Cigdem Elgin Karabacak | Aysel Yeşilyurt Er
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.

This study aims to fully controlled production of european catfish (Silurus glanis) and to increase fertilization and survival rates using different solutions and methods, enrichment of natural stocks with the obtained larvae and to provide participation as a new species in addition to species cultivated in Turkey. The study was carried out in Gürle Trout Farm in Manisa province. Eggs and sperm, that had been obtained from the broodstock, exposed to various fertilization methods and the fertilized eggs were put in the zuger jars and made triplicate trials. As a result, in this study, under the light of the findings obtained from different fish that was captured in different times and from two different regions; eggs that were treated with the urea-salt solution fertilization, eying and survival rates were higher than only salt solution application. Urea-salt solution for 10 minutes and the salt solution for 10 minutes were more successful. In addition, the time problem of working with living materials has become one of the biggest obstacles to this work. It is imperative that the reproductive cycle occurs once a year and in case of failure, it is needed to wait for the next cycle. In this context, it was not possible to tolerate the problems experienced in egg-taking, fertilization and survival activities in the last attempt. Therefore, the project had to be terminated here.

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.

Antimikrobiyal duyarlılık testleri, ilaçların keşfedilmesi, epidemiyoloji ve terapötik sonuçların tahmini için kullanılabilmektedir. Günümüzde mikrobiyal yaşamdaki dirençlilik artış göstermekte olduğu için antimikrobiyal bileşikler etkilerini kaybetmekte ve bu durum onları tehlikeye sokmaktadır. Ayrıca, antimikrobiyal ajanların etkileri, çoklu ilaca dirençli bakterilerle ilişkili tedavilerde başarısızlık göstermektedir. Bu durum, halk sağlığı için küresel bir endişe olma durumuna gelmiştir. Bu yüzden, yeni antimikrobiyal ajanların keşfedilmesi ve antimikrobiyal duyarlılık testlerinin yaygın olarak kullanılması ve geliştirilmesi gerekmektedir. Antimiktobiyal aktivitenin belirlenmesi için birçok teknik bulunmaktadır. Duyarlı mikroorganizmaları inhibe etmek amacıyla uygulanan bu tekniklerden çoğu, katı ya da yarı katı üretim ortamındaki difüzyon ile ilişkili metodlara dayalıdır. Bu teknikler arasında Cross-streak ise yeni antibiyotik keşfi için yapılan araştırmalarda kültürlerin nispeten hızlı bir şekilde taranmasını sağlayan kolay bir tekniktir. Fakat Cross-streak testinin en büyük dezavantajı, niceliksel verilerin elde edilmesindeki güçlüktür. Çünkü inhibisyon bölgesinin kenarları genellikle çok bulanık ve belirsizdir. Bazı antimikrobiyal duyarlılık test teknikleri, bu alandaki dikkat çekici adımlar belirlenerek Clinical Laboratory Standards Institute (CLSI) ve European Committee on Antimicrobial Susceptibility Testing (EUCAST) tarafından standardizasyona tabi tutulmuştur. Bu test prosedürü, spesifik test koşullarının ve metotlarının kullanımına gereksinim duymaktadır. Ayrıca, besiyeri ve inkübasyon koşulları ile zaman bu gereksinimler arasındadır. Hali hazırda kullanılan aktivite belirleme yöntemlerinden Cross-streak yönteminin iyi anlaşılıp geliştirilmesi önem arz etmektedir.

Gungor Karakas
Food waste and loss is an ecological, economic and social problem. The United Nations Food and Agriculture Organization states that approximately one third of all edible foods produced for human consumption are wasted or lost after harvest. The aim of this study is to determine the factors affecting food waste behavior of consumers. In order to reach this aim, a questionnaire was conducted with 583 people in November and December of 2018 in Çorum province. The obtained data were analyzed and explained through Structural Equation Models. As a result of the exploratory factor analysis, a 5-factor structure explaining 76,612% of the total variance was obtained. These factors were named as norm, intention, result awareness, purchasing behavior and planning. These factors were found to have validity, reliability and internal consistency. In addition, it was investigated whether the factors were compatible with the fit indices by means of Confirmatory Factor Analysis. As a result of confirmatory factor analysis, it was determined that the obtained factors met the fit indices values. As a result of Confirmatory Factor Analysis, it was determined that the obtained factors met the fit index values. The effect of the factors on the relationship between each other and the waste behavior were measured by means of the path analysis. As a result of this study, although consumers have positive statements regarding consequence awareness, intent and norms, they have been determined to be unstable in planning and purchasing. Besides, although there was a direct effect of intent and result awareness on waste behavior, it was determined that planning and norms had indirect effects. Considering that the intention is the most influential factor on waste behavior, it should be focused on the activities that will create result awareness in society.
