Verticillium Wilt Disease is one of the most important diseases affecting the rate of cotton yield. There is no economic chemical control for Verticillium wilt, but it is recommended to use resistant varieties to control this disease. This experiment was carried out in a randomized plot design with four replications in the growth chamber to determine the response of some cotton cultivars against a defoliating and non-defoliating pathotypes of Verticilllium dahliae Kleb. In the study, a total of twenty cotton cultivars i.e. the resistant control GIZA 75, the tolerant control CARMEN and the susceptible control ACALA SJ2, defoliating (PYDV6 isolate) and non-defoliating (Vd 11 isolate) pathotypes were used, and cotton varieties were tested using conidial suspension technique. Analysis of variance showed significantly (P

2017
Hakan Şevik | Mehmet Çetin | Kerim Güney | Nur Belkayalı
Günümüzde insan ömrünün en az %80’i kapalı mekanlarda geçmekte ve bu kapalı mekanlardaki iç ortam hava kalitesi insanların sağlıklarını ve performanslarını doğrudan etkilemektedir. Özellikle CO2 miktarı belirli seviyelerin üzerine çıktığında baş ağrısı, baş dönmesi, yorgunluk, konsantrasyon bozuklukları, boğaz ve burun tahrişi, burun akıntısı, öksürük ve göz akıntıları gibi pek çok rahatsızlığa sebep olmaktadır. İç ortamdaki CO2 miktarını etkileyen en önemli faktör canlı metabolik faaliyetleridir. Solunumla artan CO2 miktarı fotosentezle azalmaktadır. Dolayısıyla iç mekanlarda bitkiler CO2 miktarını azaltmak amacıyla kullanılabilir. Ancak bitkilerin iç ortamdaki hava kalitesine etkisi konusunda yeterli bilgi bulunmadığından, bitkiler iç ortamdaki CO2 miktarını azaltmak konusunda etkin ve bilinçli bir şekilde kullanılamamaktadır. Bu çalışmada iç mekan süs bitkisi olarak en sık kullanılan bitkilerden birisi olan difenbahyanın (Dieffenbachia amoena Gentil) iç ortamdaki CO2 miktarına etkisinin sıcaklığa bağlı olarak değişiminin belirlenmesi amaçlanmıştır. Çalışma sonucunda difenbahyanın karanlık ortamda yaptığı solunumun sıcaklığa bağlı olarak önemsiz düzeyde olduğu belirlenmiştir. Ancak ışık bulunan ortamda en yüksek etkiyi 23-24℃ sıcaklıklarda gösterdiği, 30°C sıcaklıktaki fotosentez hızının, 20°C dekinden düşük ancak 15°C dekinden daha yüksek olduğu belirlenmiştir.

