Sevda Uçar Gelen | Ziya Gökalp Ceylan
Enterococcus species with lipolytic and proteolytic properties can pass directly from animal faeces or indirectly from contaminated water, equipment or storage tanks into milk. The present study focused on isolation and identification of Enterococcus species and to determine the microbiological characteristics of traditionally produced civil cheese. TMAB, Coliform, Enterococus and yeast-mold counts of 40 civil cheese samples made by traditional method were determined. In addition, Enterococus species was isolated and identified with Vitek2 compact system. total mesophilic aerobic bacteria counts were 8.22 log cfu/g; the number of the number of Enterococci were 5.77 log cfu/g, Coliform bacteria count were of 4.18 log cfu/ g and the number of yeast and mould were 6.35 log cfu/g. It was determined that the isolated 75 Enterococcus strains consisted of 33 Enterococcus faecalis, 23 Enterococcus durans, 12 Enterococcus faecium and 6 Enterococcus gallinarum and 1 Enterococcus avium. As a result, because of the production of fresh civil cheese under unhygienic conditions, its microbiological quality is low. This situation poses a potential health hazard to consumers.

The aim of this study was to determine effects of different dietary rosemary essential oil levels on growth performance, carcass traits and haematological values of breeder chukar partridge. Eighty (60 females and 20 males), 32-week-old breeder chukar partridge were randomly divided in five treatments, with four replicate pens with 4 birds each. Five experimental diets were formulated according to rosemary essential oil inclusion rates 0 mg/kg, 24 mg/kg, 48 mg/kg, 72 mg/kg and 96 mg/kg, respectively. The experiment lasted for 8 weeks. The chukar partridges had free access to ad libitum feed and water. At the end of the trial, 1 male and 1 female partridge were slaughtered for blood analysis. The obtained results showed that there was no significant difference in feed intake, body weight gain between the control and treatment groups. Dietary rosemary essential oil supplementation did not affect blood serum glucose, urea, triglyceride, total cholesterol, HDL-C and LDL-C levels in breeder Chukar partridges. It could be concluded that supplementing rosemary essential oil into Chukar partridges diet show no negative effect on growth performance.

Özdal Köksal
In this study, the change of farmer behaviour, which is thought to change slowly, over a 30 period, was evaluated in terms of information sources. In the study, the change in farmer attitudes with a longitudinal approach was designed in a process, and the data obtained from the same farmers and the same questionnaire forms were changed over time. A survey conducted in 1989 was repeated in the same region, in the same survey forms and in the same sample group (66 farmers) in 2019. In the analysis phase of the data obtained from the surveys, Multiple Compliance Analysis Technique was used. In the Polatlı District of Ankara Province, the long-term approach of 66 farmers, especially the changes in information sources and the non-logging habits of their businesses, has been determined with a longitudinal approach. The research results revealed that urban people have become close to rural areas and agriculture, and that their farmers have become close to district and provincial centres. As in all economic activities, research results support that the same jobs in agriculture for the long time do not have the opportunity to do the same and to be content with the knowledge left from the ancestor. This result is the most concrete indication that knowledge-based agriculture has become inevitable in every respect.
Mostrar más [+] Menos [-]Scanning of Dwarfing, Photoperiod Vernalization and Waxy Genes of Lines Carrying Rye Translocation in Reciprocal Recombinant Inbread Line Population Developed in Bread Wheat Texto completo
2020
Tuğba Güleç | Nevzat Aydın
The aim of this study is to screen the recombinant inbred lines (RILs) carrying rye translocation for the semi-dwarf (Rht), photoperiod (Ppd) and vernalization (Vrn) genes. Recombinant inbred lines were obtained by hybridization of bread wheat varieties Tosunbey and Tahirova-2000. Only the lines carrying 1BL.1RS rye translocation from population were used in the study. Parents and all of RILs were found to have Rht-B1a, which is a semi-dwarf allele, and Ppd-D1a allele, which is not susceptible to photoperiod. The vernalization alleles (Vrn-A1, Vrn-B1 and Vrn-D1) in the lines were also determined. It was determined that both parents and all the RILs had vrn-A1 allele, and not Vrn-A1c allele. It was determined that 151 of RILs contained vrn-B1 allele and 154 of them contained Vrn-B1 allele, while 131 of RILs had vrn-D1 allele and 174 of them had Vrn-D1 allele. In addition, molecular screening were carried out for waxy alleles (Wx-A1, Wx-B1 and Wx-D1) which were effective on flour swelling, water holding capacity and shelf life of bread wheat. As a result of the molecular data it was found that 141 of RILs carry all three alleles and named as “normal amylose wheat” and 164 of them had only Wx-A1 and Wx-D1 alleles, as known “low amylose wheat”. The results indicated that the population used in the research could be the subject of some researches, especially drought tolerance, and RILs could be used to develop genetic material carrying rye translocation for wheat breeding programs.

