Qualitative And Quantitative

Grain samples of spring barley from the 2009 and 2010 harvest were analysed for the content of DNA of Fusarium species and Fusarium toxins (type B trichothecenes). Samples originated from different fields in Radzików, Central Poland. Qualitative and quantitative determination of Fusarium species in the grain was performed using a real-time PCR. Fusarium toxins in the grain were analysed by gas chromatography. Seven Fusarium species were detected in barley grain. The dominating species were F. avenaceum, F. graminearum and F. poae. The presence of F. culmorum, F. langsethiae, F. sporotrichioides and F. tricinctum was also detected. The concentration of trichothecene toxins in grain (deoxynivalenol, nivalenol) was low. The highest correlation coefficient of deoxynivalenol vs. Fusarium DNA was found for F. graminearum. Regarding nivalenol, the highest correlation coefficient was with F. poae DNA.

Technological Assessment

AbstractThe study was designed to assess technological quality of grains from two wheat cultivars (Elixer and Rockefeller), as well as one cultivar of winter (Joy) and one cultivar of spring barley (Irina), and to carry out the malting process at temperature of 15°C for 5 days. Malt analyses were carried out in accordance with the ECB Methods. The wheat malts were found with lower Kolbach index, and high viscosity was identified in wort obtained from wheat. The findings related to the wheat malts showed better quality parameters in Elixer variety compared to Rockefeller variety. Elixer wheat malt had higher diastatic power (427.03 WK) and lower extractivity (81.85%) compared to Joy barley malt (376.12 WK and 85.79%). Laboratory tests assessing the malts and wort showed that winter barley grain has high malting quality and can be used without modifications in the malting and mashing processes in brewing industry. It is necessary to conduct further research focusing on cultivation, agricultural techniques and technologies applied in wheat farming, in order to obtain cultivars which can be used to produce high quality malts.

Fungi of the genus Fusarium, known as toxigenic species, are very of- ten parasites and contaminants of brewer's barley. In this paper, the composition of the genus Fusarium species in brewer's barley samples and their potential in the zearalenone synthesis were investigated. The tests were done on different brewer's barley varieties, crop 2003, samples (SSK1, SSK2, SSK3 SSK4, SSK5, SSK6, SSK7, SSK8, SSK9, SSK10 and SSK12) from Kragujevac locality. The isolation and identification of the Fusarium species were done according to the methods described by N e l s o n et al. (1983). The identified Fusarium species (6) were tested for their capacity to synthesise zearalenone. The isolates were cultivated on sterilised barley grains at the temperature of 25?C for 14 days, and then the zearalenone concentration was determined by the fluorometric method on the fluorometer "VI- CAM" series 4. The following seven Fusarium species were isolated from barley samples: F. acuminatum, F. avenaceum, F. culmorum, F. equiseti, F. poae, F. sporotrichioides and F. tricinctum. F. poae was the most distributed species (10.26%). The zearalenone concentration within the range of 12.0 to 430.0 g kg-1 was determined in cultures of barley grain inoculated with F. avenacuem (SSK6 and SSK12), F. culmorum (SSK8), F. tricinctum (SSK1), F. sporotrichioides (SSK7 and SSK12) and F. poae (SSK5, SSK9 and SSK10). Isolates of F. equiseti (SSK2) and F. poae (SSK6) did not express capacity to synthesise this toxic metabolite.

Barley Crop

Field research to determine the influence of weed control systems in winter barley on subsequently no-till-planted grain sorghum was conducted from 1985 to 1987 in northwest Georgia. Herbicide treatments applied to fully tillered winter barley included 2,4-D, dicamba, metribuzin, oryzalin, oryzalin plus metribuzin, fluorochloridone, or thiameturon. None of these herbicides affected barley grain yields compared to nontreated plots. Treatments containing oryzalin reduced johnsongrass fresh weights in the subsequently planted grain sorghum. Oryzalin plus metribuzin, in 1 of 2 yr, resulted in higher seed yields of subsequently planted grain sorghum compared to the other treatments except for oryzalin used alone. Treatments containing paraquat plus propazine plus metolachlor applied to grain sorghum provided good weed control when averaged across barley treatments and resulted in the highest grain sorghum yield. No grain sorghum injury from herbicides used in the previous winter barley crop was observed.