2017
Ibarahim Mayanja | Tolga Tipi
This study focuses on empowering women both in peri-urban and rural areas through mushroom production. It was conducted in Kampala Metropolitan area-Uganda, during October 2016. It focused on estimating profits, conducting benefit-cost analysis/ratio (BCR) and return on investment (ROI), finding reasons as to why women involved in the mushroom production and identifying the constraints of mushroom farming from the perspective of women as well as the possible solutions to the constraints. 29 women were interviewed face to face through the use of the questionnaires. The study revealed an average net profit of 3,464.28 US dollars, BCR of 3.84 and ROI of 2.84 per farm in a period of three months. Our study revealed that mushroom production is a profitable enterprise for women. The major reason for women to involve in mushroom was to earn income. However, a range of other reasons was given such as fast maturity of mushrooms, availability of market, healthy benefits of mushrooms, etc. were the most important reasons. The problems faced by women farmers were ranked from the most pressing problem to the least pressing problem in this order; Low market prices per kilogram of mushroom, scarcity of cotton during some seasons, poor quality mushroom spawn supplied to farmers by breeders, inadequate extension, and advisory services were the most observed problems among others. The suggested solutions were organizing farmers into groups or cooperatives in order to negotiate for better markets locally and abroad together with the help of government, researchers to carry out more research on the suitability of other substrates like bagasse other than relying on only cotton, ensuring that mushroom spawn breeders conform to the set standards of quality spawn production and re-equipping local extension workers with knowledge regarding mushroom production among others.
Mostrar más [+] Menos [-]Seafood Consumption Attributes and Buying Behaviours According to the Generations: A Study on Millennial Generation in Turkish Market
2017
Osman İnanç Güney | Levent Sangün
This paper focus on the seafood consumption attitudes and behaviours of the millennials (Generation Y) and non-millennials (Generation X, Baby Boomers and Silent Generation) comparatively. The data was collected from a face to face survey which was applied to randomly select 407 individuals in the city of Adana, Turkey in November 2016. As a result of factor analysis applied in the study, it was found that Millennials was significantly and inversely correlated with consumption of wild fish and freshwater fish. Non-millennial generation was inversely correlated with consumption of marine fish, freshwater fish and mussels and the correlation is insignificant. According to the results of the chi square test, it was determined that Millennials mostly preferred to consume fresh (unprocessed) fish. Mann-Whitney test results show that they value health and nutrition factors for consumption and there is a significant difference between these two factors. Besides, factors mainly effecting their purchase behaviour of seafood are directed to freshness, seasonality, place of purchase and wild-aquaculture product classification and there are significant differences between these factors. The fact that the Millennial’s average response to consumption and purchasing is higher indicates that they are more cautious.
Mostrar más [+] Menos [-]Determination of Viable Salmonella Typhimurium Cells in Heat Treated Milk By PMA/Real-Time PCR Method
2017
Zülal Kesmen | Hakiye Aslan
Applying different technological processes during the production of food has a lethal effect on the bacteria but DNA of these bacterial strains may cause false positive results when detected by real time PCR technique because they preserve their existence for a certain period of time. To overcome this shortcoming of the real time PCR technique, a new method has been developed in recent years, based on the removal of dead cell DNA from the medium by treatment with Propodium Monoazide (PMA) before DNA extraction. In this study, real-time PCR method was combined with PMA application for the detection of live cells of Salmonella Typhimurium in heat treated milk samples. For this purpose, milk samples inoculated with S. Tyhimurium were heat treated at different temperatures (60, 65, 70 and 75°C) and times (15, 60, 300, 900 sec) and number of live bacteria was determined comparatively by direct real-time PCR, PMA/real-time PCR and conventional cultural method. As a result, unlike the direct real time PCR technique, PMA/real-time PCR method prevents to a certain extent of false positive results from dead cells at all tested temperatures and times but higher results were obtained from PMA/real-time PCR method when compared to conventional cultural results. Therefore, further studies should be carried out to optimize the conditions of the PMA application in order to eliminate the high positive results detected by the PMA / real-time PCR method

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.
Mostrar más [+] Menos [-]Late Blight of Potato (Phytophthora infestans) I: Fungicides Application and Associated Challenges
2017
Abdul Majeed | Zahir Muhammad | Zabeeh Ullah | Rafi Ullah | Habib Ahmad
Potato (Solanum tuberosum L.) has been remained an important agricultural crop in resolving global food issues through decades. The crop has experienced enormous growth in terms of production throughout the world in recent decades because of improvement in agricultural mechanization, fertilizers application and irrigation practices. Nevertheless, a significant proportion of this valuable crop is still vulnerable to losses due to prevalence of different viral, bacterial, fungal and nematodes infestations. Late blight, caused by Phytophthora infestans (Mont.) de Bary, is one of the most threatening pathogenic diseases which not only results in direct crop losses but also cause farmers to embrace huge monetary expenses for disease control and preventive measures. The disease is well known for notorious ‘Irish Famine’ which resulted in drop of Irish population by more than 20% as result of hunger and potato starvation. Globally, annual losses of crop and money spend on fungicides for late blight control exceeds one trillion US dollars. This paper reviews the significance of late blight of potato and controlling strategies adopted for minimizing yield losses incurred by this disease by the use of synthetic fungicides. Advantages and disadvantages of fungicides application are discussed.
