Sultan Dere | Mehmet Emin Doğan
This study was conducted to investigate the effect of Mn application on the resistance of pepper plants exposed to flood stress. The study was conducted in a climate-controlled room at Siirt University, utilizing the Mazamort three-lobed pepper variety as plant material. In the climate chamber (19 m²), conditions were established at 24±1°C during the day and 18±1°C at night, with a light/dark photoperiod of 16/8 hours. The growing medium consisted of a 2:1 (v) mixture of peat and perlite. Four treatment groups were established: control, flood stress, 2.5 mg/L manganese (Mn), and flood stress combined with 2.5 mg/L Mn. Sixty-day-old Mazamort pepper plants were subjected to continuous flooding and manganese application at each watering. The duration of flood stress was set at 0 days (control) and 10 days. The experiment was designed using a randomized complete block design with three replications, each containing 10 plants. Parameters evaluated at the end of the study included visual assessment, plant height, stem diameter, leaf number, leaf fresh and dry weight, leaf moisture content, root fresh and dry weight, root moisture content, chlorophyll content (SPAD value), ion leakage, relative water content (RWC), and turgor loss. The highest plant height was observed in the 2.5 mg/L manganese treatment (45.82 cm), while the greatest stem diameter was recorded in the control group. The highest leaf number (30.60) and SPAD value (35.34) were also noted in the control group. RWC was highest at 96.90% in the 2.5 mg/L manganese treatment. The maximum turgor loss was 5.606% in the control group, and the highest ion leakage (17.880%) was observed in the 2.5 mg/L manganese treatment. It was concluded that manganese application mitigated the negative effects of flood stress on various parameters; however, it did not fully restore the values to control group levels.

Ayşe Semra Aksoy | Mustafa Yaman | Muhammet Arıcı
Hardaliye, grape-based fermented beverage, rich in antioxidant phenolic compounds. Bioaccessibility and antioxidant capacity of bioactive compounds in hardaliye, produced using varying amounts of mustard seeds (1%, 1.5%, and 2%) with Merlot and Papazkarası grape varieties, were evaluated under in vitro gastrointestinal digestion conditions. After digestion, Merlot and Papazkarası samples with 2% addition of mustard seed showed significantly higher total phenolic compounds (TPC) (358.48±14.73 and 89.01±2.42 mg GAE/L, respectively) compared to other samples (P<0.05). 2% mustard seed added Merlot samples resulted in the highest 1,1-diphenyl-2-picrylhydrazyl (DPPH) and cupric reducing antioxidant capacity (CUPRAC) values (19.06±3.91 and 9.96±1.83 mmol TEAC/L, respectively) which differed significantly from other samples (P<0.05). The Merlot sample with 2% addition of mustard seed showed significantly higher TPC, total flavonoid compounds (TFC), DPPH, and CUPRAC bioaccessibility values compared to other Merlot samples (P<0.05). For Papazkarası samples with 2% mustard seed addition, significant differences were observed only in terms of TPC and TFC bioaccessibility values (15.87±2.30% and 15.27±1.29%, respectively) compared to samples with 1% and 1.5% mustard seed addition (P<0.05). The study demonstrated that the bioaccessibility of bioactive compounds in hardaliye can vary depending on the grape variety and to some extent, the use of mustard seed. This suggests that the food matrix and interaction with other food matrices in the environment can affect the stability and bioavailability of bioactive compounds during simulated digestion.

Şevket Evci
Studies on colic, an economically important metabolic disease in horses, have typically emphasized maintenance characteristics. However, recent research has demonstrated that nutrient content also contributes to the development of colic. Microbial fermentation of the diet begins in the stomach and continues through the hindgut. During this process, various substrates are produced, including acetate, propionate, butyrate, and methane. The gut contains bacteria such as Firmicutes and Bacteroidetes, but the dominance of one over the other is influenced by the type of substrate available in the gut, such as oat, barley, wheat, corn, etc. Microbial fermentation in the equine cecum is markedly influenced by the pH balance of the nutrient metabolism. This has varying impacts on the cecal microbiota. Investigations into the effects of different feeding methods and nutrients have yielded diverse outcomes for the etiology of colic and post-colic nutrition. The objective of this review is to assess the impact of nutrition and diet composition on the etiology of colic in horses, investigate the role of additives in preventing colic cases, and analyze the results of several studies.

