Abstract

The aim of this study was to determine fungal factors causing ear rot and the detection of toxin contamination levels in main and second crops corn during harvest periods in Adana between 2015-2016. Totally 134 corn fields were sampled during the survey studies and Fusarium, Aspergillus and Penicillium were isolated from the corn grains. Aspergillus flavus, A. terreus A. niger, Fusarium verticillioides, F. graminearum, F. culmorum, Penicillium verrucosum and P. carneum were identified according to the morphological characteristics of these isolated fungi. Competitive Direct Enzyme-Linked Immunosorbent Assay (CD-ELISA) analysis was performed for mycotoxin (aflatoxin, T-2, zearalenone, ochratoxin) detection of the corn samples. As a result of the mycotoxin analysis, 0.3-72.6 μg/kg aflatoxin was found in 48 corn samples, 1.5–75.0 μg/kg T-2 was seen in 48 corn samples, 3.4–551.9 μg/kg Zearalenone was observed in 134 corn samples, and finally 1.0–6.5 μg/kg ochratoxin was determined in 15 corn samples.

Özet

Bu çalışma ile Adana ili 1. ve 2. ürün mısır alanlarında 2015-2016 yılı hasat döneminde, koçan çürüklüğüne neden olan fungal etmenler ve bu fungal etmenler ile bulaşık mısır örneklerinde toksin bulaşma seviyelerinin tespit edilmesi amaçlanmıştır. Tarama çalışmalarında toplam 134 mısır tarlasından örnekleme yapılmış ve elde edilen mısır tanelerinden Aspergillus, Fusarium ve Penicillium cinsi funguslar izole edilmiştir. İzole edilen bu fungusların morfolojik özelliklerine göre yapılan tanımlama sonucunda Aspergillus flavus, A. terreus, A. niger, Fusarium verticillioides, F. graminearum, F. culmorum, Penicillium verrucosum ve P. carneum türleri belirlenmiştir. Mısır örneklerinde mikotoksin (aflatoksin, T-2, zearalenon, okratoksin) araması için, CD-ELISA (Competitive Direct Enzyme-Linked Immunosorbent Assay) analizi uygulanmıştır. Mikotoksin analizi sonucunda, 48 mısır örneğinde 0.3–72.6 μg/kg aflatoksin, 83 mısır örneğinde 1.5–75.0 μg/kg T-2, 134 mısır örneğinde 3.4–551.9 μg/kg zearalenon, 15 mısır örneğinde ise 1.0–6.5 μg/kg seviyelerinde okratoksin içerikleri belirlenmiştir.
