Pomegranate has been recently considered as a significant fruit for human health and demanded year-long apart from two-month standard harvest period. To extend market supply durations over longer periods, various methods and treatments should be applied to pomegranates to preserve quality parameters throughout different storage durations. The present study was conducted at cold storages of ÇOMÜ Agricultural Faculty to investigate the effects of 1-Methylcyclopropane (1-MCP) and MAP (LDPE, 20 mµ) treatments on quality attributes of ‘Hicaz’ pomegranate cultivar. Experimental materials were treated with two different doses (625 and 1250 ppb) of 1-MCP alone and combined with MAP (625 ppb + MAP and 1250 ppb + MAP) and stored at 3 different storage durations (40, 80 and 120 days). All fruits, including control group, were stored at 6.5-7.5°C temperature and 85-90% relative humidity. At the end of each storage period, fruits were subjected to weight loss (%), Total soluble solids (TSS) content (%), titratable total acidity (TTA) (%g), pH, grain color (a value), decay ratio (%) analyses and assessments were performed for these quality and biochemical characteristics. Both Doses of 1-MCP alone and combined with MAP treatments were found to be more efficient in decelerating the adverse effects on rotting, perishes and other quality parameters, however there were not significant differences between two doses of 1-MCP. Therefore, MAP or 625 ppb 1-MCP treatments alone or combined with MAP treatments can be recommended for better preservation of quality parameter throughout the storage of pomegranates.

Effects of two dietary levels of starch and crude protein on performance of dairy cow fed low roughage level (70:30 concentrate to roughage) were investigated. Twenty eight Holstein cows were randomly assigned to one of four dietary treatments in a 2 x 2 factorial arrangement. Factors were two dietary level of starch (14% and 22%) and crude protein (15% and 18%). Wheat straw was used as sole roughage source. The study was continued 6 weeks. Dry matter intake was not affected (P>0.05) by the dietary treatments in the study. Milk and protein yield (kg/d) were higher (P

Phosphates are widely used as food additives in meat products to increase the water-holding capacity, reduce the cooking loss and improve the textural properties. Furthermore, phosphates protect aroma and accelerate the formation of cured meat color as well as having antioxidant and antimicrobial effects. Many research about using phosphates in meat products showed that increasing chain length of phosphates improves antioxidant and antimicrobial effects. It has been stated that vacuum or modified atmosphere packaging, the use of phosphates with natural antioxidants and encapsulation of phosphates are useful approaches to enhance the antioxidant effects of phosphates. It has been reported that irradiation, vacuum or modified atmosphere packaging, storage at low temperature and the use of the salt provide strong synergistic effect on the antimicrobial properties of phosphates. In this review, researches about antioxidant and antimicrobial properties of phosphates and suggestions for the meat industry about industrial applications of phosphates are presented.

In this study the effects of dried apricot pomace (AP) on the technological, nutritional and sensory quality of frankfurters were investigated. Frankfurters formulated with 5% AP showed better quality compared to the addition of 10 and 15% AP. Protein and fat content decreased as the concentration of added AP was over 5%. AP addition resulted in lower pH and energy values. Frankfurters formulated with AP had higher cooking and process yield values. AP addition resulted with decrement in lightness and increment in yellowness of samples. 5% addition of AP resulted in good sensory scores. The results indicate that apricot pomace could be an effective functional ingredient in emulsion type meat products.

Yield and quality performances of 27 soybean cultivars were evaluated in two years field experiment between 2015 and 2016 at the Experimental Farm of Faculty of Agricultural Sciences and Technologies, Nigde Omer Halisdemir University, Nigde, located in the Central Anatolia Region. The field experiments were laid out in the randomized complete block design with three replications in each year. The main phenological stages of development such as time to emergence, flowering, time to pod formation and time to maturity were determined as calendar days. Plant height, the first pod height, numbers of branch, pod and seed per plant, number of seed per pod, 100-seed weight, protein content, oil content and seed yield per decar were determined as yield and quality parameters. The results of two-year study revealed that the soybean cultivars differed significantly for all characters studied under Nigde conditions. It was also observed that yield and quality performances of cultivars fluctuated in years. Average seed yield values of cultivars were ranged from 135.2 kg/da-1 (Inton-I. maturity group) to 295.8 kg/da-1 (Adasoy-IV maturity group) in 2015 and 2016. In two years mean, the cultivars Adasoy, Sa-88 and Nova were determined as the most promising genotypes for main crop production in Nigde conditions.

