Influence of Fusarium artificial infection on agronomic traits of wheat

Abstract

Velike štete na pšenici mogu uzrokovati vrste iz roda Fusarium. Najveće štete prave one vrste koje se javljaju na klasu i izazivaju fuzarijsku palež klasa (FH3) koja, osim što umanjuje prinos, im anegaticnih učinaka i na svojstva kvalitete. Cilj istraživanja bio je utvrditi utjecaj umjetne zaraze Fusariumom na agronomska svojstva pšenice. Genotipovi u tretmanu Fusariumom u odnosu na kontrolu u prosjeku imali su niži urod zrna za 12,4 %, pri čemu su najmanje gubitke u tretmanu Fusariumom u odnosu na kontrolu imali genotipovi Soissons, Aida i Osk. 870/08. U tretmanu Fusariumom u odnosu na kontrolu genotipovi su imali hektolitarsku masu u prosjeku nižu za 2,4%. Za masu 1000 zrna nisu dobiveni konstantni podaci među tim dvama tretmanima te je u tretmanu Fusariumom bila veća nego u kontrolnome tretmanu u prosjeku za 1%.Great damage to wheat can be caused by species from the genus Fusarium. The greatest damage occur in the ear and cause Fusarium head blight (FHB), which reduces yield and has negative effects on quality traits. The aim of this study was to determine the effect of artificial infection of Fusarium on agronomic traits. Genotypes in the treatment of Fusarium in relation to the control treatment in average had lower grain yield of 12.4%. Minimum loss in the treatment of Fusarium in relation to the control had genotypes Soissons, Aida and Osk.870/08. In the treatment of Fusarium in relation to the control, genotypes had a test weight lower for 2.4% in average. A thousand kernel weight values did not obtain stability between these two treatments, and values in the Fusarium treatment were higher than in the control treatment of 1% in average
