Çalışmanın amacı Çekişte çeşidi zeytinlerden elde edilen zeytinyağlarının ısıtma işlemi sırasında temel kalite kriterleri, oksidatif stabilite ve yağ asidi bileşiminde meydana gelen değişimlerin belirlenmesidir. Bu amaçla Aydın ilinden 2017 yılında hasat edilmiş olan Çekişte çeşidi zeytinlerden elde edilmiş olan zeytinyağı, 100°C sıcaklıkta ve 20 L/saat hava akışı altında toplamda 50 saat süreyle ısıtılmıştır ve 10 saatlik aralıklarla serbest yağ asidi oranı, peroksit sayısı, dien ve trien (K232 ve K270) değerleri, toplam fenol miktarı, antioksidan aktivite, klorofil ve karotenoid miktarları ile yağ asidi kompozisyonları yönünden analiz edilmiştir. Ayrıca örneklerin indüksiyon periyodu olarak ifade edilen oksidatif stabiliteleri belirlenmiştir. Çalışma sonunda temel kalite parametrelerinden serbest yağ asidi miktarı, peroksit sayısı, dien ve trien (K232 ve K270) değerlerinin ısıtma işlemi ile birlikte artış gösterdiği saptanmıştır. Örneklerin toplam fenol, antioksidan aktivite, klorofil ve karotenoid miktarları ise ısıtma süresinin artmasıyla birlikte kademeli olarak azalmıştır. Benzer şekilde indüksiyon periyodunun da işlem süresinin artmasıyla birlikte azaldığı tespit edilmiştir. Zeytinyağı örneklerinde tespit edilen yağ asitlerinden linolenik asit miktarının ise işlem sonunda önemli düzeyde arttığı, oleik asit miktarının ise işlem öncesine göre azalma eğiliminde olduğu saptanmıştır.

Agricultural production and income are important for Mediterranean region of Turkey. The region and especially Antalya province is well-known with greenhouse production. For greenhouse production achieving sustainability is important for meeting domestic and foreign demand and security of production lands. In order to measure the potential for improving greenhouse operators 281 farmers were surveyed in 2015 in Antalya and profit inefficiency and factors affecting inefficiencies of operators were estimated using stochastic frontier approach. Accordingly, the average inefficiency level of operators was found as 57 %, signifying the potential for improvement. The main objective was to undermine the impact of landownership on this inefficiency level. Yet, the impact of other relevant factors referring to greenhouse structures and famers’ characteristics were estimated as well. While level of education seemed to reduce inefficiency, household size had appeared as an inefficiency rising factor referring to professional labour endowment of greenhouse production in Antalya. Being renter of land appeared as an inefficiency rising factor as well as holding plastic house or having located in the western parts of Antalya. These findings indicated importance of supporting improved production technologies and use of strengthened structures. In addition, it appeared as essential to provide incentives to renters to cope with their costs.