Ecological processes that occur in a lake depend on the physico-chemical (abiotic) and biotic factors of the system and the interrelations between them. It can be concluded that the current nutrient loadings from both point and non-point sources are cause to increase eutrophic case over the years. This study indicate that the sustainable utilization of reservoir in combination with proper wastewater treatment plant and controlled use of pesticides has a potential to reduce the current nutrient loadings into Suat Uğurlu Lake. The estimated nutrient reductions that could be achieved from the management scenario would be enough to revert the lake from mesotrophic situation to trophic state. The reduction of nutrient loadings into Suat Uğurlu Lake could be achieved through the practice of Integrated Water Resource Management (IWRM), through good management. However, as long as pertinent issues of urban poverty, watershed management and public awareness and involvement in water related issues are not addressed, trophic in Suat Uğurlu Lake will remain a problem.

Temel mikro-besin elementi demir (Fe) bitkide önemli rolleri bulunan birçok metalloproteinin aktif bölgesinde kofaktör olarak yer alır. Öte yandan aşırı reaktif olduğundan, hücre içerisinde fazla birikimi reaktif oksijen türlerinin üretimini tetikleyerek hücre ölümlerine neden olur. Dolayısıyla hücre içerisindeki demir homeostazı bitki gelişimi için çok önemlidir. Bitkiler demiri kök içerisine aldıktan sonra hücre içi kompartmanlara dağıtımını yaparlar. Hücre içi demir taşınımı ve dolayısıyla hücresel demir homeostazı farklı membran protein ailelerinin senkronize kontrolü sayesinde yürütülmektedir. Bu membran proteinlerinin demir eksikliği altında ifade seviyelerinin arttığı keşfedilmiştir. Bu taşıyıcıların görev ve regülasyonlarının irdelenmesi bitkilerdeki demir alım ve dağıtım mekanizmalarının anlaşılması açısından çok önemlidir. Bu yüzden bu derlemede hücre içerisine alınan demirin organellere dağıtımından sorumlu taşıyıcılar ile bu taşıyıcılar hakkındaki güncel gelişmelerden bahsedilmektedir.

Organik hayvansal üretim, hayvanların fizyolojik ihtiyaçlarına uygun bakım ve besleme yöntemlerinin uygulandığı, gerektiğinde alternatif ilaç ve tedaviye öncelik verilerek hayvan sağlığının korunduğu doğal bir yetiştirme sistemidir. Hayvan yetiştiriciliğinde kullanılan antibiyotik ve antiparaziter ilaçlara karşı dirençli suşların giderek artması, hayvansal ürünlerde ilaç kalıntılarının meydana gelmesi ve bu ürünleri tüketen insanlarda önemli sağlık problemlerine yol açması alternatif bitkisel çözüm arayışlarını beraberinde getirmiştir. Bu çalışmada, Orta Anadolu Bölgesi halk veteriner hekimliği özelinde kullanılan bitkisel drogların organik hayvansal üretimde tedavi ve koruyucu etkilerinin değerlendirilmesi amaçlandı. Çalışmanın materyalini, Orta Anadolu Bölgesi’ndeki (Çankırı, Kayseri, Kırıkkale, Kırşehir, Yozgat) hayvan yetiştiricilerinden elde edilen yazılı, sözlü ve görsel veriler oluşturdu. Çalışmada, sığır, koyun, at, tavuk, arı ve köpek türlerinde görülen iç hastalıkları, cerrahi hastalıklar, doğum ve jinekolojik sorunlar ve paraziter hastalıklarda tedavi amacıyla 30 bitkisel drogun kullanıldığı tespit edildi. Organik hayvancılıkta başta antibiyotikler olmak üzere her türlü sentetik ilaç kullanımının yasaklandığı ya da sınırlandığı değerlendirildiğinde, sürü sağlığının korunması ve tedavisinde bu maddelerin yerine doğal olan bitkisel drogların tercih edilmesinin olumlu katkılar sağlayacağı ileri sürülebilir.
