This study was conducted to collect, preserve and identify local oat genotypes grown in the Central and Western Black Sea region. Within the scope of the research, 251 local oat genotypes were collected from the places where they were cultivated in Düzce, Bolu, Zonguldak, Karabük, Kastamonu, Ordu, Sinop, Samsun, Amasya and Tokat provinces. The collected genotypes together with 4 standard oat varieties were taken into field trial in Ondokuz Mayıs University Faculty of Agriculture Research and Application field according to Augmented trial design in 2008 and 2009 growing seasons. As a result of the study, it was found that there were significant variations in terms of the parameters examined. Among the genotypes, the growth pattern of the 229 genotypes was perpendicular, The cluster genotypes of 163 genotypes were scattered, 132 genotypes were yellow in color, 157 genotypes were strongly stringy and 154 genotypes had callus hairiness. When the Matrix table was examined, it was found that the local genotypes with semi-horizontal growth pattern were not found in Amasya, Karabük, Kastamonu, Samsun and Tokat locations. In particular, parameters such as growth type, cluster type, color of husk, awn condition and callus hairiness. it provides ease of identification, since it does not affect the environmental conditions. In the light of this information, it is thought that the genetic variation is high in terms of ecology in which local genotypes are collected and will be beneficial for the protection of our genetic resources and for the future of national agriculture.

The increase of consumer demand for using natural products and reducing the use of non-compostable packaging materials have encouraged research on biodegradable polymers including natural components such as essential oils. Pomegranate seed oil (PSO) has active properties such as antimicrobial and antioxidant activities. The aim of this study was to prepare active polycaprolactone (PCL) films by using PSO. PCL films including PSO emulsions (5-30%), which were stabilized with nanocellulose (NC) particles, were prepared by casting method. The physical and active properties of PCL films were determined by means of water vapor permeability (WVP), mechanical properties, optical properties, release behaviour, and potential antimicrobial activity. The WVP values of PCL films was lower when incorporated with NC-stabilized PSO emulsions. The incorporation of PSO into PCL films in the form of NC-stabilized emulsions significantly reduced the transmittance and lightness values, which resulted in an increase in opacity. In the release tests, the slower release of PSO was observed for NC-stabilized films. The stabilization of PSO with NC showed to be less effective when high concentrations of oil (30%) were used. Film samples showed potential antimicrobial activity against Escherichia coli, and Listeria monocytogenes, however, a clear zone of inhibition around the film samples was not detected. Results also suggested that the antimicrobial effect was dependent on two important factors: the release behaviour of PSO through the film samples and, the direct interaction between PSO and microorganisms. These results showed that the combination PCL films and PSO stabilized with NC could be an interesting approach in active packaging technologies.

It is known that agricultural lands remain limited due to the ever increasing human population. That is why the necessity of increasing the crop production is constantly emphasized. In the crop production, quality should be increased along with yield. Nonetheless, there are amounts that people should take from each group of nutrients daily to ensure adequate and balanced nutrition. As known, malnutrition has negative effects on human health, which causes some diseases. Field crops, as well as other feeding groups, are of great importance in human nutrition. It is known that oil plants, which belong to the group of industrial plants, have an important place in human nutrition as in the vast majority of field crops. Thus, in this article, some important oil plants will be examined in terms of human nutrition.

Physalis peruviana (PP) is a popular exotic fruit due to its functional food properties. This product has a wide range of uses in the medical field, including treatments for cancer, malaria, hepatitis, dermatitis, rheumatism, weight loss, and diabetes. In this study, the PP element concentrations were investigated using a Wave Dispersive X-ray Fluorescence Spectrometer (WDXRF). Al, Ca, Fe, Mn, P, S, Zn, Cl, K, Mg, Na, F, Si, and B were detected, and the Ca, Fe, Zn, P, Na, Mg elements were found in significant amounts. Therefore, PP has some important health elements. For example, Mg and Mn may be associated with diabetes control. WDXRF is a cheap, quick, and non-destructive technique used in the elemental analysis of plant samples.

