The aim of this study was to determine the yield and various quality characteristics of two different strawberry cultivars (Fragaria x ananassa var. Festival and Camarosa), grown in the ecological conditions of Sultanhisar, Aydın, Turkey. The study was conducted over two years, in ten randomly selected open grown plantations for each of the two cultivars. When the fruits reached harvest maturity, they were harvested and their yield values, mean fruit weight, fruit diameter, fruit length, fruit firmness, colour, pH, titrable acidity, water-soluble dry matter, vitamin C content, total antioxidant capacity and total phenolics were determined. According to the results obtained, yield values fell in the second year of the study, but mean fruit weight, diameter and length increased. Similarly, the fruit firmness of both varieties was considerably greater in the second year, and these differences between the years were found to be statistically significant. While the highest antioxidant capacity and phenolic content were obtained from the Festival cultivar, the highest vitamin C content was found in the Camarosa cultivar. The changes of total antioxidant capacity and the amount of total phenolics according to years of both varieties were found to be statistically significant.

Drought stress is one of the most serious abiotic stresses that cause a reduction in plant growth, development and yield in the world. The aim of this study is to reveal the morphological, physiological and biochemical responses of the Demre pepper variety and nine different pepper genotypes against drought stress. Pepper seeds were planted into trays containing peat: perlite (2: 1) mixture. Then, seedlings having two leaves were transferred to plastic pots containing mixture of peat:perlite (2:1) mixture. Drought stress application was started when the plants have four leaves. The control plants were irrigated with nutrition solution. Genotypes were classified according to the severity of leaf damage symptoms by using 0-5 scale. In addition, shoot fresh and dry weight, plant height, stem diameter, leaf number, leaf area, relative water content (RWC), membrane injury index (MII), potassium (K) and calcium (Ca) concentration of shoot, malondialdehyde content (MDA), total chlorophyll and carotenoid, total flavonoid and phenolic content, anitoxidative enzyme activities (superoxide dismutase (SOD), catalase (CAT), glutathione reductase (GR), ascorbate peroxidase (APX)) were also determined. As a result of the study, it was determined that drought had negative effect in terms of morphological and physiological parameters, and this effect revealed differences among genotypes. While drought stress increased MDA and antioxidative enzyme activity, BIB-6 and BIB-8 genotypes were found to be the most tolerant genotypes among the genotypes examined.

According to FAOSTAT 2017 data, Turkey located ranks second after China in terms of world honey production and ranks third in terms of the number of colonies. According to Turkish Statistical Institute (TURKSTAT) 2018 data, Turkey had 7.904.502 colonies and total honey production of 107.920 tons while the average honey yield was calculated 13.7 kg per colony. It is economically important that informing to beekeepers and policymakers the expected change in the number of colonies and honey yield in the next years. This study aims to estimate the production values for the next 5 years by using the number of colonies and honey yields of the past years. For this purpose, the next five years (2019-2023) forecast has been made by using data from the last 50 years (1969-2018). ARIMA (1,1,0) first-degree autoregressive time series model was used for the number of colonies and honey yields from the data obtained from TURKSTAT and FAOSTAT. SPSS package program was used for forecasting. According to the results, compared to 2018 an increase of 1.3% and 7.4% is expected in the number of colonies between 2019 and 2023. In addition, the honey yield is expected to increase between 2.77% and 3.12% compared to 2018. It seems that increasing the number of colonies and expecting a less increase in honey yield per colony will increase the production costs in the next years. Hence, consumers will consume honey and honeybee products at a higher price. It can be suggested that, beekeepers should take care about increasing the number of colonies as well as increase the honey yield per colony to beekeeping economy, consumers and the economy of the country.

İşgücü, nüfusun üretimde etkin olan bölümüdür. Nüfustaki gelişmelere bağlı olarak oluşan toplam işgücü arzı ve ekonomik koşullara göre şekillenen işgücü talebi; piyasa oluşumunun iki temel unsurudur. İşgücü piyasaları; arz ve talebinin karşılaştığı, ücretin oluştuğu sosyal bir organizasyon olarak tanımlanabilir. Tüm piyasa yapıları içerisinde işgücü piyasası; işleyişi ve özellikleri nedeniyle ekonominin diğer birimlerinden önemli ölçüde etkilenen ve bunları yüksek oranda etkileyen konumdadır. Bu nedenle üretim sürecinde ve planlamasında işgücü piyasalarının detaylı analiz edilmesi gerekmektedir. İşgücü piyasaları içerisinde; ekonominin temelini oluşturan ve diğer piyasalara çeşitli kaynaklardan katkı sağlayan tarımsal işgücü piyasasının analiz edilmesine ihtiyaç duyulmaktadır. Çünkü tarım sektöründeki doğal kaynakların ve sermaye unsurlarının kullanımında doğrudan işgücünün katkısının olması, diğer sektörlere kıyasla tarımsal faaliyetlerde işgücünün birim alanda daha yoğun kullanılması, tarım sektöründen diğer sektörlere işgücü transferlerinin gerçekleştirilmesi, tarımsal işgücünün gizli işsizlik ve yapısal işsizliğin kaynağını oluşturması gibi nedenlerle tarımsal işgücünün incelenmesi ve sınıflandırılması gerekmektedir. Ayrıca kamu kurum/kuruluşları için veri oluşumunda kullanılacak işgücü çeşitlerini belirlemek, güvenilir istatistiki verilerin elde edilmesine katkıda bulunarak planlanan projelerde ve oluşturulacak politikalarda doğru karar süreçlerine erişimi kolaylaştırmak amacıyla tarım sektöründe işgücünün sınıflandırılması gerekmektedir. Belirlenen amaçlar doğrultusunda tarım sektöründeki işgücü çeşitlerinin belirlenmesi, yapılan kavramsal tanımlamaların bir araya getirilmesi ve literatürde anlamsal bütünlüğün sağlanmasına yönelik olarak bu çalışma gerçekleştirilmiştir.

İsmail Tontul
The increase in consumers' demands for safer and healthier food has led to the development of many new products in food technology. For this reason, micro- or nanoencapsulation has become an important area in order to protect food components with functional properties against environmental conditions and to provide controlled release in recent years. As a matter of fact, many encapsulation techniques have been developed and many different active materials have been encapsulated. Nanoemulsions, a nanoencapsulation technique, are the process of encapsulating core material in two immiscible liquids. Nanoemulsions have higher stability and loading capacity compared to normal emulsions. It also increases the bioavailability of the core materials because of the increased absorption of the active material in the digestive tract. In this review, the required materials for nanoemulsion preparation, the nanoemulsification methods, and the studies on the encapsulation of various food components in nanoemulsions have been reviewed.

The major antimicrobial proteins in donkey milk are lysozyme, lactoferrin, lactoperoxidase and immunoglobulins. Lysozyme has an important role in the host defense by way it inhibits the pathogenic bacteria. The aim of this study is to investigate the Lysozyme (LYZ) gene polymorphism in 82 donkeys reared in Thrace region of Turkey. 716 bp long partial 5’ UTR, exon 1, intron 1, exon 2 regions of LYZ gene were amplified and PCR products were analyzed via DNA sequencing. Three novel single nucleotide polymorphisms (SNPs) were identified as g.1782775A>G, g.1782924A>G and g.1782960T>C in the first intron of LYZ gene. The partial DNA sequence of LYZ gene in donkeys was reported in the present study and sequences of LYZ were entered to NCBI Genbank database with the accession number: MK984689-MK984692. This SNP may have an effect on immune system and milk traits in donkeys and additional studies are needed to confirm this assumption for donkey breeding.
