Abstract
Abstract The paper presents the results from the analysis of the 45 soil samples collected in 2010 from ten forest nurseries located at different regions of Slovak Republic. In total, 142 species of nematodes belonging to 87 genera were found. Out of them, 32 species are considered as plant feeders - parasites of higher plants, 11 species belong to fungal feeders, 10 species to root-fungal feeders, 8 species of predatory nematodes, 20 species of omnivorous nematodes and 49 species of bacteriovorous nematodes. The highest number of species was found in the Picea abies (94) and Quercus robur (80) rhizosphere. The survey results showed that communities of soil nematodes in forest nurseries are represented by all trophic groups of nematodes, but bacteriovorous, phytophagous and phyto-mycophagous nematodes prevailed and represented about 80% a total nematode fauna of coniferous and deciduous seedlings. The species of Acrobeloides nanus, Cephalobus persegnis, Rhabditis sp. juv.¸ Mesorhabditis sp.juv., Helicotylenchus digonicus, Paratylecnhus bukowensis, Trichodorus sprasus, Filenchus vulgaris, Malenchus exiguus, Tylencholaimus mirabilis, Tylencholaimus stecki belong to the most abundant at this study.