This research was carried out in the greenhouses of Pamukkale University Menderes Basin Agricultural Application and Research Centre in order to determine the effects of different blossom pruning on yield and quality in Ayza F1 tomato cultivars. The experiment consisted three different applications; pruning group having 6 fruits in flower bunch, pruning group having 7 fruits in flower bunch and control group without pruning. As the quality criterion in the tomato cultivar, total amount of water soluble dry matter (TWSDM %), pH, titratable acidity (TA mval 100 ml-1), hardness of fruit flesh (Newton) and antioxidant content (%) were determined. In addition, fruit diameter (cm), fruit length (mm) and weight (g) were detected. Yield parameters such as total yield (g plant-1), marketable yield (g plant-1), number of fruits (number plant-1), average fruit weight (g fruit-1) were considered detailed. Flower pruning having 6 fruits was prominent in terms of marketable yield, fruit weight, fruit diameter, fruit length and dry matter (DM) values. The effects of the applications on the quality characteristics such as fruit index, TWSDM and pH were found to be insignificant and their effects on DM, TA, fruit flesh hardness and antioxidant amount were detected to be significant.

In this study, the age, growth, and gonado-somatic index (GSI) of the Red mullet (Mullus barbatus ponticus Essipov, 1927) from the Eastern Black Sea coast of Turkey were examined. A total of 1466 M. barbatus ponticus were sampled between September 2010 and August 2011 from trammel net landings in Rize. The total length of Red mullet ranged from 7.42 cm to 17.80 cm and weight ranged from 9.59 g to 50.93 g, regardless of the sex. The sex ratio (♂/♀) was 0.46, with almost twice more females than males. The growth performance of M. barbatus ponticus in the study area is similar to that of the western populations of the same sub-species. A closed season of at least three months (from May to July) banning the use of even the stationary fishing gear will be beneficial for the sustainable stock of management of M. barbatus ponticus in the Black Sea.

Red beet (Beta vulgaris var. Cruenta Alef.) it is a flowering plant belonging to the family of Amaranthaceae and is cultivated in the regions extending from the west of Europe to all the Mediterranean coasts In Turkey; especially in the Aegean and Marmara regions. In the World, it is used in the production of milk and milk products, fruit juices, sauces, soups, confectionery, jelly, tomato paste, breakfast products, sausages and sausage products. In Turkey, in addition to these, it is widely used, in producing the turnip juice and pickles. There beet is particularly rich in minerals such as sodium, potassium, magnesium, calcium and phosphorus and also contains iron and selenium. Further; rich in antioxidant phenolic substances, betalain and flavonoid. In this study; antibacterial effect of extracts obtained from red beet outer shell and flesh inner part by using different solvents (ethanol, methanol and distilled water) on some food pathogens were determined by dise diffusion method. As a result of the research; the most antimicrobial effect was observed in the water extract obtained from the shell portion of red beet against Listeria monocytogenes with a 17 mm dilution diameter. This value was determined to be followed by methanol extract obtained from the interior of the red beet against Pseudomonas aeroginosa with a 16 mm dilution diameter. The lowest MIC and MBC values were on the Enterobacter aerogenes of beet peel methanol extract with values of 23.44and 31.25 μg / mL, respectively. All results were compared with the reference values of Eucastand CLSI laboratories and resistance and sensitivity were determined.

Soil moisture has a vital role in the cultivation of crops. Its sufficiency and availability to crop- water supplies depends on the management practices of soil and amount of available water to the soil. This study examines the influence of rice husk biochar on the water holding capacity of soil in the savannah ecological zone of Ghana. Increasing rate of rice husk biochar increased water-holding capacity of soils. 4t/ha rice husk biochar showed higher significant differences among the treatments. It is recommended that 4t/ha rice husk biochar should be applied to increase the water-holding capacity of the soil.

Against rapidly developing industry and increasing population, natural resources on earth are getting destroyed. One of the most important adverse effects on the environment is perhaps the depletion of ozone layer which protects the earth from harmful effects of UV radiation, especially UV-B. The effect of UV-B radiation can vary according to species. At high rates of UV-B radiation, many disorders in DNA, photosynthesis, morphological and physiological structure, and biomass accumulation in plants are observed. In this review, the effects of high UV-B radiation on terrestrial ecosystem are discussed.
