Öğe Drying and drying systems in vegetables(EJONS, 2020) Malakaşlı, Salih; Karipçin, M. ZekiVegetable or fruit to be dried to remove the water is called drying process. Since the moisture content of vegetables or fruits will be very low, the shelf life is increased parallel to the reduced moisture content. Because the microorganism activities in food is minimized. As a result, the shape and color of the food change. With the removal of the water forming the weight, the weight of the food in unit weight is reduced. Again, the amount of dry matter of the same food increases with the removal of water. The main purpose of drying is to ensure that the food is delivered to human nutrition in a healthy way outside the season. Therefore, drying methods are important for health. In the drying stage, the risk of transmission of the disease pathogen and the risk of virus transport by the effect of different insects and rodents indicate that this sector should not be randomized. An infected plant with an alpha toxin or a dried apple dried under high radiation, or any food infected by mice and other animals, will have a very negative impact on our health. Drying for the helping of the family economy or for the taste of the palate has become a big sector today. It is said that vegetables and fruits grown outside of the season are not hormone. A food to be consumed outside the season is more desirable than dried. Figs and grapes in fruits and tomato and pepper in vegetables are the essential foods can be dried. But how are our drying methods and storage conditions correct in terms of health? We can demonstrate the feasibility of this sector by using old technology, using new technology and taking into account new demands. Only dried tomato vegetables have an export potential of approximately $ 70 million. The sector which will be formed by drying various vegetables in Siirt province which has natural drying sources (Sun, wind) will contribute to the economy of the province.Öğe Effect of arbuscular mycorrhizal fungi (AMF) on growth and nutrient uptake of lettuce (Lactuca sativa) under water stress(Centenary University, 2016) Karipçin, M. Zeki; Şatir, N. YoncaThis study was carried out to determination effect of mycorrhiza to yield and yield component of lettuce (Lactuca sativa) under water stress condition. Water levels of 100 % and 50 % and Glomus mycorrhiza were applied on lettuce at the non-heat greenhouse of GAP Agricultural Research Institute. Canopy diameter, head weight, head diameter, head length, marketable leaves number, marketable leaves weight, unmarketable leaves weight, total leaves numbers, root collar diameter, root width and root length were measurement and also some micro and macro nutrient were investigated. Spore and infection rate at the root zone were determined. As a result the full irrigation effected as positively to the yield and yield component of lettuce, with more irrigation caused N increasing and the highest Fe content was determined at the applied mycorrhiza and at the full irrigation parcel. The highest spoore numbers (86.67) and rate (56.67 %) of root zone were determined at the 50 % irrigation level. © 2016, Centenary University.

Zeki; Ahmed Ahmed, Mohammed; Yaşar, FikretThis project was developed to investigate the contribution of salicylic acid to development of pepper seedlings grown in low temperature (0 0C) conditions. The research was carried out in the controlled plant growing cabinet in the re-search- investigation area of the Department of Horticulture, Faculty of Agriculture, Siirt Uni-versity. As a vegetable material, Urartu F1 pep-per type (capia) which is used in greenhouse cultivation has been used. As a dose of different salicylic acid; 0.01 and 0.05 mmol doses were applied. The dose of 0 mmol salicylic acid was used as control group. Application frequency; It was applied 1 time, 2 times and 3 times.3 different cold application times were also investigated; 24 hours, 48 hours and 72 hours. The experiment was designed in randomized plots and 3 replications. In the pepper seedlings the effect of the seedlings on the WRKY genes were investigated. Considering the administra-tion of both salicylic acids, it was found that 0.05 mmol dose had a clearer and more under-standing response to the expression of WRKY gene.