Orange Peel and Cauliflower Residues Supplementation Induce Morphological and Physiological Tolerance in Common Bean under Drought Stress Full text
2023
İlkay Yavaş | Elif Sude Çiçek
Drought is one of the most harmful abiotic stresses affecting the development and yield of the common bean (Phaseolus vulgaris L.). The current climate change and the resulting increased drought will worsen the negative impact of water stress on the plant. The powder of orange peel and cauliflower waste were added as soil supplementation at rates of 7 and 15 g/pot to pots of Phaseolus vulgaris L. under different drought conditions. The growth and physiological analysis were estimated after flowering period of common bean. In the pots where drought will be applied, irrigation was stopped for 2, 4, 6, 8 and 10 days during the flowering period and irrigation was performed again after water stress application. To measure moisture percentage of pots, first dry pots were weighed and after irrigation, their moisture variation in terms of percent was measured during stress from 2 to 10 days. The highest plant height was obtained from control. Leaf area decreased significantly despite the application of different powder, especially after 4 days of drought conditions. The highest root fresh and dry weight, raw ash were observed under control with the application of 7.5 g orange peel powder. Shoot dry weight decreased as the number of days exposed to drought increased, and the application of 15 g orange peel and cauliflower powder gave the highest results compared to control conditions. The highest dry matter was obtained from the application of 7.5 g and 15 cauliflower powder in the absence of drought. It has been revealed that as the duration of exposure to drought increases, the value decreases and plant powders are effective in increasing this value. Chlorophyll a, chlorophyll b and total chlorophyll values decreased significantly with drought, and the highest value was obtained from control conditions, followed by 15 cauliflower powder applications.

This research was carried out within the scope of spatial evaluation of the land and soil properties of Edirne-Meriç district, located in the Thrace region (Türkiye) by using GIS. Arc GIS 10.3.1 software was used in the classification of soil and land features. Digital soil maps (1/25.000 scale) were used to determine soil and land properties. Alos Palsar (12.5m) satellite images were used to determine land elevation and aspect distributions. As a result of the research, it was seen that the soil class with the largest area in terms of large soil groups in Meriç district is lime-free brown forest soils (261.2 km2). III. It was determined that class lands (153.7 km2) cover the largest area. In general, it was observed that the soil depth was greater than 150 cm (261.9 km2). It was determined that 23.3 km2 of the Meriç district lands were exposed to severe water erosion. It was determined that the study area consists of lands with a steep slope of 12-20% (126.7 km2). It has been observed that the height distribution of Meriç district lands varies between 4.7-120.5 m. It was defined that the majority of the lands were in the southwestern direction group. It is thought that the soil and land information database created as a result of the research will make significant contributions to researchers and the public, institutions and organizations.

2023
Zeyneb Yıldırım | Emine Merve Ekici
Telomeres are natural nucleoprotein structures that cover the ends of chromosomes. The phenomenon of telomere shortening, which plays a crucial role in maintaining the stability of the genome, occurs gradually over time when cells undergo division due to the end replication issue. Multiple studies have demonstrated a correlation between telomere shortening and a range of illnesses, including diabetes, dyslipidemia, cardiovascular disease, cancer, and mortality. Diet and lifestyle can affect telomere length. There exists a beneficial association between telomere length and the Mediterranean diet, particularly with regards to the consumption of dietary fiber derived from whole grains and vegetables. Micronutrients such as vitamins and trace elements also play a role in cell metabolism. Some micronutrients, such as vitamin D, folate, and vitamin B12, are associated with telomere biology and cellular aging. Vitamin B12 is essential for DNA synthesis and epigenetic methylation processes. The present systematic review examines the results from clinical trials conducted in humans evaluating the role of vitamin B12 on telomere length. Cellular senescence is a state characterized by inflammation, altered cellular metabolism, genomic instability, and telomere dysfunction, which can be induced by changes in methylation patterns and oxidative stress. Vitamin B12 maintains antioxidative defense. Through these pathways, sufficient amounts of vitamin B12 may potentially play a role in the restoration of DNA damage. Most of the evidence is based on very few randomized clinical trials. Therefore, more extensive prospective cohort studies and better-designed randomized clinical trials are required to validate the correlations outlined in this review.

