Possible role of melatonin in the germination of negatively photoblastic and thermosensitive seeds of Phacelia tanacetifolia Benth was studied. Final germination percentage (FGP) was determined in the presence or absence of light at various temperatures, ranging from 0 to 40°C. The highest FGP was determined as 48.7% and 92% at temperature of 15°C in the presence and absence of light, respectively. Seeds were primed with 1% KNO(3) containing various concentrations (0.3, 1, 6, 12, 30, 60, or 90 μM) of melatonin for 2 days at 15°C in darkness. Primed seeds were germinated at an inhibitory temperature of 30°C, and results were compared to those occurring at the optimum temperature of 15°C under both light and no light conditions. Melatonin incorporated into priming medium significantly reversed the inhibitory effects of light and high temperature. Germination was elevated from 2.5% to 52% of FGP for seeds primed in the presence of 6 μM melatonin in darkness at 30°C, while 1 μM melatonin had the highest FGP (21.0%) in the presence of light at 30°C. The highest FGP (47.5%) was obtained from seeds primed in the presence of 0.3 μM melatonin under the light condition at 15°C, while untreated seeds had 1.5% of FGP. The fastest seed germination was determined from seeds primed in the presence of 0.3 μM melatonin (G(50) = 0.56 days) at 15°C in darkness. The possible roles of melatonin in promoting germination parameters of photo- and thermosensitive seed germination are discussed.

This study examines the effects of environmental management practices on environmental knowledge and environmentally responsible behavior by means of an environmental commitment moderator variable regarding the hotel employees in Manavgat–Türkiye. The existing literature on the relevant concepts has provided the theoretical basis of the research. Using the stratified convenience sampling method, a sample of 403 hotel employees from various hotels in the region participated in the survey. First of all, data screening analysis was used for the analysis of research data and the results obtained were analyzed through the AMOS program to test the structural model. According to the research results, it has been determined that environmental management practices are considered to be an important variable in terms of environmental knowledge and environmental knowledge positively affects the level of responsible behavior. In addition, it has been concluded that environmental commitment strengthens the relationship between these variables. In future research, it is predicted that the implementation of this study, which has been applied to hotel employees, in other areas of the tourism sector by taking into account the variables such as organizational commitment, business attachment, organizational performance, and employee attitude will enrich the literature.

Sevoflurane (5%) may be an effective alternative to propofol for induction of anesthesia for ECT.

This study examines the relationship between local food quality perception, dining satisfaction, and post-dining behavioral intention in the context of sustainable gastronomy tourism in Manavgat/Antalya. The research also analyzes the moderator roles of food neophilia and neophobia in this relationship. A face-to-face survey was conducted with the tourists who visited the region and experienced local restaurants. Accordingly, 487 participants were interviewed. In order to analyze the collected data, data survey analysis was applied, and the findings were analyzed using AMOS software (Version 24) to test the structural model. The results have shown that the core perceptions of local food and delivery quality positively affect dining satisfaction, whereas no effect on external quality has been found. Moreover, the findings have also revealed that dining satisfaction positively influences post-dining behavioral intention. In addition, food neophilia and neophobia moderate the relationship between dining satisfaction and post-dining behavioral intention. These findings have emphasized the importance of promoting local food quality to increase tourists’ dining satisfaction and their intention to participate in sustainable gastronomy tourism. Destination managers should collaborate with food producers to create a branded local food line that offers sustainable and delicious options, thereby enhancing the travel experiences of domestic and foreign tourists.

Çok yıllık buğdaygil yem bitkisi türlerinin morfolojik olarak birbirlerine çok benzemeleri, aralarında kolayca melezlenerek hibrit türler oluşturabilmeleri ve doğal varyasyon sebebiyle teşhislerinde ciddi sorunlar yaşanmaktadır. Buna ilave olarak bu türlerde polyploidi çok yaygındır ve aynı türün dahi farklı kromozom sayılarına sahip formları mevcuttur. Bundan dolayı çok yıllık buğdaygil türlerine ait genetik kaynakların bilimsel araştırma ve ıslah çalışmalarında kullanılmadan önce tür teşhislerinin doğru bir şekilde yapılarak ploidi düzeylerinin belirlenmesi zorunludur. Aksi taktirde yapılacak olan melezlemelerde ortaya çıkabilecek genetik uyuşmazlık ve kısırlık gibi sorunlar araştırıcıların zaten kıt olan emek, zaman ve maddi kaynaklarının heba olmasına sebep olmaktadır. Bu çalışmada, ıslah programlarında kullanmak amacıyla Doğu Anadolu Bölgesi dağlık bölgelerinden toplanmış olan 169 buğdaygil yem bitkisi popülasyonunun (Festuca sp., Koeleria sp. ve Agropyron sp.) çekirdek DNA içerikleri flow sitometri yöntemi ile ilk defa belirlenmiş ve popülasyonların ploidi düzeyi ile safiyetlerinin belirlenmesinde kullanılmıştır. Yapılan çekirdek DNA analizi sonuçlarına göre Festuca popülasyonlarında ploidy düzeyi diploid ile octoploid (2n=14, 28, 42, ve 56) arasında değişirken Koeleria popülasyonlarında diploid (2n=14) ile tetraploid (2n=28) arasında değiştiği belirlenmiştir. Bununla birlikte bazı popülasyonların ise saf olmayıp farklı ploidy düzeyine sahip bitkilerden oluştuğu saptanmıştır. Çalışmada incelenen tüm Agropyron popülasyonlarının ise diploid (2n=14) olduğu belirlenmiştir. Çalışmada kullanılan tüm popülasyonlar çekirdek DNA analiz sonuçlarınında yardımıyla taksonomik olarak teşhis edilmiş ve isimlendirilmiştir.