Öğe Geothermal resources in Siirt and their opportunities for greenhouse(EJONS, 2019) Malakaşlı, Salih; Karipçin, M. ZekiIt is known that hot water resources of Siirt province which is filled with various natural resources, have high potential. In order to determine the usage possibilities of Siirt thermal resources (hot water) and greenhouse cultivation, geothermal potential of Siirt province and the use of this resource especially in greenhouse cultivation have been determined by using the data of other related institutions (DSİ, Siirt Il Özel İdaresi), especially the Maden Tetkik ve Arama Genel Müdürlüğü (MTA). The geothermal resources of Siirt province; total number, distance to center, flow rate, water temperatures, depth properties were investigated. Siirt province geothermal resources are known in total 2, one of them is Lif and the other is Bilores which is the closet to center. Biloris water temperature of the geothermal source has 34.5 °C degree and the temperature of the Lif geothermal source is 33.1 °C. In terms of flow rate, which is as important as water temperature in greenhouse cultivation, the highest flow rate (90 L/second) belongs to Biloris source, Lif source was found to be the lowest flow rate (10 L/second). In addition, it was found that the well of the MTA, which is 696 m in depth, has a water temperature of 45 ° C and 7 L/second flow rate. It has been determined that these geothermal resources can be used in greenhouse cultivation in terms of number, area and water temperature and flow potential.Öğe Kök ortamlarının karpuz kök yapılarına etkileri(EJONS, 2019) Kılınç, Hafif; Karipçin, M. ZekiKuraklığa tolerantlıkları TÜBİTAK (107T613) projesi ile belirlenmiş bazı karpuz genotiplerinin kök yapılarına farklı kök ortamlarının etkilerini incelemek amacıyla yürüttüğümüz bu çalışmada, Kar 24, Kar 98, Kar 39 (Crimson Sweet) karpuz genotipleri kullanılmıştır. Kök ortamı olarak ise kum, toprak ve torf materyalleri kullanılmıştır. Tüm bitkiler aynı tarihte ve 3 tekerrürlü olarak plastik tüplerde yetiştirilmiştir. Kök yapılarının yanı sıra; çıkış zamanları, bitki yaş ağırlığı, bitki kuru ağırlığı, kök yaş ağırlığı, kök kuru ağırlığı, bitki kuru madde oranı, kök kuru madde oranı ölçümleri gerçekleştirilmiştir. Ayrıca bitki yeşil aksam boyu ve bitki yeşil aksam eni (Taç eni) ile Kök eni ve kök boyu Image J programı aracılığıyla taranarak belirlenmiştir. Toprak ortamındaki bitkilerde tam randıman alınamamıştır. Çalışmada kullanılan kök ortamlarından olan kum ortamının en erken çıkışı sağladığı, kum ortamındaki Kar 98 bitkilerinin bitki kuru madde oranı bakımından diğer ortam ve bitkilerden daha üstün olduğu, kök kuru madde oranı açısından ise torf ortamındaki Kar 24 (kuraklığa tolerant) genotbine ait verilerin daha yüksek değerlerde bulunduğu, Kar 98 (kuraklığa hassas) genotibinin torf ortamındaki bitkilerden elde edilen bitki boyu değerlerinin diğer genotiplere ait değerlerden daha üstün olduğu, taç eni değerleri arasında ise torf ortamındaki Kar 39 (Crimson Sweet-tolerant/intolerant) bitkilerine ait taç eni değerlerinin daha yüksek değerler olduğu saptanmıştır. Köklerin derinliğini gösteren kök boyu değerleri açısından ise Torf ortamındaki Kar 24 genotibinin en yüksek kök boyu değerlerine sahip olduğu tespit edilmiştir. Kullanılan her bir genotip farklı genetik yapılara ve kuraklığa tolerantlıklara sahip olduğundan dolayı elde edilen veriler daha önemli olmaktadır. Kum ortamının besin içeriğinin fakir olmasından dolayı besin takviyesine ihtiyaç duyduğu, besin takviyesi ile kum ortamındaki bitkilerin erken çıkış sağlayarak en iyi kök yapılarını oluşturmaya en uygun ortam olduğu saptanmıştır.Öğe Morphological changes of salicylic acid application on pepper (capsicum annuum l.) seedling under cold condition(International Journal of Secondary Metabolite, 2019) Ahmed Ahmed, Mohammed; Karipçin, M. Zeki; Yaşar, FikretThis project was developed to investigate the contribution of salicylic acid (SA) to the development of pepper seedlings grown in low temperature (0 0C) conditions. The research was carried out in the controlled plant growing cabinet in the research- investigation area of the Department of Horticulture, Faculty of Agriculture, Siirt University. As a vegetable material, Urartu F1 pepper type (capia) which is used in greenhouse cultivation has been used. As a dose of different salicylic acid; 0.01 and 0.05 mmol doses were applied. The dose of 0 mmol salicylic acid was used as a control group. Application frequency; It was applied 1 time, 2 times and 3 times.3 different cold application times were also investigated; 24 hours, 48 hours and 72 hours. The experiment was designed in randomized plots and 3 replications. In the pepper seedlings Rate of Lost Seedling Weight (ROLSW) and Rate of Lost Seedling Length (ROLSL) were investigated. At the end of the research; Both SA applications increased the ROLSW rate according to the control. The application of 0.01 ppm was the SA application with the highest ROLSW rate. The application of 0.01 ppm SA also increased the ROLSL rate compared to the control. The highest ROLSW and ROLSL rates were obtained from 24-hour cold application. There was no statistically significant difference between the frequencies of application.