In this system named GENOTYPDATA are incorporated specialized databases and descriptor sets enabling traits evaluation and their characterization on both the qualitative and quantitative levels. In the system are incorporated four databases – (i.) Taxonomy of genus Cornus, (ii.) Biology of species, (iii.) Catalogue of genotypes in the experimental set, and (iv.) Mathematical-statistical analysis of experimental data. The genotypes characteristics are supplemeted by images documenting the forms, width, lengths and further traits of leaves, flowers, fruits, seeds and other parts of plant. The GENOTYPDATA provides information on genotypes of Cornelian cherry, enables their comparison and selection based on the selected combination of various traits. Its utilization is multilateral in diffe...

Rhizosphere samples were taken from European chestnut (Castanea sativa Mill), true service tree (Sorbus domestica L.) and cornelian cherry (Cornus mas L.) plants. Experiments were conducted for three years during the vegetation period, and the bacterial community structure was assessed with cultivation-dependent approach. Many Gram-negative isolates (n = 251) from the rhizosphere survived sub culturing and were identified by biochemical tests. A total of 57 species belonging to 29 genera were identified and assigned to four broad taxonomic groups (Bacteroidetes, Alpha-, Beta- and Gamma-proteobacteria). Several specific bacterial cluster communities were identified inside all the three rhizospheres. Most of the species belonged to the genera Moraxella, Pseudomonas, Pantoea, Enterobacter and Acinetobacter. In addition, while, usin...

In all evaluated traits of genotypes on the level of tree habitat, leaves, fruits and stones significant differences were defined. In the experimental pool the following was assigned: fruit weight in the range 0.5-3.4 g, fruit length 12.0-19.5 mm, fruit width 7.4-15.2 mm, stone length 9.5-15.9 mm, stone width 4.5-8.9 mm, contents of vitamin C 16.4-38.5 mg/100 g, total sugars 6.5-15.1%, fructose 33.1-43.1%, glucose 53.6-63.1%, organic acids 4.6-7.4%, pH 2.7-3.2, proteins in flesh 3.4-5.0 g/kg, lipids in the stone 4.6%, lipids in the flesh 0.3%, linoleic acid from the volume of lipids in the stone 67.3% and in the flesh 36.54%. Based on the results that prove significant differences among genotypes the possibility of their selection for breeding purposes is proposed. On the majority of plants there were no significant pests and diseases detected. Some plants were afflicted by powdery mildew caused by Phyllactinia corni and Phyllactinia guttata.

At the same time their economical value and methodology of their utilisation are well known by the population of all Slovakia regions. Among the most important species should be listed the black mulberry (Morus nigra L.), true service tree (Sorbus domestica L.) and Cornelian cherry (Cornus mas L.), which exert several important functional characteristics.