İşgücü kavramı, kişilerin veya tüzel kişiliklerin ekonomik faaliyetleri ile birlikte ortaya çıkmıştır. Bir malın veya hizmetin üretimi karşılıklı iş ilişkisine bağlı olarak yürütülmektedir. Özellikle sanayi devrimi sonucunda ortaya çıkan işçi sınıfı ile birlikte işçilerin ve işverenlerin hak ile yükümlülükleri konusunda hukuki kurallara ihtiyaç duyulmaya başlanmıştır. Temelde sanayi ağırlıklı olan bu hukuki düzenlemeler tarım sektörünü çoğunlukla kapsam dışı bırakmıştır. Tarım işletmelerinin aile işgücüne dayalı bir yapısı olduğu için, dışarıdan mal ve hizmet alımı konusunda iş sözleşmesi düzenlenmesi diğer sektörlere oranla daha azdır. Tarım sektöründe kurumsallaşmanın yaygın olmaması, tarım işçisi sınıfının olmaması, kendi hesabına çalışan aile işletmelerinin yoğun olması, gibi nedenler gelişmekte olan Türkiye gibi ülkelerde tarımsal iş hukukunun sadece iş hukukunun bir yan dalı olarak kalmasına yol açmıştır. Çalışmaya konu olan Kuzey Amerika ülkelerinde, özellikle Amerika ve Kanada’da, tarımsal iş hukuku yasal sistem içerisinde özel bir hukuk dalı olarak yer almaktadır. Amerika ve Kanada federal bir yönetim sistemi ile yönetilmekte olup, her eyaletin genel yasal çerçeve yanında özel düzenlemeleri de bulunmaktadır. Çalışmanın amacı, Kuzey Amerika ülkelerinden Amerika ve Kanada’da tarımsal iş hukuku konusunda gelişmelerle Türkiye’yi karşılaştırmaktır. Bu kapsamda Amerika ve Kanada’da tarımsal ücretler, mevsimlik ve göçmen işçiler, çocuk işçi ile sosyal güvence ve iş sağlığı konularındaki yasal düzenlemeler incelenmiş ve Türkiye’nin mevcut yasal mevzuatı ile birlikte değerlendirilmiştir.

Chronic diseases progress slowly and generally cause symptoms in middle age onward. It is widely known that there is a close link between diets and chronic diseases in human. Foods which have specific target functions and preventive impacts on human health as well as their basic nutritional effects are defined as functional foods. These foods may decrease risk for chronic diseases due to having health preventive impacts on human health. Milk is an useful baverage for during childhood and adolescence because of its macro and micro nutrients. Milk composition is affected by mainly genetic, nutrition, season, lactation stage etc. Therefore, there are some differences in milk components between organic and conventional milk because of especially heredities of herds and nutrition. Seasonal variations in pasture, amount of grains and forages (fresh or conserved) cause changes in milk fatty acid composition of organic and conventional milk. Furthermore, organic production regulations limit the use of starch-based concentrates and supplements; therefore, some nutrients’ concentrations (protein, thiamine, vitamin B1 and B2, I etc) in organic milk may be expected to be lower than those of conventional milk. In this paper, organic and conventional milk components have been reviewed in term of functional milk.

Organik ürünler genellikle tam olgun veya olgunlaşmaya yakın hasat edilirler, bu nedenle kalitelerinin yüksek olmasına karşın raf ömürleri daha kısa ve yola dayanım güçleri daha azdır. Hasat olgunluğu dışında, hasat öncesi bahçede yapılan kültürel uygulamalar organik meyve ve sebzelerin tadını, besin değerini ve raf ömrünü belirler. Ancak elde edilen yüksek kalitenin tüketiciye ulaşıncaya kadar korunması çok önemlidir. Kolay bozulabilir organik bahçe ürünlerinin kalitelerinin korunması hasat sonrası uygulamalara bağlıdır. Meyve, sebze ve çiçeklerin kalitelerinin korunması ve % 40’lara ulaşan hasat sonrası kayıpların önlenmesi için hasat sonrası fizyolojilerinin ve isteklerinin dikkate alınması gereklidir. Canlılığı hasattan sonra devam eden ürünün metabolizmasını yavaşlatma ve ömrünü uzatmada en önemli faktör sıcaklıktır. Hasat edilen ürünün yüksek sıcaklıklardan korunması, hemen soğutulması ve tüketiciye ulaşıncaya kadar soğuk zincirin kırılmaması gerekir. Sıcaklık dışında oransal nemi kontrol etmek, ürünü özenle paketlemek, yaralanmaya yol açmamak hastalık gelişimini de önler. Bu önlemler, hasat sonrası teknolojisinin sınırlı olduğu organik ürünler açısından daha da önemlidir. Sertifikalı organik ürünler için izin verilen hasat sonrası uygulamaların ele alındığı bu bildiride, organik bahçe ürünlerinde kalitenin korunmasında etkili olan faktörler, depolama ve soğutma yöntemleri, temizlik ürünleri ve dezenfektanlar, etilen ve kontrolü ile hasat sonrası çevreyle barışık diğer uygulamalara yer verilmiştir.

