description

Abstract The correlation between the occurrence of four enniatins (ENA, ENA1, ENB, and ENB1) and beauvericin (BEA) and the weather parameters during anthesis and preharvest period was studied in 97 wheat samples collected in 2014 and 2015 across three counties from central and south Romania (Brasov, Dâmboviţa, and Teleorman). The highest mean values of ENA (16.1 μg kg −1 ) and ENB (147.1 μg kg −1 ) were measured in the samples from Brasov county in the harvest year 2015, whereas for ENA1 and ENB1 the highest means (55.2 μg kg −1 , and 108.0 μg kg −1 , respectively) were noted in samples from Teleorman county in 2014. Statistically significant differences ( P r s  = 0.8745 and r s  = 0.9326; ENB1: r s  = 0.7814 and r s  = 0.8909, for temperature and precipitation, respectively). Principal component analysis revealed that the influence of weather parameters on emerging mycotoxin concentrations in wheat samples varied by region. This study showed that the presence and levels of emerging mycotoxins are related to weather parameters from the respective Romanian region.