The objective of this study was to ascertain the impact of ultrasound application on the probiotic characteristics and antioxidant activity of yeasts. In this context, the pH changes, probiotic properties and antioxidant activities of K. marxianus (Km), S. boulardii (Sb) and S. cerevisiae (Sc) were determined by ultrasound application at different durations (5, 15, 30 and 60 minutes at 24 kHz). The lowest pH values were determined for cultures of Km (ultrasound non-applied K. marxianus), Sb-30 (30 min. ultrasound applied S. boulardii) and Sc-5 (5 min. ultrasound applied S. cerevisiae) as 4.48, 5.15 and 5.26, respectively. The hydrophobicity values of the yeast strains varied between 6% and 24%, increased with ultrasound application. Although S. boulardii had the highest tolerance to low pH and bile salts, the resistance of all yeast to low pH and bile salts decreased with ultrasound application. K. marxianus had the least survival under in vitro conditions, but ultrasound application increased survival of K. marxianus strains and slightly affected the survival rate of S. boulardii and S. cerevisiae. Increasing of duration time of ultrasound application resulted higher antioxidant activity and so the highest antioxidant activity was determined for Sb-60. Finally, ultrasound application could be used for the development of hydrophobicity and antioxidant properties of yeast cultures.

Rosero, Olga Lucía
COMPENDIO Se estudió el efecto prebiótico del derivado de la lactosa (DL) en la población microbiana presente en las muestras de heces (inóculo fecal) de los cerdos posdestete. Se utilizó la técnica de producción de gas in vitro en 2 sustratos: el control pulpa de remolacha (PR) y DL. Se desarrollaron dos etapas. En la primera se determinó la producción del gas y las proporciones de ácidos grasos volátiles (AGV), evaluando la actividad microbiana en los niveles (0, 0.2, 2, 20 y 100%) de DL reemplazando a la PR, durante la fermentación de 144h. El tiempo medio de la producción del gas potencial se alcanzó a las 12h de la fermentación. Este tiempo se utilizó para la segunda etapa con tres niveles de DL (0, 20 y 100%). Se determinó el efecto del DL sobre la composición de la población microbiana (E. coli, lactobacillus y anaerobios facultativos totales), concentración de AGV y sobre el pH, como resultado de la fermentación bacteriana . Se incrementó la concentración del butirato (P < 0.001) y la acidificación (P < 0.001) del medio. El DL modificó la composición microbiana, que se reflejó en la disminución (P < 0.001) del número de colonias microbianas de E. coli. En conclusión el DL en niveles altos presentó efectos prebióticos.

Güvenilir gıdaya sürdürülebilir koşullarda ulaşılabilmesi için değişen dünya ve çevre koşullarında tarımsal üretim yapılması, teknolojik ve mekanizasyon kullanımını daha önemli hale getirmiştir. Bu çalışmada Şırnak ilinin tarımsal mekanizasyon düzeyi araştırılarak Türkiye ortalaması ile karşılaştırılmıştır. Türkiye İstatistik Kurumu istatistiki verilerine dayanarak traktör sayısı, tarım alet ve makineleri sayısı ile tarımsal mekanizasyon düzeyi göstergeleri hesaplanarak özetlenmiştir. 2012-2022 yılları arasında Şırnak ili ortalama mekanizasyon verilerine göre, kullanılan tarım alanlarında %12, traktör güç değerlerinde %16 oranında artış gerçekleşmiştir. Birim alana düşen güç 0,66 kW ha-1, 1000 ha alana düşen traktör sayısı 18,72 olmuştur. Bir traktöre düşen toplam alan 53,43 ha olurken, traktör başına düşen alet makine sayısı 3,78 olarak bulunmuştur. Şırnak ilçeleri arasında mekanizasyon düzeyi yönünden en iyi sonuçları Cizre ilçesi verirken, Uludere ve Beytüşşebap ilçeleri düşük mekanizasyon değerlerine sahip verileri ile sonuçlanmıştır. Ayrıca Şırnak ili mekanizasyon verileri, bölge illeri ile benzer mekanizasyon sonuçları vermiştir. Ortalama traktör güç değeri 47,03 kW olarak, Türkiye ortalamasından daha yüksek sonuçlar oluştururken, diğer mekanizasyon parametreleri bakımından düşük mekanizasyon sonuçlarına sahiptir. İki ülkeye sınırı bulunan ilin tarımsal potansiyelini arttırmak için mekanizasyon düzeyinin en kısa sürede yükseltilerek işletme refah seviyesi arttırılmalı ve bölge kalkınması desteklenmelidir.

