Development of barley after artificial inoculation with different concentrations fumonisin

Barley is a favorable substrate for the development of fungal diseases, such as fungi of the genus Fusarium spp. They produce numerous toxic metabolites, one of which are fumonisins. Theaimofthestudywas toinvestigatetheimpactonthedevelopmentandyieldof barleyafterartificialinoculationofhealthyandmechanicallydamagedseedsforsowingwithfumonisinatconcentrationsof 1 mg/l, 3 mg/l and 9 mg/l. The trial experiment with barley variety "Veslets" was conducted in the 2023/2024 season. With the carried out investigations, we found that healthy barley seeds artificially contaminated with fumonisin at a concentration of 9 mg/l have impaired germination and overwintering. In mechanically damaged seeds with the same concentration, germination and overwintering of the seeds are compromised. Fumonisin has a negative impact on the yield of barley grain, with the most significant impact at a concentration of 9 mg/l. Barley plants sprouted from healthy seeds have significantly higher average height, average weight and yield compared to plants sprouted from mechanically damaged seeds.
