Abstract

Fungal pathogens can significantly reduce the potential yield and seed quality of cereal crops, the major risk is contamination with toxic fungal secondary metabolites known as mycotoxins, which have negative consequences in human and animal health. The influence of different concentrations of the oregano, basil and thyme essential oils on the development of the mycelium of Fusarium, Aspergillus, Penicilium species was analyzed and action of inhibiting the capacity of molds’ occurrence and development at stored wheat and maize. The chemical composition of the all essential oils was determined by gas chromatography/mass spectrometry analysis. Oregano and basil essential oils inhibit completely development of Fusarium spp., Penicillium sp. and Aspergillus sp. pathogens at 2000-5000 ppm concentration exerted a fungitoxic effect. However, thyme oil in 10-100 µl/ml concentration was the strongest in fungicidal activity of the tested Fusarium, Penicilium, Aspergillus, species. In conclusion, all essential oils used in this study could be suitable for applications in the food industry to control molds and improve the safety of stored grain.

精油抑制储藏谷物主要腐败真菌发展的抑菌活性

真菌病原体可以显著降低谷类作物的潜在产量和种子质量，主要风险是被称为真菌毒素的有毒真菌次级代谢物污染，这对人类和动物健康产生负面影响。分析了不同浓度牛至、罗勒和百里香精油对小麦和玉米储藏中镰刀菌、曲霉、青霉菌丝体发育的影响及抑制霉菌发生和发育的作用。采用气相色谱/质谱联用分析方法测定各挥发油的化学成分。牛至和罗勒精油完全抑制镰刀菌、青霉菌和曲霉菌病原菌的发育，2000 ~ 5000ppm浓度对病原菌具有抑菌作用。而百里香油在10 ~ 100µl/ml浓度下对镰刀菌、青霉、曲霉的抑菌活性最强。综上所述，本研究中使用的所有精油都可以在食品工业中应用，以控制霉菌和提高储粮的安全性。

期刊介绍： The Journal ROMANIAN AGRICULTURAL RESEARCH is an “open access” one, which publishes original articles, short communications, presenting new scientific results – theoretical, experimental and technical – on plant breeding and genetics, physiology, biotechnology, mineral nutrition and plant protection, in field crops. Reviews on up-to date subjects and recent research, preferably from Eastern Europe, may also be published.
