycross progeny of elite genotypes did not significantly differ in dry forage mass. In contrast, as in late spring and summer regrowing, the effect of the family was significant (P<0.05). Genotypic effects are also observed in terms of growth rate. A genetic potential for increasing the yield of dry forage mass for both late–spring and summer regrowing was found for family 2 and 3. Valuable genotypes for the breeding in relation to yield stability over seasons and age of plants, respectively years of use, can be selected in family 7, which originated from a local wild–type germplasm. The high expression in the level and stability of the observed characteristics, as well as the high estimates of general combination ability, determined ‘Nika 11’ as an important genetic source in the breeding for high forage productivity in regrowing. According to these results, ‘NIKA 11’ is used as a major component in the formation of polycross groups with the selected families.
