Kubilay Kurtulus Bastas | Ayşegül - Gedük
Fire blight disease caused by Erwinia amylovora can infect almost 140 plants of the Rosaceae family and poses a great threat to pome fruits growing all over the world. It needs amylovoran and Type III secretion systems (T3SS) to cause disease in host plants. AmsB, AmsD, AmsE, AmsF, AmsG, AmsJ, AmsI and AmsK proteins are involved in the binding of different galactose, glucuronic acid and pyruvyl subunits to the lipid carrier to form an amylovoran unit. T3SS proteins secreted by E. amylovora are HrpA HrpN, HrpW, AvrRpt2EA, HopC1 and DspA/E. DspA/E, the sole effector of E. amylovora, is secreted by during the formation of pilus T3SS. The chaperone protein of E. amylovora is DsB/F, which is in the IA class. EopB (outer membrane protein) has been characterized as one of the secretory proteins of E. amylovora. In addition to the harpins, the pathogenicity protein DspE and OrfB proteins are secreted via the Hrp-secretory system of E. amylovora. E. amylovora forms a Hrp pilus, which is produced by the structural protein HrpA. Genes encoding antimicrobial proteins cloned and expressed in apples and pears for impart resistance to the pathogen, attacin E are cecropins and lysozymes. The expression of PR2, PR5 and PR8 proteins is increased with E. amylovora infection in apple. Again, the HIPM protein in apples interacts with the E. amylovora HrpN protein, and the HIPM protein is found in higher amounts in flowers than leaves and shoots. In addition, four apple proteins (DIPMs) that interact with E. amylovora effector protein DspA/E have an effective role in endurance. In order to understand the interaction between the plant and the pathogen, it will be possible to understand the proteins that recognize the pathogen in the host, as well as the signal system and plant defense mechanism resulting from the infection. In this study, the roles of proteins associated with pathogenesis as a result of infection of E. amylovora in apples were tried to be revealed.

Assessing available water and land for irrigation are important for planning their use. In the watershed, stream flows from some of the rivers are not known and potential irrigable areas have not been identified. By delineating watershed boundary, irrigation suitability factors such as soil type, slope, land cover/use, and distance from the water supply were classified based on the FAO guideline for land evaluation in to S1, S2, S3 and N suitability classes independently. The irrigation potential suitability analysis of soil, slope, land cover/use and Euclidean distance indicates that 55.1 %, 95.6 %, 88.6% and 93.7% respectively are in the range of highly to marginally suitable. By weighted overlay analysis, total surface irrigation suitability potential of the study area is 54.6%, from this, the potential irrigable land obtained by multi_ criteria analysis has 45.9%. The total available flow above abstraction site is 335.7m3/s or 2.9-million-meter cube (MMC) annually.

The main material of study are data were obtained from questionnaire study. In the study, face-to-face interviews were conducted with 12 enterprises which are members of Sapling Producers Sub-Union (SPSU). During the research period, there were 33 SPSU members, but the majority of these enterprises were small-sized and engaged in the purchase and sale without production. In the research, it was tried to be interviewed with all of the large capacity, both production and sales, and 12 of 33 enterprises were interviewed. The interviewed enterprises hold a large part of the grapevine sapling market. The obtained data were evaluated and interpreted by means of percentage distribution tables, average, maximum and minimum calculations. According to the results of the research, enterprises have been producing grapevine saplings on average at the commercial level for 12 years. All of the interviewed enterprises produce bare-rooted saplings. In addition, potted (58.33%) and American grapevine (25%) saplings also are produced. Grafted sapling yield rates of enterprises have been determined as 45% in own root saplings and 72% in potted sapling. 67% of the producers reported that they have problems in sapling marketing and carrying and storing saplings is a significant problem at this stage. The producers demanded that measures to prevent the informal production from authorities.

Araştırma, Çukurova Üniversitesi Ziraat Fakültesi Araştırma ve Uygulama Çiftliğinde bulunan Rio Red altıntop ağaçları kullanılarak 2011 ve 2012 yıllarında yürütülmüştür. Çalışmada, deneme bahçesindeki mevcut sulama proğramının değerlendirilmesi ile ağaçlara farklı düzeylerde uygulanan sulama suyu miktarının, verim ile meyve kalite özellikleri (pomoloji) üzerine etkilerinin belirlenmesi amaçlanmıştır. Denemede damla sulama sistemi ile 3 farklı miktarda sulama suyu uygulanmıştır (I100); (I70); (I50). Her iki yıl dikkate alındığında sulama suyu miktarları, 332,48 mm (I100) ile 128,69 mm (I50) arasında değişmiştir. Gerçek bitki su tüketimleri ise su bütçesi yöntemine göre 935,6 mm (I100) ile 729,9 mm (I50) arasında gerçekleşmiştir. Denemenin birinci yılında, sulama konularına ilişkin verimler, ağaç başına, 306 (I70) ile 330 (I50) kg, ikinci yıl ise ağaç başına ortalama verim değerlerinin sulama konularına göre, 59,6 kg (I100) ile 108,5 kg (I50) arasında değişmiştir. Toplam su kullanma randımanları, 2011 yılında, WUEET 5,18 kg m-3ile 6,34 kg m-3, 2012 yılında ise; 0,52 kg m-3ile 1,74 kg m-3arasında elde edilmiştir. Sulama suyu kullanma randımanları, 2011 yılında, WUEI 15,85 kg m-3ile 30,69 kg m-3, 2012 yılında ise; 2,17 kg m-3ile 14,27 kg m-3değerleriarasında değişmiştir. Denemenin birinci yılında ortalama suda çözünen kuru madde miktarları, %10,22 (I100) ile %12,91 (I50) arasında; ikinci yılında ise %12,41 (I100) ile %13,47 (I50) arasında değişmiştir. Bu çalışma kapsamında sulama konularının meyve verimine etkilerinin istatistiksel olarak önemli olmamasından dolayı çifçilere su tasarrufu sağlamak amacıyla yöre için su kısıntısı önerilebilir.
