Özet
İzmir ili ve çevresinde yetiştirilen enginar, pırasa, karnabahar, lahana, marul, soğan, brokkoli ve Brüksel lahanası, gibi kışlık sebzeleri enfekte eden virüsleri tanılamak ve bulunma durumlarını saptamak amacıyla 2010 ve 2011 yıllarında surveyler yapılmıştır. Hastalıklı bitkilerde en fazla rastlanan virüs belirtilerinin bitki gelişmesinde gerileme, sararma, mozaik, beneklenme, yapraklarda ve gövdede bükülme, kıvrılma, lekeler veya çizgiler ve yaprak ve meyvede oluşum bozuklukları olduğu görülmüştür. Virüsleri tanılamak için, adı geçen sebze türlerinin belirti olan ve olmayan bireylerinden toplam 218 örnek alınmış ve bunlar biyolojik, serolojik ve moleküler yöntemlerle test edilmiştir. Elde edilen sonuçlar, testlenen örneklerde virüs enfeksiyonu bulunma düzeyinin % 38.1 olduğunu ve bu çalışmadaki örneklerde en yaygın olarak Cucumber mosaic cucumovirus (CMV) ve Radish mosaic comovirus (RaMV)’nün bulunduğunu ve bu etmeni, Lettuce mosaic potyvirus (LMV), Turnip mosaic potyvirus (TuMV), Leek yellow stripe potyvirus (LYSV) ve Artichoke latent potyvirus (ArLV) adlı etmenlerin izlediğini göstermiştir. Testlenen örneklerde en fazla virüs enfeksiyonunun karnabahar, marul ve soğanda olduğu, bunları Brüksel lahanası, lahana, enginar ve pırasanın izlediği görülmektedir. Ayrıca; karnabahar, marul ve soğan örneklerinde % 0.5 ile % 27.7 arasında değişen oranlarda birden fazla sayıda virüsün neden olduğu karışık enfeksiyonların olduğu görülmüştür. Mevcut bilgilerimize göre, sağlanan bulgular Türkiye’de ArLV’nün enginar ve CMV’nün ise lahana bitkilerindeki doğal enfeksiyonları konusunda ilk kayıt olma özelliğini taşımaktadır.
The surveys were conducted to determine the presence and prevalence of the viruses infecting cold-season vegetable crops including globe artichoke, leek, cauliflower, cabbage, lettuce, onion, broccoli and Brussels sprouts in the production areas of Izmir province and its around between the years 2010 and 2011. During the surveys, the common viral symptoms were the reduction in overall plant growth, yellowing, mosaics, mottling, leaf distortion, leaf crinkling, spots or streaks on leaves and stem, and leaf and fruit formation disorders. To identify viral agents, a total of 218 samples were randomly collected from symptomatic and asymptomatic plants and were subjected to biological, serological and molecular tests. The results showed that the overall incidence of virus infection was 38.1 % in the tested samples. Cucumber mosaic cucumovirus (CMV) was the most prevalent virus in the samples of our work, followed by Radish mosaic mosaic comovirus (RaMV), Lettuce mosaic potyvirus (LMV), Turnip mosaic potyvirus (TuMV), Leek yellow stripe potyvirus (LYSV) and Artichoke latent potyvirus (ArLV). The highest rates of virus infection among occurred in cauliflower, lettuce, onion and they were followed by Brussel sprout, cabbage, artichoke and leek. In addition, mixed infections caused by more than one viral agent were found in some specimens from plants of cauliflower, lettuce and onion at the rates ranging between 0.5 % and 27.5 %. To our knowledge, the some findings in the present study are the first report of natural infections of artichoke by ArLV and cabbage by CMV in Turkey.
