The ascorbic acid, total polyphenols, total anthocyanins and mineral content, together with antioxidant activity, was determined in five Czech, two Ukrainian and two Austrian cultivars of cornelian cherry (Cornus mas L.) widely grown in the Czech Republic. Ascorbic acid content varied between 199–433 mg kg−1, total polyphenols between 2174–6143 mg kg−1, and total anthocyanins between 61–253 mg kg−1. All fruits were good sources of major metals (K, Ca, Mg, Fe, and Mn) and trace elements (Cu, Zn, and Cr). The antioxidant activity was determined by EPR and DPPH radical scavenging assay and ranged from 29.5% to 67.2%. There was a linear relationship between antioxidant activity and total polyphenol content. Based on the obtained results, Ekotišnovský, Fruchtal, and Ruzyňský cultivars were recommended for further investigation and breeding programme of cornelian cherry fruit in the Czech Republic.

Erwinia amylovora (Burrill, Winslow et al.) is one of the most important pathogens of pear and apple and subject to strict quarantine regulations worldwide. Fire blight disease causes serious damages in pear orchards in Hungary. The aim of our experiment was to test the susceptibility of pear cultivars to Hungarian E. amylovora isolates under laboratory conditions. For inoculation test isolates were chosen from different host plants, areas and years. Seven traditional pear cultivars were chosen for testing. Fruit infection was rated according to the diameter of spots produced by the pathogen around the inoculation puncture. Cultivars and isolates were assigned to five susceptibility groups (symptomless, low susceptibility, moderate susceptibility, susceptible and very susceptible). The Hungarian Erwinia amylovora isolates showed different results. We found different susceptibility of traditional pear cultivars. The cultivars Alexander Lucas and Stössel tábornok represented the less susceptible category. Eldorado, Serres Olivér, Diel vajkörte were moderately susceptible. Thus, the most susceptible cultivars were Téli esperes and Drouard elnök. In conclusion, these results can be used for the classification of Erwinia amylovora isolates and in future breeding programmes for resistance.

Surveying mycological works dealing with great number of species about basidial fungi published in the last hundred years (Kalchbrenner[1],Istvánffi[2],Hollós[3],Moesz[4, 5],Bohuset al. [6],Bánhegyiet al. [7],Ubrizsy[8],Bánhegyiet al.[9],Babos[10, 11],Rimóczi–Vetter[12],Rimóczi[13]) the great variety and changes of applied systems is conspicuous. In all works the doubt is expressed whether the currently applied systematic lists and nomenclatural solutions are the best, and whether they have chosen the most appropriate systematic theories.Hungarian authors have never created an own system though it is conspicuous that their knowledge about foreign mycologist taxonomist's works of the given period is thorough. Critical usage of their elements and critical review in the own works is rare (Ubrizsy–Vörös[14], Ubrizsy[15]).

Apricot is an important fruit species in Hungary both for fresh consumption and processing. Physical parameters and change of nutrients of nine apricot cultivars were studied during the ripening period. Four Hungarian and five North-American apricot cultivars were chosen for investigation. Changes in the physical parameters were measured by three different methods (Magness-Taylor hand penetrometer, Bookfield CT3 Texture Analyser with TA 44 and TA 9 measuring head). Significant differences in flesh firmness among the cultivars were observed mainly at the beginning of ripening time. Adhesiveness, cohesiveness and chewiness of the fruits decreased continuously during ripening. The studied cultivars showed significant differences in these traits. Sugar and acid contents were also measured during ripening. The cultivars showed small differences in sugar content and bigger differences in acid content of the fruits. Our data measured and collected during this study can be useful in characterizing the apricot cultivars studied. Changes in the texture parameters responsible for transportability and the technological usability of the fruits were described across the whole ripening period. Our results may help growers as well as food technologists to determine the optimum harvest date of cultivars intended to be used for different purposes.

Abstract  

Due to the disaster at the Chernobyl nuclear power station /26.04. 1986, USSR/ the radioactive contamination level /e.g.,134Cs,137Cs/ of the biosphere in Hungary increased significantly. The external -dose burden from the contaminated ground surface and atmosphere, and the radioactive isotopes taken up directly through the leaves and indirectly from the soil through the root system had a low-dose effect on the plants which was in the dose-range of stimulation /biopositive effect/.
