In recent years, public attention has increasingly focused on the production and
consumption of high quality safe food. Changes in the dietary trend have
influenced the formation of specific market requirements that have led to the
fact that in the diet are increasingly used alternative cereals of high nutritional
value, in addition to conventional. The ancient wheat species spelt [Triticum
aestivum subsp. spelta (L.) Thell.] has a growing interest due to its various
health benefits. Due to its biological and agronomic characteristics, spelt takes
an important place among alternative cereals. The aim of this study was to
investigate the natural occurrence of pathogenic and toxigenic fungi on seven
breeding lines of spelt grains in 2021 grown in Zemun Polje, Serbia. Based on
morphological properties (colony and spore appearance) it was determined that
breeding line 6337 was the least infected (2,2%) and that the peeled grains had
a lower degree of infection compared to grain...s with glumes. Glumes have been
shown to be a physical protection against pathogens. Mycological analyses
confirmed the presence Aspergillus spp., Alternaria spp., Fusarium spp. which
were the most prevalent. Considering the average values, the most frequent
were Aspergillus section Nigri (1,64%). Significance of Aspergillus section
Nigri is reflected not only in the deterioration of spelt grain yield, quality and
large economic losses but also in the fact that many species of this genus
produce toxic metabolites (mycotoxins), which are harmful to human and
animal health. Climate change and high adaptability and resistance of toxigenic
Aspergillus species are cited as the reason for this phenomenon.
