The aim of this study was to determine the profile of fungal metabolites and antioxidant substances from plants on a representative population of wheat cultivars grown in Poland. Tests were conducted on grain of 23 wheat cultivars in three experimental variants: natural infection (control), chemical crop protection, and artificial inoculation with the fungi F. graminearum and F. culmorum. Grains were analysed in terms of infection rate, mycotoxin, ergosterol, free and bound phenolic acid content, as well as antioxidant capacity. Calculated Fusarium head blight index (FHB index) ranged from 0% to 24% in the control, from 0% to 95% after inoculation and from 0 to 3% following chemical crop protection treatments. The highest concentration of ergosterol was detected in seeds from inoculated plots, with a mean value of 26.69 mg/kg. The highest mean concentration calculated for total toxin content was recorded after inoculation (7.833 mg/kg). The mean value for ferulic acid for inoculated samples resulted 2574 mg/kg, while for chemically protected samples 1158 mg/kg was obtained.Based on of discriminant analysis genotypes can be separated for inoculation 100%, for chemical crop protection 95%, and for natural infection 90%. Amongst 12 analysed phenolic acids the highest discrimination power was found for gallic acid, 4-hydroxybenzoic acid and vanillic acid.

“…Our present study, on grain from spring barley treated with a fungicidal preparation with tebuconazole as active ingredient, yielded similar results but the increase of DON levels was even more pronounced than in Magan's study. In other studies (HOPE et al 2000;SIRANIDOU & BUCHENAUER 2001), the levels of DON were also higher after treatment with a formulation containing azoxystrobin that was reported to be very effective in protecting Triticum durum against fusarioses (LANZELLOTTI 2002). In addition, azoxystrobin very effectively protected wheat (JENKYN & GUTTERIDGE 2002), spring barley (OVERTHROW 2002) and winter barley (COOKE et al 2002) against take-all disease.…”

“…HOPE et al (2000) had applied the fungicides azoxystrobin and propiconazol to wheat grain and found significantly increased production of DON in the presence of the fungicides. SIRANIDOU and BUCHENAUER (2001) stated that treatment of the plants with azoxystrobin reduced the disease index of spikes, but the DON content of the grain was higher than that of the untreated control. BAUER (2000) applied the fungicide Amistar (azoxystrobin) on wheat.…”

The influence of fungicides on the production of the trichothecene mycotoxin deoxynivalenol (DON) has been fairly intensively studied. MAGAN et al. (2002) examined the in vitro efficacy of fungicides to control Fusarium species in cereals and the effect in the field on both Fusarium infection of ripening ears and mycotoxin production. The field studies suggested that fungicides such as tebuconazole and metconazole provide good control of both Fusarium infection of ears and DON production.Azoxystrobin and related fungicides were less effective and grain from treated crops sometimes had an increased concentration of nivalenol and deoxynivalenol. Studies with F. culmorum isolates from different parts of Europe showed a complexity of interactions occurring between environmental factors, the type of fungicide and isolate in relation to growth inhibition and DON production. These studies confirmed the ineffectiveness of azoxystrobin and suggested that environmental stress Eight varieties of spring barley (Hordeum vulgaris Lin.) were artificially inoculated with a Fusarium culmorum (W.G. Smith) Saccardo -isolate and naturally infected in the middle of the flowering period, and 2 d later treated with the fungicides azoxystrobin or tebuconazol at a dose of 1 l/ha in 250 l of water. In both control and treated samples of grain the content of deoxynivalenol (DON), the main trichothecene mycotoxin produced by F. culmorum, was determined by gas chromatography (GC-ECD). The treatment with either fungicide resulted in elevated levels of DON, an effect that was more pronounced with azoxystrobin.

“…Siranidou et al (2002) reported a lower content of free phenols in spring wheat heads (below 700 µg·g −1 ), and demonstrated that the concentration of these compounds in spikes of cv. Frontana, resistant to FHB, was approximately threefold higher than in spikes of cv.…”

“…Phenols-saturated cell walls become more resistant to cytolytic enzymes produced by pathogens. Moreover, lignification slows down the diffusion of toxins contributing to pathogenesis, and restricts nutrient uptake by pathogens from the host cell (Siranidou et al 2002). The following enzymes take part in transformations of phenolic compounds in plants: phenylalanine ammonia-lyase, peroxidase and phenolic oxidases (Kunaeva 1986).…”

Abstract:The total concentrations of free phenolic compounds and peroxidase were determined in spikes (collected at the flowering stage) of some spelt and common wheat cultivars differing in their response to F. culmorum infection. The antifungal activity of methanol extracts obtained from spikes was also evaluated. The tested genotypes differed significantly in their response to inoculation. The most resistant were Torka and Zebra among common wheat cultivars, and Weisser Grannenspelz among spelt cultivars. The average content of free phenolic compounds in spikes of spelt and common wheat was 1246.56 µg g −1 and 1236.58 µg g −1 , respectively. The cultivars whose spikes contained the largest amounts of phenols showed the weakest response to F. culmorum infection. No significant differences were observed with regard to peroxidase content, which was 5.22 U g −1 in common wheat spikes and 5.14 U g −1 in spelt spikes. Methanol extracts from spikes of all wheat cultivars contained antifungal substances. The extracts from spelt spikes inhibited the growth of F. culmorum on PDA to a lesser degree than the extracts from common wheat spikes. This corresponds to the results of field trials, in which T. spelta generally exhibited a stronger response to F. culmorum infection than common wheat. The high correlation (r = 0.816) between mycelium growth inhibition on the medium and F. culmorum infection indicates that an evaluation of the antifungal activity of extracts from spikes may be used for the selection of breeding materials directed towards increased resistance to Fusarium head blight.