Varroa destructor mite poses a serious problem for the future of bee populations around the world. Today, there are many commercial drugs with the same and different active ingredients on the market to chemically control over of Varroa destructor. More frequent chemical applications for against Varroa destructor increases stress resilience, colony losses, loss of yield and residue problems in bee products. The scope of this project is aimed to determine the appropriate control method of Varroa by investigating the efficiency values of the evaporation and dropping methods of Oxalic acid. Experimental area were chosen three different apiaries. 28 colonies were determined in each apiary and equalization studies (area with brood, number of bees with bees, age of queen bees, honey, pollen, etc.) were carried out in these colonies. The determined colonies were randomly divided into 4 groups as 7 colonies. The first group is the control group, the second group is applying 2 g of oxalic acid by vaporizing, the third group is 4% oxalic acid 5 ml of sugar syrup (1:1) is dropped between the frames, and in the fourth group, the fight against a drug that is determined by the beekeeper in the market without interfering with the beekeeper. In order to evaluate the data, samples were taken for four periods, before and after spraying in spring and autumn. While the varroa measurements in the group of syrup, vapor and spraying were found to be statistically less than the control group, the syrup, vapor and spraying groups were statistically similar in terms of varroa measurements. Oxalic acid syrup application showed higher efficiency in spring and autumn than vapor application. There is no statistically difference between both two-application method reveals that it can be used as an effective and safe alternative to chemical control against varroa.

Sugar beet is one of the most economically important agricultural crops cultivated in many provinces of Turkey. Especially in recent years, there has been an increase in bacterial tuber rot due to factors related to climate change. In preliminary trials, soft rot disease by Pectobacterium caratovorum subsp. caratovorum (Pcc) and Pectobacterium betavasculorum (Pb) were detected predominantly in sugar beets in Central Anatolia. Today, some cultural measures and copper compounds are used against soft rot agents in sugar beet, but successful results cannot be obtained in preventing the disease. In this study, a total of 270 soil samples were taken from the rhizosphere of 10 different fields in 3 different periods in 3 different ecologically diverse districts (Çumra, Altınekin and Seydişehir) of Konya, one of the provinces with the highest amount of sugar beet production in Turkey. As a result of the isolations, a total of 3064 bacterial isolates were purified and 262 of them showed antibacterial activity against Pcc and Pb in vitro conditions. In addition, 15 antagonist bacteria with the highest inhibitory effect on the development of both pathogens were tested in greenhouse conditions, and according to the results obtained from here, 3 antagonists with the highest effect were tested in field conditions in the cultivation areas of 3 different districts named above. Biochemical, morphological and molecular diagnoses of antagonist bacteria with high efficacy were made. According to the results obtained, it has been concluded that rhizospheric bacteria with antagonistic effect have a success rate of 33-90% against Pcc and Pb pathogens, and that the biological products to be prepared in future studies can be used in ecological, climate friendly and within sustainable agricultural practices in sugar beet production areas.

Bu çalışmada, Bingöl ilindeki tüketicilerin helal gıda ve içecekler konusundaki bilgi düzeyenlerinin ve farkındalıklarının tespit edilmesi amacıyla tesadüfi örnekleme yöntemi kullanılarak 374 kişiyle yüz yüze anket araştırması yapılmıştır. Verilerin analizinde tanımlayıcı istatiksel yöntemler, Mann-Whitney U ve Kruskal Wallis testi kullanılmıştır. Araştırma sonuçlarına göre; tüketicilerin satın alırken helalliği konusunda en çok şüphe duydukları ürün grubunun et ve et ürünleri olduğu tespit edilmiştir. Ayrıca, tüketicilerin %61,2’sinin helal gıda sattığını beyan eden marketlere güvenmediği, %81,3’ünün ambalajlı ürünlerin helalliği konusunda şüphelerinin olduğu belirlenmiştir. Tüketiciler, helal gıdaları, %80,7 oranında kaliteli ve %77,0 oranında sağlık ürünler olarak düşündüğünü ifade etmişlerdir. Tüketicilerin helal ürün satın alma eğiliminde ise dini hassasiyet, aileden gelen alışkanlık ve helal gıdaların daha sağlıklı olduğu düşüncesi en önemli üç faktör olarak belirlenmiştir. Tüketicilerin bir gıda ürününü satın alınırken, sırasıyla ürünün fiyatına, güvenilirliğine, kalitesine ve helal olmasına önem verdiği saptanmıştır. Kadın tüketicilerin helal gıda konusunda daha hassas davrandığı tespit edilmiştir. Helal gıda satın alırken tüketicilerin en çok ürünün helal sertifikalı olmasına dikkat ettikleri belirlenmiştir. Bu çalışmaya göre marketlerde satılan gıda ürünlerinin helalliğine yönelik ciddi şüphelerin olduğu ve Müslüman tüketicilerin güvenini artırmak için helal sertifikalı ürünlerin satılması gerektiği belirlenmiştir. Türkiye’de gıdaların helalliğinin belirlenmesinde ve belgelendirilmesinde genel bir helal standardın uygulanması tüketicilerin helal sertifikalı gıdalara güvenini arttıracak ve oluşan şüpheleri azaltacaktır.