Öğe Physiological and gene-expression variation in watermelon (citrullus lanatus l.) cultivars exposed to drought stress(Polish Botanical Society., 2020) Erez, Emre; İnal, Behcet; Karipçin, M. Zeki; Altıntaş, SerdarDrought conditions may have direct or indirect effects on plant physiology, biochemistry, and molecular characteristics. The purpose of this study was to investigate the effects of drought stress on the physiological, biochemical, and molecular responses of three different watermelon cultivars with varying levels of drought tolerance (24: drought resistant, CS: moderately tolerant, and 98: drought sensitive). The cultivars exhibited different responses to cope with water stress according to their tolerance level. Drought induced significant reductions in chlorophyll a, total chlorophyll and carotenoid content and glutation reductase and ascorbate peroxidase activity in the sensitive cultivar unlike in the moderately tolerant and drought resistant cultivars. Additionally, the expression levels of NAC1, NAC2, ORE1, WRKY24, SAG12, SAG13, KCS2, CER1, DREB2A, LTP3, SWEET15, and PYL9 genes were measured using qRT-PCR. The expression ratios of the genes significantly varied depending on the gene location and on the tolerance of the cultivars. Results showed that the physiology and biochemical and molecular pathways of tolerant cultivars change to adapt to drought conditions. Therefore, the drought-resistant cultivar copes with drought stress by increasing proline content and antioxidant enzyme activities, as well as by increasing the expression of specific genes.Öğe Siirt yöresinde sebze olarak tüketilen bazı yabancı otlar(EJONS, 2019) Tuncay, Emrah; Karipçin, M. ZekiSiirt ili yenilebilir otlar bakımından oldukça zengindir. Kış ve İlkbahar mevsiminde bol yağış alan Siirt ilinde yenilebilir otlardan oluşan yemek kültürü zengindir. Yılanyastığından (Arum maculatum) kenger otuna (Gundelia tournefortii), peynir otundan ısırgan otuna kadar çeşitli türlerde yenilebilir otlar mevsiminde toplanarak gerek çiğ gerekse pişirilerek veya salamura yapılarak tüketilmektedir. Tamamen “doğal” ortamında toplanan, çeşitli işleme tekniklerinden ve insan müdahalelerinden uzak şekilde yetişen ancak mevsiminde bulabildiğimiz ve tükettiğimiz, en önemlisi de tarımı yapılmayan ve sebze niyetine kullanılan otlardır çalışmamızın konusu. Bu otların birçoğu başka yörelerde bulunabilmektedir. Doğal sebze olarak nitelenen bu otlar, farklı metotlarla günlük gıda gereksinimlerimizi karşılayan yiyecekler arasında bulunmaktadır. Bazıları için yılda en az bir kere yenmeli dusturundan yola çıkılarak gerçekleştirdiğimiz bu çalışmamızda Siirt bölgesinde sebze olarak tüketilen bazı otlar bölge insanı ile görüşülerek tespit edilmiştir. Tespit edilen yenilebilir otlar arasında; Korpit (Rışvat veya Dêjnik de denir), Kenger, Ahbandır, Strizek (Altındiken), Kardi (Yılanyastığı), Isırgan otu, Sırdim (Yabani sarımsak), Ebegümeci (Tolık), Kuzukulağı, Işgın otu bunların başlıcaları arasındadır. Özellikle etken maddelerinin sağlığımız açısından önemine dair yapılan araştırmaların sonuçlarına göre bu otlara talep her geçen gün artmaktadır. Gerek şekilleri ve gerekse isimlerinden dolayı bu otlar ekzotik (exotic) sebzeler grubuna da girebilecek türlerdir. Kültüre alınmamaları ve kayıtlı pazarlama piyasalarında ticarete konu olmamalarından dolayı da minör sebzeler grubuna girebilmektedirler. Her birinin yüksek tecrübelerle aktarılmış hikâyeleri vardır. Her bir yenilebilir otun sağlığımız açısından çok değerli ve telafi edilemeyecek değerde önemi bulunmaktadır. Erken ilkbaharda başlayan yenilebilir otların toplanmasına mevsim koşullarına bağlı olarak Mayıs ayının sonuna kadar devam edilmektedir. Bu otlardan bazıları toplandığı gibi çiğ olarak veya pişirilerek tüketilmektedir. Bazı otlar ise salamura halinde işlenerek tüketilmektedir.Öğe Water deficit tolerance of some pepper inbred lines(TURJAF, 2019) Keleş, Davut; Pınar, Hasan; Ata, Atila; Bircan, Mustafa; Karipçin, M. Zeki; Rastgeldi, Ufuk; Büyükalaca, SaadetWater deficit is one of the main limiting factors affecting plant growth. Selection in water-limited environments can result in populations or species with improved response to drought. Water deficit decreases yield and quality, therefore, it is important to identify genotypes that are tolerant to deficit irrigation conditions. In this study, the water-deficit tolerance of 59 pepper-inbred lines was determined. Experiments were conducted in a growth chamber and under field conditions (Şanlıurfa) with a control (100% full-irrigation) and water-deficit treatment (50% irrigation). Fruit weight, fruit length and number of fruits were recorded. Pepper lines 1900, 896 A-W, 74, 760, 1560-W, 912 A-W, 405-A, 953-W, 226, 1105-W and 441 were identified as the most tolerant to water deficit conditions. Present findings revealed that these pepper lines could be used to develop cultivars that have satisfactory yield under water deficit conditions.
