Concentrations of phenolic acids are differently genetically determined in leaves, flowers, and grain of common buckwheat (Fagopyrum esculentum Moench)

Common buckwheat (Fagopyrum esculentum Moench) is a valuable source of proteins, B vitamins, manganese, tryptophan, phytochemicals with an antioxidant effect, and the natural flavonoid rutin. Due to its composition, buckwheat supports the human immune system, regulates blood cholesterol, and is suitable for patients with diabetes or celiac disease. The study aimed to compare the allocation of selected phenolic acids (neochlorogenic acid, chlorogenic acid, transcaffeic acid, trans-p-coumaric acid, trans-sinapic acid, trans-ferulic acid) and flavonoids (rutin, vitexin, quercetin, kaempferol) in the leaves, flowers, and grain of buckwheat cultivars of different origin. The content of individual phenolics was determined by the HPLC-DAD method. The results confirmed the determining role of cultivar on the relative content of chlorogenic acid, trans-caffeic acid, transsinapic acid, vitexin, and kaempferol in buckwheat plants. A significantly negative correlation among concentrations of phenolic acids in different common buckwheat plant parts shows that there are different mechanisms of genetic influences on the concentration of phenolic substances in common buckwheat flowers, leaves, and grain. These differences should be taken into account when breeding buckwheat for a high concentration of selected phenolic substances

Structural changes in agriculture since EU accession in Slovakia, the Czech Republic and Hungary

The collaboration that has led to the publication of this book can be traced back to April 2013, when the Research Institute of Agricultural and Food Economics (VÚEPP) in Bratislava, Slovak Republic, approached the Research Institute of Agricultural Economics (AKI) in Budapest, Hungary, with a view to establishing a programme of bilateral cooperation. The approach was very positively received by AKI, and the idea rapidly developed into a plan for a series of trilateral cooperation activities that also included the Institute of Agricultural Economics and Information (IAEI) in Praha, Czech Republic. Representatives of the three institutes met in Budapest at the end of May, 2013 and agreed to work together to enhance mutual research collaboration in the field of agricultural economics, share information and discuss issues related to agricultural economics in the three countries, and establish a coordination group composed by members of the three research institutes. The cooperation was formalised through the signing, in December 2013, of a trilateral Agreement covering the period 2014-2016 covering the following topics: (a) publication of individual or common papers in the institutes’ journals or other journals, and exchange of journals between institutes; (b) exchange of experience via trilateral meetings of specialists; (c) cooperation with other scientific entities and support for affiliation to international networks or construction of a specific network in the institutes’ common field of research interest; (d) applications and participation in common international projects; and (e) participation at international meetings with common research/papers and cooperation in organisation of different international meetings. The three institutes agreed that this would be an excellent way to better disseminate, nationally and internationally, the results of their research work and to open new perspectives to future mutual cooperation. The centrepiece of the programme of cooperation was a trilateral research project entitled “The CAP Impact on the Effectiveness of Use of Agricultural Production Factors and the Economic Efficiency of Agricultural Production and Product Sectors in the Slovak Republic, the Czech Republic and Hungary”. The general objective of this project has been: research on rural areas and the agrifood sector by sectoral analysis, country comparisons, identification of positive and negative influences on the rural and agricultural economy, dissemination of research results, and proposals for future policies in the field. Initially intended to cover four topics (implementation of the new Common Agricultural Policy (CAP), agricultural land ownership and related issues, competitiveness and profitability of crop and animal production, and the efficiency of food industry production), further discussion led to eight topics of joint research being agreed
