THE INFLUENCE OF ENVIRONMENTAL AND STORAGE FACTORS ON THE QUALITY OF WINTER WHEAT GRAINS

Abstract

To assess the influence of environmental factors on the quality indicators of winter wheat grains, in 2022, after harvesting, grain samples were collected from areas representing different regions of Lithuania (8 samples in total). Samples weighing 3 kg were taken from local farmers' warehouses. Mycotoxins deoxynivalenol (DON), trichothecenes (TR), zearalenone (ZEN), aflatoxins (AFL) ochratoxins (OCH), studies on the determination of the number of drops were carried out at the State Crop Production Service under the Ministry of Agriculture, other qualitative indicators were evaluated with the analyzer "Infratec" and using visual identification and LST EN ISO 3093.

In summary, it can be said that in different regions of Lithuania, the differences in the quality of wheat grains can be seen very clearly, this could be determined by many biotic and abiotic factors, such us agrotechnical conditions, soil properties, meteorological conditions, and distribution and diversity of microorganisms.