Kamile Ulukapı | Yusuf Kacar
Kohlrabi, which has increased production in our country in recent years, is a vegetable with high water consumption. The aim of this study was to determine the effects of different irrigation levels on plant and tuber growth and determine the appropriate irrigation level. In this study, vegetative growth and some tuber quality parameters of two different kohlrabi cultivars (Korist F1, Kolibri F1) at 4 different irrigation levels (I100 I75, I50, I25) were investigated. The experiment was carried out in unheated greenhouse as a pot experiment in April-June with three replicates and 10 plants per replicate. At the end of the experiment; number of leaves, leaf width (mm), leaf length (mm), tuber diameter (cm), tuber height (cm), tuber weight (g), tuber pH, total soluble solid content of the tuber and chlorophyll index were measured. The growth curves of the tubers were drawn and potassium (K), phosphorus (P) and sodium (Na) contents of the tubers were determined. In Kolibri F1, the highest tuber weight was obtained from the I75 irrigated plants with an average of 369.59 g. In Korist F1, the highest tuber weight was obtained from I100 applied plants with an average of 362.25 g. Especially in terms of tuber development, I100 has provided better results in water deficiency application. However, according to the results of the analysis, there was no statistically significant difference between I100 and I75 irrigation levels. It was determined that I75 irrigation level could be applied for kohlrabi cultivars in April-June cultivation period in Antalya conditions.

Gülendam Sezer | Adalet Mısırlı | Fatih Şen | Nihal Acarsoy Bilgin
In this study, it was aimed to determine the effects of gibberillic acid (GA3) applications on drop and quality changes of fruits on-tree storage period. GA3 (before peel color break, on the peel color break and both periods) and 20 ppm GA3 (before peel color break and on the peel color break) were applied to the trees, and the untreated trees constituted the control group. Fruits were harvested in five periods at monthly intervals from april. In the last harvest period, the average fruit drop rate was significantly higher in the control group (38.48%) than in the color transformation 10 ppm GA3 (9.44%) and before color transformation 20 ppm GA3 (19.28%). The fruit drop was not observed in the first and second harvest periods. Especially in the first period on-tree storage, the shell C* and h° values of the fruits in control were found higher than the GA3 application. As a result, twice application of 10 ppm GA3 in 'Valencia Late' orange reduced pre-harvest fruit drop, delayed peel color transformation and limited fruit quality change. Accordingly, it has been revealed that it allows on-tree storability until the end of august.

Kubilay Kurtulus Bastas
Erwinia amylovora, the causative agent of fire blight disease, threatens a lot of species of the Rosaceae family. Antibiotics and copper compounds in chemical applications are most frequently are applied, but these can be phytotoxic and cause resistant strains of the pathogen. In our experiments, 20 herbal materials were tested for their antimicrobial effectiveness against the fire blight pathogen in vitro and in planta. The air-dried plants ground into fine powder and extraction was performed at room temperature by maceration with 80% (v/v) methanol/distilled water. The minimum inhibitory concentration values were determined by using disc diffusion method and streptomycin was used as control in all experiments. Antimicrobial activity was evaluated by measuring the inhibition zones in reference to the pathogen. Among the tested plants, Szygium aromaticum, Thymus vulgaris and Rhus cararia showed a good antibacterial activity and they inhibited the growth of E. amylovora with inhibition zone diameter ranging from 21 to 27 mm at 20% (w/v) in absolute methanol compared to streptomycin (31 mm) in vitro conditions. In vivo tests were performed by using highly virulent E. amylovora isolate (Eak24b, 91%) grown on TSA medium and inoculation on young shoots of 3-year-old Gala variety of apple and Santa Maria variety of pear seedlings at 107 CFU ml-1 density of the pathogen. Disease severity (%) was assessed by by proportion of blighted shoot length to the whole shoot length and also efficacy of the extracts was determined by using Abbott formula. The highest efficacy was obtained by S. aromaticum and T. vulgaris extracts of reducing shoot blight of cv. Gala and cv. Santa Maria by 67.81% - 64-12% and 51.50% - 51.04% ratios, respectively. Obtaining results showed that some medicinal and aromatic plant extracts might be used against fire blight disease as potential new generation chemicals on pome fruits within integrated and organic control programs.

Bahar Argun Karslı | Fehmi Gürel
In this study, we aimed to investigate genetic differences between estivated Phassalis and hibernated Termessos native B. terrestris populations based on 20 microsatellite loci and two mtDNA gene regions (COI and cytb). The mean number of allele per locus, observed heterozigosity and inbreeding coefficients were determined 12.00 and 11.00, 0.68 and 0.65, 0.22 and 0.26 in Termessos and Phassalis populations, respectively. Pairwise FST value was calculated as 0.023 by using 20 microsatellite loci. According to the mtDNA COI gene region, all samples in both two populations were included in a single haplotype (Haplotype B). Four different haplotypes (Haplotypes 1-4) were determined according to the mtDNA cytb gene region. Pairwise FST value was calculated as 0.0013 according to the mtDNA cytb gene region. There were no significant differences between these two natural B. terrestris populations in terms of the 20 microsatellite and two mtDNA loci examined. According to results, life cycle differences of different native B. terrestris population are probably determined by environmental factors (photoperiod, temperature, flora, moisture, altitude etc.) rather than genetic influences.