Muhsin Yıldız | Çeknas Erdinç | Aytekin Ekincialp
Kuraklık stresi, pek çok kültür bitkisinde olduğu gibi taze fasulye üretimini de sınırlayan başlıca faktörlerden biridir. Son zamanlarda düşük dozda gama ışını uygulamalarının bitki gelişiminin kritik aşamalarında kuraklığın oluşturduğu olumsuz etkinin elemine edilmesinde yardımcı olduğu bazı araştırmacılar tarafından bildirilmiştir. Fakat bu konuda yapılan çalışmalar oldukça sınırlıdır. Bu çalışmada farklı gama ışın dozları (0, 25, 50 ve 100 Gy) uygulanan Gina ve Romano taze fasulye çeşitlerinde kısıtlı sulamanın etkilerinin belirlenmesi amaçlanmıştır. Fideler iklim odası koşullarında 23 ± 2°C sıcaklık ve 16:8 ışık:karanlık periyodunda tam sulama [%100 (I1)] ve kısıtlı sulama [%50 (I2)] olacak şekilde iki farklı sulama seviyesinde yetiştirilmişlerdir. Çalışma sonunda gama ışını dozları ile kısıtlı sulamanın sürgün ve kök boyu, yaprak sayısı, sürgün ve kök yaş-kuru ağırlıkları, kök-sürgün oranı gibi fide gelişim parametrelerinin yanı sıra yaprak oransal su içeriği, fotosentetik pigment içeriği, lipid peroksidasyonu ve sürgün besin elementi içeriklerine etkisi araştırılmıştır. Çalışmada düşük doz gama uygulamasının kısıtlı sulama koşullarında çeşitlere göre farklı sonuçlar verdiği görülmüştür. Gama ışın dozları %50 sulamada Gina çeşidinde kök boyunda önemli bir etki yaratırken, Romano çeşidinde 50 ve 100 Gy dozlarının sürgün boyu ile yaş ve kuru ağırlıklarda önemli bir artış sağlamıştır. MDA içeriği her iki çeşitte de su stresinde 50 ve 100 Gy gama ışını ile birlikte önemli miktarda azalmıştır. Düşük doz gama ışını uygulamasının özellikle Romano çeşidinde daha etkili olduğu ve genel olarak 50 ve 100 Gy gama ışın dozlarının kısıtlı sulamada uygulanabilir dozlar olduğu belirlenmiştir.

Ebru Sevinç | Nuray Özer
This study investigates the reactions of four summer pumpkin cultivars (cvs. Çağlayan, Mert Bey, Sena Hanım, TG38) to root and crown rot caused by Fusarium proliferatum by taking into account criteria such as disease severity, plant growth (number of leaves, height, dry and fresh weight of shoot) and the accumulation of phenolic compounds in the roots. Seeds of each cultivar were inoculated with the pathogen and left to develop for 1 month at 25oC in a controlled climate room. The content of phenolic compounds in ethanolic root extracts was determined using high-performance liquid chromatography (HPLC). Cv. Sena Hanım had the lowest disease severity (4.40%) among the cultivars, followed by cvs. Çağlayan (10.62%) and Mert Bey (11.07%). Plants developed from inoculated seeds of cvs. Çağlayan and Sena Hanım had no decrease in the number of leaves and in length, fresh and dry weight of shoots in comparison to the control (plants from non-inoculated seeds), while cv. Mert Bey demonstrated a decrease at very low rates in shoot fresh and dry weight (2.24% and 0.77%, respectively). The phenolic compound that exhibited the highest increase in root extracts of cv. Sena Hanım compared to the control among the cultivars was p-coumaric acid (6.57-fold). This study demonstrates that p-coumaric acid can play an important role in the resistance of pumpkin to seed infestation by F. proliferatum.
