Determinants of intra-industry agri-food trade in the Visegrad countries
The article analyses patterns and country-specific determinants of Visegrad Countries’ agri-food trade with the European Union. Literature focusing on the country-specific determinants of vertical and horizontal intra-industry trade is rather limited and those analysing agricultural (or agri-food) trade are extremely rare. Therefore, the paper seeks to contribute to the literature by covering the latest theories and data available on the topic to provide up to date results and suggestions. Moreover, it seeks to identify the determinants of horizontal and vertical intra-industry trade of the Visegrad Countries after EU accession. According to the results determinants of horizontal and vertical intra-industry differ and suggest that economic size is positively, while distance is negatively related to both sides of intra-industry trade. However, the relationship between vertical intra-industry trade and differences in factor endowments as well as foreign direct investment is ambiguous

Determinants of revealed comparative advantages: The case of cheese trade in the European Union
Revealed comparative advantages are widely used by the global literature to analyse international trade flows, though agricultural trade is usually neglected in empirical works. Moreover, the determinants of revealed comparative advantages are scarcely investigated. This article analyses revealed comparative advantages in European Union’s cheese trade from 1990 to 2013 and identifies its determinants by using panel data econometrics. Results suggest that GDP/capita, geographical indication, and EU membership are positively, while foreign direct investment (FDI) is negatively related to revealed comparative advantages

The Role of Culture, Language and Trade Agreements in Global Wine Trade
In the progressively globalising world, wine trade is changing shape. In recent decades, major wine producers have suffered a remarkable drop in their domestic wine consumption, while New World wine producers have increased their production potential and induced new demand in foreign markets. These changes have been accompanied by a geographical relocation of wine consumption and trade. The aim of our paper is to analyse the effect of cultural-geographical proximity, free trade and the role of linguistic similarity on bilateral wine trade in the world major wine producer countries, employing balanced panel gravity model. Regression results suggest that larger countries export more wine, while transport costs increase in line with geographical distance, especially for landlocked trading partners. Moreover, global wine export costs are lower if trading partners are culturally similar; have the same religion or both are members of the WTO or have regional trade agreements
In vitro propagation of 'Echo' cultivars of Eustoma grandiflorum (Raf.) Shinn.
Eustoma grandiflorum (Raf.) Shinn. 'Echo' Fl cultivars ('Echo White', 'Echo Rose', 'Echo Blue', 'Echo Blue Picotee') were used and multiplication of shoots was evaluated on Murashige and Skoog (1962) basal medium with 11 g/1 agar-agar and 20 g/1 sucrose. To test the effect of BA different concentrations were added: 0.10, 0.25 mg/1 and a culture medium without BA. Differentiation of roots was examined on Jámbor-Benczúr and Marta (1990) basal medium with the same concentration of agar-agar and sucrose. To examine the effect on rooting, various concentrations of NAA were used: 0.5, 1.0, 2.0, 3.0 mg/l. The pH was adjusted to 5.6 in every case using KOH. We studied the after-effect of different concentrations of BA during the acclimatisation. During the multiplication, the cultivar 'Echo White' formed the most shoots and the smallest leaves on the medium with 0.10 mg/1 BA. Fortunately, in the case of this cultivar, the number of shoots was reduced and the length of leaves was increased succesfully on the medium without BA. The other three cultivars developed the longest leaves on the medium containing 0.10 mg/1 BA. Sometimes not only shoot regeneration but spontaneous rooting was observed during the multiplication. Examining the rooting, the highest percent of roots was found on the medium with 1.0 mg/1 NAA, and the cultivar 'Echo Rose' formed the most roots on this medium. Higher concentration (2.0 and 3.0 mg/1) of NAA already reduced the number of roots in all of the cultivars. During the acclimatisation, the percentage of survival was 76.3% and the tallest plants with the longest leaves were found on the multiplication medium with 0.25 mg/1 BA. 'Echo Blue Picotee' gave the best results with the tallest pieces and longest leaves on this medium

The effects of growth regulators in proliferation of Sorbus redliana 'Burokvölgy'
The Hungarian cultivar Sorbus redliana 'Burokvölgy' was proliferated on Murashige and Skoog (MS, 1962) medium with half-strength macroelements and 100 mg/1 meso-inositol, 20 g/1 sucrose, 11 g/1 agar-agar. Different combinations of kinetin (KIN), metatopolin (mT), benzyladenine (BA), benzyladenine-ribosid (BAR) and indolebutiric acid (IBA) were tested, and pH was adjusted to 5.6 every case using KOH. The cultures were incubated at 20-24 °C in 8/16 hours dark/light photoperiod for 50-52 days. The main aim of our research was to find the optimal growth regulator and its optimum concentration. Purthermore, to determine the chlorophyll contents of the in vitro propagated plants' leaves. During the proliferation, the highest number of shoots were observed in the case of using BA + IBA, and on the medium containing 0.75 mg/I BA + 0.05 mg/1 IBA 8.93 shoots were found. The addition of KIN + IBA decreased the number of shoots and increased the sizes of leaves — the widest (11.2 mm) and longest (17.8 mm) leaves were obtained on the medium containing 1.00 mg/I KIN + 0.05 mg/1 IBA. The longest shoots (36.46 mm) were found in the case of applying 0.75 mg/1 BAR + 0.05 mg/I IBA. The BA + KIN + IBA combination resulted the shortest shoots. Sometimes not only shoot regeneration but spontaneous rooting was observed during the multiplication. The highest chlorophyll content (1.569 mg/g total chlorophyll, 1.132 mg/g chlorophyll-a, 0.437 mg/g chlorophyll-b) was obtained in the presence of 1.0 mg/I KIN + 0.05 mg/1 IBA
