Sažetak
Wheat ears can be infected with Fusarium graminearum from flowering till the end of vegetation. Reduction in yield quantity and quality depends on the infection time, genotype susceptibility, Fusarium species and isolate pathogenicity. This experiment was performed on 24 wheat genotypes planted on trial fields of the Agricultural Institute Osijek. Artifical infection of wheat ears was done in three different time frames: at full flowering (when 50% of flowers are flowering), end of flowering and 8 days after the end of flowering. After the ears were harvested we determined TKW, percentage of infected grains, their germination and DON contamination. For all genotypes, the highest reduction of TKW (14.86 - 43.49%) was observed after infection at full flowering. When infection was done at the end of flowering reduction in TKW was between 6.5 and 28.92%, and after third infection it was between 0.93 and 19.41%. Percentage of infected grains was the highest and their germination the lowest with the early infected grains. We also determined statistically important differences in susceptibility of genotypes on Fusarium ear blight regardless of time of infection. With the most genotypes we did not determine statistically significant differences between DON content and infection time.