Turkey, which is among the major gene centers of the world and has a special place in plant genetic diversity. However, many plant genetic resources, including geophytes, are under genetic erosion because of the environmental and other problems and therefore face with the danger of extinction. Lilium ciliatum is endemic to North East Anatolia. IUCN (International Union for the Conservation of Natural Resources) Red List Category of this species is Endangered (EN). Lilium ciliatum naturally grown in Zigana pass, Bayburt, Trabzon, Bulancak, Giresun and Gümüşhane is endangered and major threats of L. ciliatum are road construction and human disturbance related to ecotourism and recreation. It was reported that Lilium carniolicum naturally grown in Turkey is endangered although it isn’t in the IUCN Red List. Distribution areas of L. carniolicum are Trabzon, Rize, Artvin and it is also endemic to North East Anatolia. These species have high potential for use as ornamental plants with their colorful big flowers. In addition, the bulbs of these species are also used in the cosmetic industry and medicine. These are the main properties that increase the importance of L. ciliatum and L. carniolicum species. Therefore it is very important to protect the habitats of these species, ensure the continuity of their generations. The disappearance of these endemic species from our country means to disappear from the world. This review has been given in order to give some information about the endangered Lilium species of Turkey and conservation actions on these species in Turkey flora and take attention to the issue.

Genetic diversity estimation among different species is an important tool for genetic improvement to maximize the yield, desirable quality, wider adaptation, pest and insect resistance that ultimately boosting traditional plant breeding methods. The most efficient way of diversity estimation is application of molecular markers. In this study, twenty random amplified polymorphic DNA (RAPD) primers were utilized to estimate the genetic diversity between ten sunflower genotypes. Overall 227 bands were amplified by 20 primers with an average of 11.35 bands per primer. RAPD data showed 86.34% polymorophic bands and 13.65% of monomorophic bands. Genetic similarity was ranged from 50.22% to 87.22%. The lowest similarity (50.22%) was observed between FH-352 and FH-359 and the maximum similarity 87.22% was observed between A-23 and G-46. Polymorphic information content (PIC) values were varying from 0.05 to 0.12 with a mean of 0.09. Cluster analysis based on RAPD results displayed two major distinct groups 1 and 2. Group-2 contains FH-352 which was the most diverse genotype, while group-1 consists of few sub groups with all other genotypes. Ample diversity was found in all the genotypes. Present study reveals novel information about sunflower genome which can be used in future studies for sunflower improvement.

The purpose of this study is to compare innovative technology usage levels of dairy farms, supported and non-supported by The Instrument for Pre-accession Assistance-Rural Development (IPARD) program, by scoring their usage level of 10 innovative technologies in their dairy farms. Another purpose of the study is to determine the factors associated with the innovative technology usage levels of dairy farms. The main material of the study is dairy farms supported and not supported by the IPARD program in Konya. Full count sampling method was used when determining the dairy farms supported by IPARD Program and Neyman allocation sampling method was used when determining the dairy farm non-supported by IPARD program. Research data were collected from 50 dairy farms supported by IPARD program and 100 dairy farms non-supported by IPARD program by administering a questionnaire filled during the face-to-face interviews conducted with each individual respondent. As a result of the study, it was determined that the average gross production values and gross profits of dairy farms supported by IPARD program were 4 times higher than those non-supported by IPARD program. While innovative technology usage level of dairy farms non-supported by IPARD program were entirely low level, 90% of dairy farms supported by IPARD program were high level. From the point of view of dairy farm scale, it was determined that innovative technology usage levels were high (69.84%) in dairy farms that had 51 and more milking cows. As a result of chi-square independence test, statistically significant relationship was found between innovative technology usage level of dairy farm and 12 of 13 factors.
