2020
Neval Topcu Altıncı | Rüstem Cangi | Deniz Üstün
Plants are constantly exposed to adverse conditions in their environment, which may occur in different ways, limiting their growth. These negative states that affect and / or prevent growth, development and metabolism in plants are called stress. Salicylic acid (SA) is a hormone-like substance commonly found in plants and is now accepted to play an important role in regulating plant growth and development. Salicylic acid also increases the tolerance of plants under abiotic stress conditions such as salinity, high and low temperature, water, heavy metal, frost and drought stress. This study is one of the important white wine grape varieties belonging to Turkey's Narince grape varieties growing in Tokat made widely used. Salicylic acid (SA) was applied to the plants in 4 different doses (0, 0.5, 1.0, 1.5 µmol l-1) before high temperature stress to be applied and they were exposed to high temperature for 12 hours at 40°C in the growth chamber. At the end of the 21 days after the stress application, shoot length (cm), fresh -dry shoot and root weights (g) were taken in order to follow the plant growth from the plants. Proportional water content (%), Ion flow (%) to reveal the effect of salicylic acid and the cell membrane damage rate (%) was calculated.

The aim of this study was to determine the effects of vermicompost application on the growth of pepper seedlings. Fertilizer doses and application time applied to plants are among the most important factors affecting seedling quality in seedling production. Vermicompost products have many advantages from plant development to soil regulating effects, antioxidant effect and the use of all kinds of wastes (plant, animal, industrial, etc.) in production. Seedling mortar (70% peat and 30% perlite), which was constituted in the study, constituted the control group of the study. Pepper seedlings were grown by adding different doses of vermicompost (5, 10, 20%) to this control group. The properties of the vermicompost used were pH: 7.5, EC: 2.15 dS m-1, C / N: 18.71, organic matter: 64%, N: 1.25%, K2O: 1.02%, P2O5: 0.55 %). In the study, full fertilizer (EC: 1) dose and semi fertilizer (EC: 2) dose were applied in fertilization. Köylüm pepper varieties was used in the study. Total output rate (%), stem length (cm), stem diameter (mm), number of leaves (number), stem length (cm), wet and dry leaf weight (g), wet and dry body weight (g), wet and dry root weight (g) properties were determined. According to the control group, 10 and 20% vermicompost application of pepper seedlings wet weight, dry body weights and wet and dry root dry weights were statistically increased. The first emergence of plant seedlings and their marketable times were withdrawn early by vermicompost application. At the end of the study, it was determined that some of the properties examined with vermicompost application to control mortar increased. Vermicompost application showed good performance in working as an organic fertilizer that can be mixed with peat and perlite mixture.

Muhammed Taşova | Hakan Polatcı | Mahir Özkurt
In this study, the average drying times of the Frigos, Bilensoy, Nimet and Prosementi alfalfa varieties were determined by drying in a convective dryer (50, 60 and 70°C) and in the open (sun). In addition, the most suitable thin layer drying models were determined, which are important in controlling the drying processes and developing new product-specific dryers. In drying processes, the moisture content of the product was dried up to 10% compared to the wet base. The first moisture contents of the specified varieties according to the wet base are respectively; 76.20, 75.88, 76.13 and 75.07%. In drying processes, it was determined that drying method and temperatures changed average drying times. The longest drying times were determined in the Frigos variety, which was laid in the sun and dried. When the Frigos variety was dried in the oven at 50, 60 and 70°C, the average drying times were determined as 11, 10 and 6 hours. Time-dependent moisture ratios were determined, processed in thin layer drying models and the mathematical model that best predicts drying curves was determined. While creating curves, Page, Midilli, Yağcıoğlu models were used. While acceptable reliability values were found as in all models, among the models, the highest stability value (R2) was found by Midilli was found in equality.

2020
Fatih Hancı | Gizem Tuncer
The aim of this study was to investigate the effects of exogenous Melatonin (100, 300 and 500 µM) and L-tryptophan (125, 250, 375 ppm) applications on some growth parameters of lettuce plants grown under salt stress. The study was carried out under semi-controlled greenhouse conditions in spring (March/April) season. The exogenous applications to lettuce plants were carried out two times as foliar spraying. Salt stress was generated by adding NaCl (0 mM, 100 mM, 200 mM) to irrigation water. The complete randomized design was used with three replications in this experiment. At the end of the study, it was found that the highest doses of exogenous applications had the highest effect on the parameters of the number of leaves, salinity necrosis, fresh leaf weight, fresh root weight, and total surface area of lettuce plants under 200 mM salinity condition. When the effects of the subtract on these values were compared, the effect of melatonin was found to be more pronounced. Leaf width, leaf length, and leaf surface temperature values were not affected by the external application. These values only changed depending on salt concentration. As a result of the study, it was concluded that the application of 500 µM melatonin significantly increased salt tolerance in lettuce plants. However, in order to reach a more general conclusion, the dose ranges and genotype/variety numbers should be increased.

The African giant rat (Cricetomys gambianus, Waterhouse) is a wild rodent in sub-Saharan Africa widely hunted as popular meat delicacy. Domestication of this rat has been poor, probably due to nutrition among other factors. Developmental studies of the duodenum, jejunum and ileum as well as investigations of diet-based structural modifications of the small intestine were carried out in the rats using neonates, juveniles and adults with the aim of providing useful research information which could lead to improved domestication. The mean body weights of the animals were 39.67±1.45 g, 225.00±25.00 g and 742.90±62.13 g, respectively for the neonate, juvenile and adult rats. Significant differences were also observed in the villus height, villus width and crypt depth between the neonates and juveniles, unlike between juvenile and adult rats. These changes in intestinal morphology between the neonate and juvenile rats could be a measure of the neonates’ adaptation to shifts from digestion of maternal milk to the consumption of solid and semisolid forages. Respectively for neonates, juvenile and adult rats, 188%, 228% and 30% increases in villus height for the duodenum, jejunum and ileum respectively, were observed. This is suggestive of larger surface area of the small intestine for digestion and absorption. This study elucidates the structural modifications of the small intestine which can be applied to dietary modifications in response to age in an effort to achieve a more successful domestication of the animal.

Sezai Alkan | Ömer Ertürk | İsmail Türker
Eggs were coated with propolis in order to determine its effect on egg quality and total bacterial count. Effect of storage time prior to propolis coating was also studied. Eggs were obtained from a local farm, coated with 0, 3, 6 or 9% of propolis and stored at 4 ºC with a humidity of 75% for 30 days. A total of 18 eggs were used for egg quality traits and 6 eggs were chosen for microbial activity for each group. Bacteria were recovered with sterile cotton swabs from egg surfaces. Colonies with different morphology and color were detected. 11 bacterial species were determined following the characterization of 14 isolates. Elevated levels of bacterial counts were detected for daily eggs, which were significantly higher than those stored for 30 days. The quality traits of the daily eggs have also been found higher compared with the other groups. It was observed that coating the eggs with varying concentrations of propolis lead to significant differences in the total bacterial counts of the eggshells. Moreover, the egg quality traits which decreased with the increase in storage time have not been further affected with propolis coating.
