Functional compounds of einkorn and emmer genotypes

Three einkorn and two emmer genotypes were analysed for concentration of microelements (Fe, Zn and Se) and lipid soluble antioxidants (α-tocopherol, α-tocotrienol and β-carotene). A diversity was observed in micronutrient content, but most of the genotypes have significantly higher trace element and antioxidant contents than the control wheat variety. The emmer genotypes contain lower Fe and β-carotene concentration than einkorn genotypes. The einkorn genotypes have significant higher antioxidant content than the wheat control. On average einkorn has more than three times more β-carotene than the wheat variety. Our results are useful for species/variety choice in functional food production not only for organic but also for conventional farmers, who have/want to operate under low input conditions, especially in Central Europe

Impact of Bois Noir disease on grapevine performance and wine quality of <em>Vitis Vinifera</em> L. Cv. 'Chardonnay' in Hungary

Impact of "bois noir" disease (BN) on performance of 'Chardonnay' grown in Eger (Hungary) is reported from plant (vegetative and reproductive parameters, fruit composition) to wine (wine quality, sensory analysis). BN-associated chlorophyll degradation and leaf rolling resulted in a loss in functioning surface of the canopy. Lack of lignification and non-viable buds evoked unpredictable crop production. Severity and extent of reduction in production varied between years, but the crop loss was always above 53%. In the case of BN-affected grapevines the reduced quantity resulted in a low quality of grape bunch composition, which enhanced unfavourable outcomes in wines. Differences in fruit composition and wine quality between healthy and BN affected grapevines were most pronounced in years with optimal weather conditions and the negative effect was covered up in poor years. In wine regions where mechanical harvesting is applied, harvesting of phytoplasma diseased vineyards can therefore not be selective and qualitative. According to the three years study presented BN induce severe loss, and BN-affected plants compromise the yield and wine quality, and therefore the overall profitability of a vineyard
