Sažetak
Six wheat genotypes (Triticum aestivum L.) resistance (R) and susceptible (S) to Fusarium head blight were studied at the Agricultural Institute Osijek during 2015/2016 vegetation season under control and artificial Fusarium infection. The percentage of diseased heads as general Fusarium resistance was calculated after assessing a random sample of 30 heads on 26 days after inoculation. The amount of gliadins (GLI), glutenins (GLU) and their components were measured in whole grains by RP-HPLC. GLI and GLU have a very important role in defining dough viscoelastic properties. Golubica as S cultivar had the highest percentage of diseased heads (55%) in contrast to Vulkan as R cultivar (8%). S cultivar Golubica had the largest increase of GLI (13.31%) and the largest decrease of GLU (20.60%) and high-molecular-weight glutenin subunits (HWW) (27.4%) in contrast to R cultivar Kraljica whose GLI increase was 5.74%, GLU decrease 16.43% and HMW decrease 11.28%. S cultivar Sana showed significantly smaller changes in GLI (9.54%), GLU (12.9%) and HMW (7.53%) compared with other S cultivars, while R cultivar Vulkan is the only one with GLI decreasing (15.74%) and GLU and HMW increasing (11.25 and 11.66%, respectively) under artificial infection. In conclusion, a higher level of Fusarium infection had a considerable negative effect on GLI/GLU balance in whole wheat grains.
