The aim of this study was to find differences in the quantity and presence of selected polyphenolic substances in barley grown in the Czech Republic and in the People's Republic of China. The barley samples from China had a higher total amount of the polyphenols studied and a significantly higher amount of some specific groups of polyphenols. The most distinct differences were the significantly higher amount of procyanidin B3 and catechin in the free fractions (almost double) and of p-coumaric and ferulic acids in the bound fractions. Therefore, the specific conditions of cultivation's well as dissimilarity of barley varieties could be the source of...

Yields of spring barley and fluctuations in soil water in the critical period in terms of barley yield in the Czech Republic were evaluated for the period 1975-2010. On most sites there was statistically significant relationships between grain yield and soil water in different stages of vegetation; in some locations highly significant relationship. Statistically significant relationship was also found when evaluating average values of soil water and the average income in across stations. When evaluating the season-average soil water and yield a statistically significant (up to highly significant) effect of year 1976, 1981, 1985, 1986, 1995, 1996, 2000,...

In 2013, the spring barley varieties Kumran, Petrus, Shuffle, and Wiebke were registered after three-year tests (2010-2012) and Britney, Danielle, Explorer, Salome, and Scrabble after two-year tests (2011-2012) in the Slovak Republic. The highest extract was exhibited by the varieties Danielle (83.9%) and Shuffle (83.0%). All the studied varieties exhibited a very good to optimal level of proteolytic and amylolytic modification. The highest values of apparent final attenuation were recorded in the varieties Explorer (82.4%) and Wiebke (81.9%). The level of cell wall destruction given by friability (86-97%) was optimal in all the studied varieties....

Study evaluates quality of malting barley from harvest 2012 in the Czech Republic. The results from barley analyses showed favorable values of germination capacity, average starch content and above average protein content. Higher protein content was a reason of a lower extract content of the produced malts. To achieve optimal modification in samples with a higher protein content, a higher degree of steeping had to be applied. Based on the obtained results we can state that the year 2012 in terms of malt quality was an average year.Study evaluates quality of malting barley from harvest 2012 in the Czech Republic.
