“…On the other hand, β-glucans act favorably against such diseases as cardiovascular diseases and carcinomas of the alimentary tract. They reduce cholesterol and improve activity of the alimentary organs ( , ). For these reasons, it is important to adjust the β-glucan levels in barley and malt so that the requirements of beer producers are fulfilled while retaining nutritiously valuable substances.…”

Protection of barley grain against contamination by fungi such as Fusarium spp., particularly by those producing mycotoxins, secondary metabolites with adverse health effects, is of principal importance. Fungicides applied immediately after full heading of spring barley is one method of direct protection. In this work, extensive two-year field experiments combined with a detailed chemical laboratory analysis (barley and malt) were performed with the aim to study the effect of previous crops, different fungicides, and other conditions on the selected barley and malt quality parameters (content of beta-glucans, pentosans, oxalic acid, deoxynivalenol, and gushing), while the main task was to follow the effect of the fungicide (used as a treatment to protect against pathogens, mostly Fusarium) on changes of the chemical composition in barley and malt, and gushing. It was found that the relationship between the studied factors and the parameters usually applied to the evaluation of barley and malt quality is quite complex and not straightforward. The responses show typical features of a multifactorial influence with both positive and negative correlations resulting in a decrease or increase in grain quality (concentrations of beta-glucans, pentosans, deoxynivalenol, and other studied parameters). The role of previous crops was also found to be important. The fungicides should be applied at the time of heading but not at the very beginning of this period.

KOSAŘ, M., HOLKOVÁ, L., BŘEZINOVÁ BELCREDI, N., EHRENBERGEROVÁ, J.: HPPD gene expression in relation to vitamin E content in spring barley. Acta univ. agric. et silvic. Mendel. Brun., 2009, LVII, No. 4, pp. 13-18 The enzyme 4-hydroxyphenylpyruvate dioxygenase (HPPD) has a very important role in the biosynthetic pathway of vitamin E. Its activity infl uences the fi nal level of tocols in plant tissues. Seven barley cultivars with diff erent vitamin E level were grown under control conditions and activity of HPPD gene was measured four, eight and twelve days a er pollination of ear tissues. It was found that activity of HPPD gene corresponded with vitamin E content detected in grains (r = 0.77*). The relationship between the gene activity for HPPD eight and twelve days a er pollination and vitamin E content was also confi rmed for analyzed cultivars grown in the fi eld conditions (r = 0.85*).

Arabinoxylan and beta-glucan contents are limiting factors for a wider use of barley production. Arabinoxylan and beta-glucan contents were assessed in grain samples in sets of seven malting hulled varieties, three hull-less lines and one hull-less spring variety grown in the localities of Branišovice, Žabčice, and Kroměříž in 2009 to 2011. Further, the eff ect of growing technologies on the level of these non-starch polysaccharides was studied. Variability of arabinoxylan contents was aff ected most signifi cantly by a genotype and growing technology whereas variability of beta-glucan contents was mostly aff ected by a genotype and growing environment (interaction of year with locality). The highest values of arabinoxylans and beta-glucans were determined in the grain samples of hullless lines (KM 1057: 6.16% of arabinoxylans and KM 2084: 6.41% of beta-glucans) and on the contrary, the lowest values of arabinoxylans were found in the grain of hull-less variety AF Lucius (3.85%) and lowest amounts of beta-glucans were found in malting variety Radegast (3.92%). The samples of the growing technology without fungicide treatment had on average more arabinoxylans and betaglucans than the fungicide non-treated ones.
